It will be referred to as the LSI21002 throughout this manual. Installing the LSI21002 in your PCI system allows connection of SCSI devices over a SCSI bus. The dual channel LSI21002 provides 16-bit Low Voltage Differential (LVD) and Single-Ended (SE) SCSI solutions for your computer, using only one PCI slot. This board supports legacy Fast SCSI devices, Ultra SCSI devices, and the newest Ultra2 SCSI devices. Channel A supports only the SE mode. Channel B supports SE and LVD modes of operation. The Storage Device Management System (SDMS™) software operates the board. The design of the board does not prevent other software from being used with it. This guide, along with the PCI Storage Device Management System SDMS 4.0 User’s Guide, contains product information and installation instructions to help you gain the full benefits of the LSI21002.

The PCI functionality for the LSI21002 is contained within the LSI53C896 PCI Dual Channel SCSI Multifunction Controller. The LSI53C896 connects directly to the PCI bus and generates timing protocol in compliance with the PCI specification. The PCI interface operates as a 32-bit DMA bus master. The connection is made through edge connector J1 (see Figure 2.1). The signal definitions and pin numbers conform to the PCI Local Bus Specification Revision 2.1 standard. The LSI21002 conforms to the PCI universal signaling environment for a 5 V or 3.3 V PCI bus. 1.3.2 The SCSI Interface The SCSI functionality for the LSI21002 is contained within the LSI53C896 chip. The LSI53C896 connects directly to the two SCSI buses for SE or LVD SCSI applications and generates timing and protocol in compliance with the SCSI standard. One SCSI interface operates at a burst transfer rate of up to 40 Mbytes/s for wide Ultra SCSI transfers, and the other up to 80 Mbytes/s for wide Ultra2 SCSI transfers. Channel A is SE only with active autosensing termination. The Channel A interface is made through connectors J2, J3, and J4. Connector J2 is a 68-pin high density latching right angle receptacle for internal SCSI connections. Connector J3 is a 50-pin high density right angle receptacle that protrudes throughout the ISA/EISA bracket. Connector J4 is a 50-pin narrow (ribbon) internal connector. Channel B may be either SE or LVD with active termination always enabled. The Channel B interface is made through connector J5. J5 is a 68-pin high density latching right angle connector for internal SCSI connections. 1-4 Using the LSI21002 See Figure 2.1 for the location of these connectors. The LSI21002 supplies SCSI bus TERMPWR through a blocking diode and self-resetting 1.5 A short circuit protection device. An on-board LED lights up when TERMPWR is shorted and has turned off. A 40 MHz oscillator is installed on the LSI21002 to provide the clock frequency to the LSI53C896 that is necessary to support SCSI transfers. 1.3.3 SCSI Activity LED Interface The LSI21002 LED interface is a four-wire arrangement that allows connection of an LED harness to the board. The connector on the LSI21002 is J6 for both channels. See Table A.7 in Appendix A for the signal name and pin numbers for this LED interface. 1.3.4 Wide Ultra2 SCSI The LSI21002 has full support for Wide Ultra2 SCSI. This interface is an extension of the SCSI-3 family of standards that expands the bandwidth of the SCSI bus to allow faster synchronous data transfers, up to 80 Mbytes/s. Wide Ultra2 SCSI provides a doubling of the data rate over the Ultra SCSI interface, while it allows increased cable length and more devices than Ultra SCSI interfaces. Special SCSI cables are specified for operation with Wide Ultra and Ultra2 SCSI devices, and you must consider the total number of devices and the length of your SCSI bus when setting up your system. The section on connecting your SCSI peripherals in Chapter 2, "Installing the LSI21002," provides a more detailed explanation of SCSI bus connections. See Table 1.1for maximum bus lengths in meters. When you purchased the LSI21002 kit, the cable provided in the kit is matched for a Fast/Ultra/Ultra2 SE or LVD operation. This cable also has built-in LVD termination since most Ultra2 hard disk drives are not made with on-board LVD termination. Interface Descriptions 1-5 Table 1.1 Standard Cables Maximum Bus Length, Meters1 STA Term SE LVD Maximum Devices Wide Ultra SCSI 1.5 see note2 8 Wide Ultra SCSI 3 see note2 4 Wide Ultra2 SCSI see note3 12 16 1. This parameter may be exceeded in point-to-point and engineered applications. 2. LVD was not defined in the original SCSI standards for this speed. If all devices on the bus support LVD, then 12-meter operation is possible at this speed. However, if any device on the bus is SE only, then the entire bus switches to SE mode, and the distances in the SE column apply. 3. SE and high power differential are not defined at Ultra2 speeds. 1-6 Using the LSI21002 Chapter 2 Installing the LSI21002 This chapter describes installing the LSI21002 into PCI computer systems and includes these topics: • Section 2.1, “Quick Installation Procedure,” page 2-1 • Section 2.2, “Detailed Installation Procedure,” page 2-3 • Section 2.3, “Setting Interrupts (Exceptional Cases),” page 2-24 • Section 2.4, “Completing the Installation,” page 2-25 2.1 Quick Installation Procedure This section provides quick setup instructions for the experienced computer user with prior host adapter installation and SCSI bus setup experience. If you prefer more detailed guidance for installing the LSI21002, please follow the instructions in Section 2.2, “Detailed Installation Procedure.” For safe and proper installation, check the user’s manual that was supplied with your computer and perform the following steps. Step 1. Before proceeding, ground yourself so that a static discharge does not damage the board. Remove the LSI21002 from the packing and check that it is not damaged. An example of this host adapter board is shown in Figure 2.1. Step 2. Switch off and unplug the system. Step 3. Remove the cabinet cover on your computer to access the PCI slots. Caution. Ground yourself by touching a metal surface before handling boards. Static charges on your body can damage electronic components. Handle plug-in boards by the edge; LSI21002 PCI to Dual Channel SCSI Host Adapter 2-1 do not touch board components or gold connector contacts. The use of a static ground strap is recommended. Step 4. Locate the slots for the PCI plug-in board installation. A 32-bit slot should be used. The LSI21002 will work in a 64-bit slot, but only 32 bits are used. The LSI21002 requires a PCI slot that allows bus master operation. See Figure 2.2. Step 5. Remove the blank panel on the back of the computer aligned with the PCI slot that you intend to use. Save the bracket screw. Step 6. Carefully insert edge connector J1 of the host adapter into the PCI slot. Make sure the edge connector is properly engaged before pressing the board into place. See the example shown in Figure 2.2. Note. You may notice that the components on the PCI host adapter face the opposite way from those on other non-PCI plug-in boards you have in your system. This is correct, and the board is keyed to go in only one way. Step 7. The bracket around connector J3 should fit where the blank panel was removed. Secure it with the bracket screw before making the internal and external SCSI bus connections (see Figure 2.2). Step 8. If you are connecting any internal SCSI devices, plug a 68-pin connector on the end of the internal SCSI ribbon cable into connector J2 or J5, or plug a 50-pin connector into J4 for an 8-bit SCSI (see Figure 2.1). Make certain to match pin 1 on all connectors. Note. It is possible to use both internal connectors if no external devices are attached to the host adapter. You may use only two of the three connectors at once. Step 9. Connect your computer’s LED cable if desired. This LED cable drives the front panel LED found on most PC cabinets to indicate activity on the SCSI bus. See Table A.7 in Appendix A for the signal name and pin numbers for this LED interface. Step 10. Replace the cabinet cover as described in the user’s manual for your computer. Step 11. Make all external SCSI bus connections. 2-2 Installing the LSI21002 Remember: The SCSI bus requires proper termination and no duplicate SCSI IDs. Step 12. Refer to the PCI Storage Device Management System SDMS 4.0 User’s Guide (or the guide for the software that you will use) to load the driver software for your particular operating system. 2.2 Detailed Installation Procedure This section provides step-by-step instructions for installing your LSI21002 and connecting it to your SCSI peripherals. If you are experienced in these tasks, you may prefer to use Section 2.1, “Quick Installation Procedure.” If you are not confident that you can perform the tasks as described here, LSI Logic suggests getting assistance. 2.2.1 Before You Start Before you start, look through the task list below to get an overall idea of the steps to perform. • Open your PC cabinet and select an open PCI slot • Insert the host adapter • Connect your internal and external SCSI peripherals • Terminate the SCSI bus • Set the peripheral SCSI IDs • Make any configuration changes • Replace your PC cabinet cover • Install the software The SCSI host adapter acts on your computer’s behalf as the host to your suite of SCSI peripherals. Each chain of SCSI peripheral devices and their host adapter work together, and they are referred to as a SCSI bus. Detailed Installation Procedure 2-3 2.2.2 Inserting the Host Adapter For safe and proper installation, check the user’s manual supplied with your computer and perform the following steps: Step 1. Before proceeding, ground yourself so that a static discharge does not damage the board. Remove the LSI21002 from the packing and check that it is not damaged. An example of this host adapter board is shown in Figure 2.1. Step 2. Switch off and unplug power cords for all components in your system. Step 3. Remove the cabinet cover on your computer to access the PCI slots. Caution: Ground yourself by touching a metal surface before removing the cabinet cover. Static charges on your body can damage electronic components. Handle plug-in boards by the edge; do not touch board components or gold connector contacts. The use of a static ground strap is recommended. Step 4. Locate the slots for the PCI plug-in board installation. A 32-bit slot should be used. The LSI21002 will work in a 64-bit slot, but only 32 bits are used. The LSI21002 requires a PCI slot that allows bus master operation. See Figure 2.2. Step 5. Remove the blank panel on the back of the computer aligned with the PCI slot that you intend to use. Save the bracket screw. Step 6. Carefully insert edge connector J1 (see Figure 2.1) of the host adapter into the PCI slot. Make sure the edge connector is properly engaged before pressing the board into place as shown in Figure 2.2. Step 7. You may notice that the components on the PCI host adapter face the opposite way from those on other non-PCI adapter boards you have in your system. This is correct, and the board is keyed to go in only one way. 2-4 Installing the LSI21002 Step 8. The bracket around connector J3 (see Figure 2.1) should fit where you removed the blank panel. Secure it with the bracket screw (see Figure 2.2) before making the internal and external SCSI bus connections. Figure 2.1 Hardware Connections for the LSI21002 Channel B 68-Pin Internal High Density SCSI Connector J5 Channel A 68-Pin Internal High Density SCSI Connector J2 Channels A and B Busy LED Connector J6 Channel A 50-Pin External HD SCSI Connector J3 Channel A 50-Pin Internal Narrow SCSI Connector J4 LSI21002 PCI Bus Edge Connector J1 Detailed Installation Procedure 2-5 Figure 2.2 Inserting the Host Adapter Bracket Screw 32-bit Slot 64-bit Slots 2.2.3 Connecting the SCSI Peripherals All internal SCSI bus connections to the LSI21002 are made with an unshielded, 68- or 50-conductor ribbon cable (see Figure 2.3). One side of this cable is marked with a color to indicate the pin-1 side. The connectors on this cable are keyed to ensure a proper pin-1 connection. Use Ultra/Ultra2 rated cables for these bus speeds. (See Table 1.1 in Chapter 1.) 2-6 Installing the LSI21002 For convenience, Channel A also has a 50-pin narrow (ribbon) connector. Some internal cables come with an SE/LVD terminator on one end. This end should be furthest from the host adapter. All external SCSI bus connections to the LSI21002 are made with a shielded, 50-pin high density cable (see Figure 2.3). The connectors on this cable are always keyed to ensure a proper pin-1 connection. Figure 2.3 SCSI Cables SCSI Cable for Internal Connections 68-Pin High Density and/or 50-Pin Low Density SCSI Cable for External Connections 50-Pin High Density Detailed Installation Procedure 2-7 2.2.3.1 Making Internal SCSI Bus Connections This section provides step-by-step instructions about making internal SCSI bus connections: Step 1. To connect an internal SCSI device, plug the 68-pin connector end of a wide internal SCSI ribbon cable into connector J2 or J5. See the example in Figure 2.4. Figure 2.4 Internal SCSI Ribbon Cable to Host Adapter J5 J2 J4 J3 2-8 Installing the LSI21002 Step 2. Plug the 68-pin connector on the other end of the wide internal SCSI ribbon cable into the SCSI connector on the internal SCSI device. Pin 1 must match on all connections. An example of this connection appears in Figure 2.5. Figure 2.5 Internal SCSI Ribbon Cable to Internal SCSI Device Connection Detailed Installation Procedure 2-9 Step 3. To plug in additional internal SCSI devices, use an internal SCSI ribbon cable with the required number of connectors attached along its length. See the example in Figure 2.6. Figure 2.6 2-10 Connecting Additional Internal SCSI Devices Installing the LSI21002 An example of multiple internal SCSI devices chained together is shown in Figure 2.7. Make sure to match pin 1 on all connections. Figure 2.7 Multiple Internal SCSI Devices Chained Together Detailed Installation Procedure 2-11 Step 4. Most PC cabinets are designed with a front panel LED, which may already be connected to an existing IDE controller. You may connect this LED cable to your SCSI host adapter, as shown in Figure 2.8. This connection causes the front panel LED to indicate activity on the SCSI bus. The Busy LED connector J6, shown in Figure 2.1, is not keyed. The J6 connector is a 4-pin one row right angle header for both Channel A and Channel B. Some LED cables have only two wires. In this case, place the connector on one end of J6. If the LED does not light during SCSI bus activity from this host adapter, you may have to rotate the LED connector 180° on J6. See Table A.7 in Appendix A for connector pinout information. Figure 2.8 2-12 SCSI LED Connector Installing the LSI21002 2.2.3.2 Making External SCSI Bus Connections This section provides step-by-step instructions about making external SCSI bus connections: Step 1. To connect external SCSI devices to the LSI21002, plug the 50-pin high density connector on one end of a shielded external high density cable (see Figure 2.3) into the host adapter connector J3 (see Figure 2.1 and Figure 2.9). This connector is now bracketed onto the back panel of your computer. Figure 2.9 shows this connection. Figure 2.9 External Cable to Host Adapter Detailed Installation Procedure 2-13 Step 2. Plug the 50-pin high density connector on the other end of the shielded external SCSI cable into the SCSI connector on the external SCSI device. An example of this connection is shown in Figure 2.10. Figure 2.10 External Cable to External SCSI Device 2-14 Installing the LSI21002 Step 3. To connect more than one external SCSI device to the host adapter, chain them together with shielded external SCSI cables. See the example in Figure 2.11. Figure 2.11 Multiple External SCSI Devices Chained Together 2.2.4 SCSI Bus Termination The devices that make up the SCSI bus are connected serially (chained together) with SCSI cables. The first and last physical SCSI devices connected on the ends of the SCSI bus must be terminated. All other SCSI devices on the bus must have their terminators removed or disabled. Detailed Installation Procedure 2-15 Remember: The LSI21002 is also on the SCSI bus, and its termination is automatically enabled when it is connected to the end of the bus. LVD peripheral devices are normally terminated with external terminators, but are sometimes set with jumpers or with a switch on the peripheral. Refer to the peripheral manufacturer’s instructions and to your computer user’s manual for information on how to identify the terminator setting of each device and how to change it. Caution: The autoenable/disable sensing feature of Channel A on the LSI21002 may enable termination erroneously if it is directly cabled to another SCSI device or host adapter using the same sensing method. The LSI21002 senses SCSI devices by detecting the ground signal on conductor 50 of a 68-conductor SCSI cable or conductor 22 of a 50-conductor SCSI cable. Only the SE/LVD terminators on Channel B will always remain on. When connecting another host adapter to a connector, termination must be disabled on the board that is not at the end of the bus through software control. The LSI21002 automatically controls SCSI bus termination for four different bus configurations, depending on the use of connectors (see Figure 2.1). The four bus configurations are: • Only for internal SCSI connections, • Only for an external SCSI connection, and • Connections to both internal and external SCSI connectors • Connections to both internal connectors. Termination on the LSI21002 for these four different bus configurations are discussed below. Please note that only SE termination control is allowed on Channel A. 2.2.4.1 Internal SCSI Connections If only internal SCSI device connections on the host adapter have been made, then terminate the last internal device on the SCSI bus. You must disable the termination on all other devices. Termination on the LSI21002 2-16 Installing the LSI21002 is automatically enabled for Channel A. The termination for Channel B is enabled all the time. Figure 2.12 shows an example of how termination is determined for this SCSI bus configuration. Figure 2.12 Internal SCSI Device Termination Detailed Installation Procedure 2-17 2.2.4.2 External SCSI Connections If only external SCSI device connections to the host adapter have been made, then terminate the last external device on the SCSI bus. You must disable the termination on all other devices. Termination on the host adapter is automatically enabled for Channel A. Figure 2.13 shows an example of how termination is determined for this SCSI bus configuration on the host adapter external Channel A. Figure 2.13 External SCSI Device Termination Last Device on Chain – Termination Enabled Does Not End Chain – Termination Disabled Host Adapter Automatically Terminated 2-18 Installing the LSI21002 2.2.4.3 Internal and External SCSI Connections If internal and external SCSI devices are connected to the host adapter, then terminate the last internal and external devices on the SCSI bus. You must disable the termination on all other devices. Termination on Channel A of the host adapter is automatically disabled in this case. Figure 2.14 shows an example of how termination is determined for this SCSI bus configuration on the host adapter internal Channel A and external Channel A. Detailed Installation Procedure 2-19 Figure 2.14 Internal and External SCSI Device Termination Last Device on Chain – Termination Enabled Does Not End Chain – Termination Disabled Last Device on Chain – Termination Enabled 2-20 Installing the LSI21002 2.2.4.4 Internal SCSI Connections for both Internal Connectors If internal SCSI device connections to both internal connectors (J2 and J4) on your host adapter have been made, then terminate the internal devices on each end of the SCSI bus. You must disable the termination on all other devices. Termination on Channel A of your host adapter is automatically disabled in this case. Remember, you must not use the external connector J3 if you use both internal connectors. Figure 2.15 shows an example of how termination is determined for this SCSI bus configuration Figure 2.15 Internal and Internal SCSI Device Termination Last Devices on Chain – Termination Enabled Does Not End Chain – Termination Disabled Host Adapter Termination Automatically Disabled Detailed Installation Procedure 2-21 2.2.4.5 Setting SCSI IDs You must set each SCSI device and the host adapter to a separate SCSI ID, 0–15 for a 16-bit SCSI. SCSI ID 7 is the preset host adapter setting, giving it the highest priority on the SCSI bus. If you plan to boot your computer from a hard disk drive on the SCSI bus, that drive should have SCSI ID 0, or the lowest SCSI ID on the bus. Chapter 3, "Configuring the Host Adapter," explains how to set the host adapter ID using the LSI Logic SCSI BIOS Configuration Utility. The peripheral device SCSI IDs are usually set with jumpers or with a switch on the peripheral. Refer to the peripheral manufacturer’s instructions and to the user’s manual for your computer to determine the ID of each device and how to change it. You must have no duplication of SCSI IDs on a SCSI bus. Note: SCAM support is turned off by default for the BIOS version 4.11.00 and above. You may choose to turn this on to assist in assigning SCSI IDs. Determine the SCSI ID of each device on the SCSI bus. Note any duplications. 2-22 Installing the LSI21002 Make any necessary changes to the SCSI IDs and record the IDs for future reference. Table 2.1 is provided as a place to keep this record.

However, if your system does not support two separate interrupts, INTA/INTB/ (see Figure A.1) is provided to change the interrupt routing. This capability requires enabling the INTA/INTB/ to act as a jumper for special configuration purposes. This feature is not packaged with the standard LSI21002, as the default interrupt routing is sufficient for most systems. In the exceptional case, where a user would require jumper settings, Table 2.2 explains these settings: Table 2.2 Setting Interrupts Jumper Setting Condition Jumper Out (default) SCSI Channel B is routed to INTB/ on the PCI bus Jumper In SCSI Channel B is rerouted to INTA/ on the PCI bus Contact Technical Support for further information concerning jumper settings for this board. 2-24 Installing the LSI21002 2.4 Completing the Installation Before replacing the cover on your computer, review this installation procedure check list.

Completing the Installation 2-25 2-26 Installing the LSI21002 Chapter 3 Configuring the Host Adapter This chapter describes configuring the LSI21002 and includes these topics: • Section 3.1, “When to Configure the LSI21002,” page 3-1 • Section 3.2, “Starting the SCSI BIOS Configuration Utility,” page 3-2 • Section 3.3, “Exiting the SCSI BIOS Configuration Utility,” page 3-14 3.1 When to Configure the LSI21002 In most cases you should not need to change the default configuration of your host adapter. You may decide to alter these default values if there is a conflict between device settings, or if you need to optimize system performance. Table 3.1 and Table 3.2 list the configuration settings you can change. The global settings effect your host adapter and all SCSI devices that are connected to it. The device settings affect only individual SCSI devices. Table 3.1 Global Default Settings Settings for the Host Adapter and All Devices Default Settings SCAM Support Off1 Parity Checking Enabled Host Adapter SCSI ID 7 Scan Order Low to High (0-Max) 1.

You may decide to alter these default values if there is a conflict between device settings or if you need to optimize system performance. You can see the version number of your SCSI BIOS in a banner displayed on your computer monitor during boot. If the utility is available, the following message also appears on your monitor: Press Ctrl-C to start LSI Logic Configuration Utility... This message remains on your screen for about five seconds, giving you time to start the utility. If you decide to press “Ctrl-C,” the message changes to: Please wait, invoking LSI Logic Configuration Utility... After a brief pause, your computer monitor displays the Main Menu of the LSI Logic SCSI BIOS Configuration utility. NonVolatile Random Access Memory (NVRAM) is provided on the LSI53C896 SCSI device. 3-2 Configuring the Host Adapter Important: This utility is a powerful tool. If, while using it, you somehow disable all of your controllers, pressing Ctrl-A (or Ctrl-E on version 4.04 or later) after memory initialization during reboot allows you to re-enable and reconfigure. Not all devices detected by the Configuration Utility can be controlled by the BIOS. Devices such as tape drives and scanners require that a device driver specific to that peripheral be loaded. This device driver is provided by the device manufacturer. 3.2.1 Configuration Utility Main Menu When you start the LSI Logic SCSI BIOS Configuration Utility, the Main Menu appears. This menu displays a list of up to four LSI Logic PCI to SCSI host adapters and information about each of them. The LSI21002 appears on the menu as two LSI53C896 entries; one for each channel. To select an adapter, use only the arrow keys and enter key. Then, you can view and/or change the current settings for that adapter and the SCSI devices attached to it. You can select an adapter only if Current Status is “On”. Changes are possible since NVRAM is present on this host adapter. Figure 3.1 is an example of the Main Menu: Starting the SCSI BIOS Configuration Utility 3-3 Figure 3.1 Main Menu Main Menu Port Num LSI53C895 LSI53C896 LSI53C896 FC00 F800 F801 Irq---------Status--------NVRAM Level Current Next-Boot Found 9 9 9 On On On On Off Off Yes Yes Yes Change Adapter Status Adapter Boot Order Additional Adapter Configuration Display Mode = Verbose Mono/Color Language Help Quit Below the list of host adapters on the Main Menu display, you see eight options. They are described in detail below. If these settings are altered, the system reboots upon exit from the Configuration Utility using the Quit option. 3.2.1.1 Change Adapter Status Change Adapter status allows you to activate or deactivate a host adapter and all SCSI devices attached to it. When this option is used to make a change, the change takes place after a reboot that is automatic upon exit from the utility.

Then press the Escape (Esc) key to exit from this menu. 3.2.1.2 Adapter Boot Order Adapter Boot Order allows you to set the order in which host adapters will boot when you have more than one LSI Logic host adapter in your system. When this option is selected, the Boot Order Menu appears. Figure 3.3 is an example of the Boot Order Menu: Figure 3.3 Boot Order Menu Main Menu BootSeq Bus DevFunc BootSeq 0 LSI53C895 00 A0 2 LSI53C896 00 90 1 Bus DevFunc LSI53C896 00 98 To change an adapter's boot order, select it and press Enter. You are then prompted to enter the new boot sequence number. To remove an adapter's boot order, press Enter again rather than entering a new sequence number. While the maximum capacity is 32 adapters, only 0 through 3 can be assigned a boot order. If an invalid number is entered, an error message appears. When the adapters are ordered as desired, press the Escape (Esc) key to exit from this menu. Starting the SCSI BIOS Configuration Utility 3-5 3.2.1.3 Additional Adapter Configuration Additional Adapter Configuration allows you to configure an adapter that is not assigned a boot order. When this option is selected, the Adapter Configuration Menu appears.

The message Resetting Adapter, Please wait appears, and then the system scans for devices. The Utilities Menu appears and lists the available options, which are described below. 3.2.1.4 Display Mode Display Mode determines how much information about your host adapters and SCSI devices appear on your computer monitor during boot. For more complete information, choose the verbose setting. For a faster boot, choose the terse setting. 3.2.1.5 Mono/Color Mono/Color allows the user to choose between a monochrome or color display for the SCSI BIOS Configuration Utility. If needed, choose the mono setting to get a more readable screen on a monochrome monitor. 3.2.1.6 Language If enabled, the Language option allows you to select from five languages for the Configuration Utility: English, German, French, Italian, and Spanish. Call Technical Support if you have any additional questions. 3-6 Configuring the Host Adapter 3.2.1.7 Help The Help option allows the user to bring up a help screen with information about the Main Menu. 3.2.1.8 Quit The Quit option allows exiting from the SCSI BIOS Configuration Utility when the Main Menu is displayed. 3.2.1.9 Esc Pressing the Esc key allows exiting from all the screens except the Main Menu. 3.2.2 Utilities Menu When you select a host adapter on the Main Menu, the Utilities Menu appears. Figure 3.5 is an example of the Utilities Menu: Figure 3.5 Utilities Menu LSI53C896 Adapter Setup Device Selections Help Exit this menu Choose Adapter Setup to view and change the selected adapter settings. Choose Device Selections to view and change settings for the devices attached to the selected adapter. You are returned to this menu after making changes to the configuration of any host adapter or connected SCSI device. Before exiting from this menu, you are prompted to save or cancel any changes. Starting the SCSI BIOS Configuration Utility 3-7 3.2.2.1 Adapter Setup Menu When you select Adapter Setup, the corresponding menu appears. Figure 3.6 is an example of the Adapter Setup Menu: Figure 3.6 Adapter Setup Menu Adapter Setup SCAM Support Off Parity None Host SCSI ID 7 Scan Order Low to High <0..Max> Removable Media Support None CHS Mapping SCSI Plug & Play Mapping Spinup Delay (secs) 2 Secondary Cluster Server No Termination Auto Help Restore Default Setup Exit this menu The settings in this menu are global settings that affect the selected host adapter and all SCSI devices attached to it. SCAM Support – The LSI Logic BIOS Version 4.XX and above supports the SCSI Plug and Play protocol called SCAM. SCAM support by default is turned off in versions 4.11.00 and later for the LSI53C896 device. You may choose to turn it on. Note that if this BIOS is flashed onto a board with existing settings, then these settings will not be changed to reflect the new BIOS defaults. Go into the Configuration Utility to change settings. 3-8 Configuring the Host Adapter Parity – The LSI Logic PCI to SCSI host adapters always generate parity, but some older SCSI devices do not. Therefore, you are offered the option of disabling parity checking. Note: When disabling parity checking, it is also necessary to disable disconnects for all devices, as parity checking for the reselection phase is not disabled. If a device does not generate parity, and it disconnects, the I/O never completes because the reselection never completes. Host SCSI ID – In general, it is suggested that you do not change your host adapter ID from the default value of 7, as this gives it the highest priority on the SCSI bus. Scan Order – This option allows the user to tell the SCSI BIOS and device drivers to scan the SCSI bus from low to high (0 to max) SCSI ID, or from high to low (max to 0) SCSI ID. If you have more than one device on the SCSI bus, changing the scan order changes the order in which drive letters are assigned by the system. Drive order may be reassigned differently in systems supporting the BIOS Boot Specification (BBS). See the PCI Storage Device Management System SDMS 4.0 User’s Guide, Chapter 2 “SCSI BIOS” for additional information regarding BBS. Note: The scan order option may conflict with operating systems that automatically assign a drive order. Removable Media Support – This option defines the removable media support for a specific drive. When this option is selected, a window appears with three choices: • None Indicates there is no removable media support whether the drive is selected in BBS as being first, or first in scan order in non-BBS. • Boot Drive Only Provides removable media support for a removable hard drive if it is first in the scan order. • With Media Installed Provides removable media support wherever the drive(s) actually resides. Starting the SCSI BIOS Configuration Utility 3-9 One of these choices can be selected by highlighting it and pressing Enter. CHS Mapping – This option defines the cylinder head sector (CHS) values that will be mapped onto a disk without pre-existing partitioning information. SCSI Plug and Play Mapping is the default value. To support interchange with noncompatible systems, there is another option that can be selected by choosing CHS Mapping and then cursoring to Alternate CHS Mapping. Note: Neither of these options will have any affect after the disk has been partitioned with the FDISK command. To remove partitioning, two options are available: • Reformat the disk using the Format Device option. See Section 3.2.2.2, “Device Selections Menu.” • Use the FDISK/MBR command at the C:\ prompt, where MBR represents master boot record. Important: Reformatting the disk or using FDISK/MBR erases all partitioning and data that exists. Be careful that you target the correct disk when using either the Format utility or the FDISK/MBR command. After clearing the partitions and data, it is necessary to reboot and clear the memory or the old partitioning data will be reused. Spinup Delay (seconds) – This option allows the user to stagger spin ups between devices for a longer period of time to balance the total current load. The default value is 2 seconds with choices between 1 and 10 seconds. This is a power management feature designed to accommodate disk devices that may have heavy current load during power up. If multiple drives are being powered up simultaneously and drawing heavy current loads, then this option staggers the spin ups to limit start-up current. Secondary Cluster Server – This option allows the user to enable an adapter to join a cluster of adapters without doing any SCSI bus resets. 3-10 Configuring the Host Adapter This is a requirement for Microsoft Cluster Server. The default value is No with an alternate option of Yes. Termination – This option allows the user to have termination control providing an adapter has controllable termination. The default value is Auto termination. The alternate value is Off. 3.2.2.2 Device Selections Menu When you select the Device Selections option, the corresponding menu appears. Figure 3.7 is an example of the Device Selections Menu: Figure 3.7 Device Selections Menu Device Selections 0-7 Sync Data Rate Width 0-Dev0 N/A 80 16 1-Dev1 N/A 80 2-Dev2 N/A Disc Time Scan Queue Initial Out Bus LUNS Tags Boot On 10 Yes Yes On No 16 On 10 Yes Yes On No 80 16 On 10 Yes Yes On No 3-Dev3 N/A 80 16 On 10 Yes Yes On No 4-Dev4 N/A 80 16 On 10 Yes Yes On No 5-Dev5 N/A 80 16 On 10 Yes Yes On No 6-Dev6 N/A 80 16 On 10 Yes Yes On No LSI53C896 80 16 On 10 Yes Yes On No Device Selections 8-15 Help Exit this menu The settings in this menu affect individual SCSI devices attached to the selected host adapter. Changes made from this menu do not cause the system to reboot upon exit from the SCSI BIOS Configuration Utility. To Starting the SCSI BIOS Configuration Utility 3-11 change a value, select the required device by using the arrow keys and press Enter. A new menu appears providing the options and utilities available. See an example of this menu in Figure 3.8: Figure 3.8 Device Selections Menu (Cont.) LSI53C896 Sync Rate Width Disconnect Read/Write I/O Timeout (secs) Scan for Device at Boot Time Scan for SCSI LUNs Queue Tags Initial Boot Format Verify Help Restore Default Setup Exit this menu Sync Rate (Mbytes/s) – This option defines the maximum data transfer rate the host adapter attempts to negotiate. The host adapter and a SCSI device must agree to a rate they can both handle. Width (Bits) – This option defines the maximum SCSI data width the host adapter attempts to negotiate. The host adapter and a SCSI device must agree to a width they can both handle. Only host adapters that can do 16-bit data transfers have this option enabled. Disconnect – SCSI devices have the ability to disconnect from the initiator during an I/O transfer. The disconnect option frees the SCSI Bus 3-12 Configuring the Host Adapter to allow other I/O processes. This option tells the host adapter whether or not to allow a device to disconnect. Some devices run faster with disconnects enabled (typically newer devices), while some run faster with disconnects disabled (typically older devices). Read/Write I/O Time-out (Seconds) – This option sets the amount of time the host adapter waits for a read, write, or seek command to complete before trying the I/O transfer again. Since this provides a safeguard allowing the system to recover if an I/O operation fails, it is recommended that you always set the time-out to a value greater than zero. Note: If the time-out is set to zero, then the I/O will never time-out. Scan for Device at Boot Time – Set this option to “No” when there is a device you do not want to be available to the system. Also, on a bus with only a few devices attached, you can speed up boot time by changing this setting to “No” for all unused SCSI IDs. Scan for SCSI Logical Unit Numbers (LUNs) – Set this option to “No” if you have problems with a device that responds to all LUNs whether they are occupied or not. For example, if there is a SCSI device with multiple LUNs but you do not want all of those LUNs to be available to the system, then set this option to “No.” This will limit the scan to LUN0 only. Queue Tags – This option allows the user to enable or disable the issuing of queue tags during I/O requests when your device driver can do this. Initial Boot – This option allows any device attached to the first adapter to become the boot device. It provides the users of non-BBS personal computers with some of the flexibility of a BBS machine. Format – If enabled, this option allows the user to low-level format a magnetic disk drive. Low-level formatting will completely and irreversibly erase all data on the drive. Note that this utility will only format 512-byte sectors. For other sector sizes, do not use this utility. Verify – This option allows the user to read all the sectors on a disk looking for errors. When selected, this option displays the following message: Starting the SCSI BIOS Configuration Utility 3-13 “Verify all sectors on the device Press ESC to abort Else press any key to continue” Help – This option displays a help screen with information about the current menu. Restore Default Setup – This option resets all device selections back to their optimal settings. Select this option to restore all manufacturing defaults for the specified adapter. Note that all user customized options will be lost upon saving after restoring default setup. Exit this menu – This option allows the user to leave the current menu screen and return to the previous screen. 3.3 Exiting the SCSI BIOS Configuration Utility Some changes only take effect after your system reboots. It is important that you exit this SCSI BIOS Configuration Utility properly. Return to the Main Menu and exit by using the Quit option. 3-14 Configuring the Host Adapter Appendix A Technical Specifications This section discusses the physical environment associated with the LSI21002 and includes a mechanical drawing of the LSI21002 (Figure A.1). • Section A.1, “Physical Environment,” page A-1 • Section A.2, “Operational Environment,” page A-4 A.1 Physical Environment The LSI21002 has specific physical, electrical, thermal, and safety characteristics, which are described in the next sections.

A.1.1 Physical Characteristics The dimensions of the LSI21002 are approximately 190.5 mm x 96.52 mm (7.5 x 3.8 inches). PCI connection is made through edge connector J1. The component height on the top and bottom of the LSI21002 follows the PCI specification. Internal 16-bit SCSI connection is made through 68-pin high density connectors; J2 for Channel A or J5 for Channel B. External SCSI connection is made to Channel A through the 50-pin high density connector J3. A-2 Technical Specifications Channel A also has connector J4, which is a 50-pin narrow (ribbon) connector for internal connections. Connector J3 extends through the ISA/EISA bracket, which is attached to the face of the connector outside of the cabinet where the LSI21002 is installed. Connector J6 connects the Busy LED. It is a 4-pin, one row, right angle header and indicates bus activity for both Channel A and Channel B. A.1.2 Electrical Characteristics The LSI21002 maximum power requirements, which include SCSI TERMPWR, under normal operation are as follows: Table A.1 Maximum Power Requirements +5 V DC ±5% 3.0A Over the operating range 5 °C to 55° C +12 V DC ±5% 0.1A Over the operating range 5 °C to 55° C (used while programming Flash BIOS) The PCI PRSNT1# and PRSNT2# pins are set to indicate a 15 W maximum configuration. Under abnormal conditions, such as a short on SCSI TERMPWR, + 5 V current may be higher. At temperatures of at least 25 °C, a current of 4 A is sustained no longer than thirty seconds before the self-resetting TERMPWR short circuit protection device opens. A.1.3 Thermal, Atmospheric Characteristics The board is designed to operate in an environment, which is defined by the following parameters: • Temperature range: 0 to 55 °C (dry bulb) • Relative humidity range: 5% to 90% (noncondensing) • Max dew point temperature: 32 °C The board is designed for a storage and transit environment, which is defined by the following parameters: • Temperature range: − 45 °C to + 105 °C (dry bulb) • Relative humidity range: 5% to 90% (noncondensing) Physical Environment A-3 A.1.4 Electromagnetic Compliance The board is designed and implemented so as to minimize electromagnetic emissions, susceptibility, and the effects of electrostatic discharge. The board carries the CE mark, and meets the requirements of FCC and CISPR Class B. It is also marked with the FCC self-certification logo. A.1.5 Safety Characteristics The bare board meets or exceeds the requirements of UL flammability rating 94 V0. The bare board is also marked with the supplier’s name or trademark, type, and UL flammability rating. Since this board is installed in a PCI bus slot, all voltages are below the SELV 42.4 V limit. A.2 Operational Environment The LSI21002 is designed for use in PCI computer systems with an ISA/EISA bracket type. The SDMS software operates the board; however, the design of the board does not prevent the use of other software. An on-board flash memory device is provided to allow BIOS code and open boot code support through the PCI bus and a serial EEPROM for each channel. A.2.1 The PCI Interface The PCI interface operates as a 32-bit DMA bus master. The connection is made through edge connector J1, which provides connections on both the front and back of the board. The signal definitions and pin numbers conform to the PCI Local Bus Specification Revision 2.1 standard. The signal assignments appear in Table A.2 and Table A.3. Note: A-4 The + 3.3 V pins are tied together and decoupled with high frequency bypass capacitors to ground. No current from these 3.3 V pins is used on the board. The PCI portion of the LSI53C896 chip is powered from the 3 V/5 V pins.

A-6 Technical Specifications A.2.2 The SCSI Interface The SCSI interface conforms to ANSI X3T10.11/1142. The SCSI interface operates as two 16-bit, SE or LVD channels, and supports Fast, Ultra, and Ultra2 SCSI protocols. The interface is made through connectors J2, J3, and J4 for Channel A and J5 for Channel B. J2 is a 68-pin high density latching right angle connector for internal SCSI connections to Channel A. J3 is a 50-pin high density right angle connector that protrudes through the ISA/EISA bracket for external connections to Channel A. Also on Channel A is connector J4, which is a 50-pin narrow (ribbon) connector for internal connections. Channel A has auto-sensing, active SE SCSI termination. J5 is a 68-pin high density latching right angle connector for internal SCSI connections to Channel B. Channel B has Active, SE or LVD SCSI termination that is always enabled. SCSI termination power is supplied by the board. Tables A.4, A.5, A.6, and A.7 show the signal assignments for J2, J3, J4 and J5 respectively (see Figure 2.1, in Chapter 2).

An encoded three-bit number for the logical unit. LVD Low Voltage Differential. LVD is a robust design methodology that improves power consumption, data integrity, cable lengths and support for multiple devices, while providing a migration path for increased I/O performance. Mainboard A large circuit board that holds RAM, ROM, the microprocessor, custom integrated circuits, and other components that make a computer work. It also has expansion slots for host adapters and other plug-in boards. Glossary B-3 Main Memory The part of a computer’s memory which is directly accessible by the CPU (usually synonymous with RAM). Mbyte Megabyte. A measure of computer storage equal to 1024 kilobytes. Motherboard See Mainboard. In some countries, the term Motherboard is not appropriate. Multitasking The initiation and control of more than one sequence of operations. This allows programs to operate in parallel. Multithreading The simultaneous accessing of data by more than one SCSI device. This increases the aggregate data throughput. NVRAM NonVolatile Random Access Memory. Actually an EEPROM (Electronically Erasable Read Only Memory chip) used to store configuration information. See EEPROM. Operating System A program that organizes the internal activities of the computer and its peripheral devices. An operating system performs basic tasks such as moving data to and from devices, and managing information in memory. It also provides the user interface Parity Checking A way to verify the accuracy of data transmitted over the SCSI bus. One bit in the transfer is used to make the sum of all the 1 bits either odd or even (for odd or even parity). If the sum is not correct, an error message appears. SCSI uses odd parity. PCI Peripheral Component Interconnect. A local bus specification that allows connection of integrated peripheral controller components, peripheral add-in boards, and processor/memory systems. It bypasses the slower ISA and EISA busses. Peripheral Devices A piece of hardware (such as a video monitor, disk drive, printer, or CD-ROM) used with a computer and under the computer’s control. SCSI peripherals are controlled through a SCSI host adapter. Pin-1 Orientation The alignment of pin-1 on a SCSI cable connector and the pin-1 position on the SCSI connector into which it is inserted. External SCSI cables are keyed to ensure proper alignment, but internal SCSI ribbon cables may not be. B-4 Glossary PIO Programmed Input/Output. A way the CPU can transfer data to and from memory using the computer’s I/O ports. PIO can be faster than DMA, but requires CPU time. Port Address Also Port Number.
