The LSI22801 is a PCI-dual channel
multi-function, single-ended Ultra
SCSI solution.
OVERVIEW
The LSI22801 host adapter is a multi-function board providing two
independent single-ended Ultra SCSI channels. Both SCSI channels are
identical, offering increased connectivity without utilizing additional PCI
slots. A single board provides a powerful dual channel, multitasking interface
for Ultra SCSI peripherals such as disk, tape, CD-ROM, and other SCSI devices.
The LSI22801 leverages the LSI53C876 PCI dual channel SCSI multifunction controller capable of connecting directly to the PCI bus, presenting
one electrical load, while functioning as a single 32-bit PCI DMA bus master.
The LSI22801 includes an on-board configuration utility allowing
viewing and changing of default configuration settings for the host adapter
and connected SCSI peripherals.
The device also provides advanced features for ease of use by modifying
the on-board terminators depending on cable configuration and LEDs to
help with termination power (TERMPWR) monitoring.
The LSI22801 has advanced features which makes it the right choice for
applications requiring up to 30 connected peripherals, or for isolating
peripheral classes (e.g. CD-ROMs and tape drives on one channel and high
performance disk drives on the other).
LSI22801 SCSI Host Adapter
PCI FEATURES
TECHNICAL DESCRIPTION
• True multi-function device
(per PCI 2.1 Specification)
– uses only one PCI slot
The LSI22801 uses the LSI53C876 PCI dual channel SCSI multi-function
controller. This single-chip multi-function device connects directly to the PCI bus.
• Functions as one 32-bit PCI
DMA bus master
• Two independent DMA channels
with internal programmable
arbitration
TERMINATION CONTROL
For each channel the adapter will automatically determine when cables
are attached to which connector and properly enable or disable the SCSI
terminators. The Table 1 below shows which cable combinations are allowed.

LSI22801 utilizing the two internal and two external SCSI connectors
• Universal 3.3V and 5V PCI
Four jumpers included to manually force the different cable configurations.
SCSI FEATURES
TERMINATION POWER
• 16-bit Ultra SCSI design based
on the popular LSI53C875 for
maximum performance
One LED per channel is included to indicate the status of termination power
(TERMPWR).
• Local memory bus for FLASH
memory BIOS storage
• SCSI TolerANT™ active
negation SCSI driver and
receiver technology
• SCAM (SCSI Configured
AutoMatically) Level 1
functionality for SCSI
plug-and-play support
• External VHDCI SCSI connector

CONFIGURATION UTILITY
The resident menu-driven BIOS configuration utility allows the viewing and
changing of the default settings for the host adapter and SCSI devices. The
following table lists the configuration settings which can be changed. The
global settings affect the host adapter and all SCSI devices connected to it.
The host adapter boot order can be changed if more than one SCSI host
adapter solution is implemented, see Table 2.
INTERRUPTS
The host adapter includes a jumper to select separate interrupts (channel A
routed to INTA# pin and channel B routed to INTB# pin) or shared interrupts
(channel A and channel B routed to INTA#/ pin).
SUBSYSTEM ID
SOFTWARE FEATURES
Subsystem ID and Subsystem Vendor ID support enables users to develop custom
software while still using a standard board configuration.
• Support for DOS, Windows 95,
Novell NetWare, Windows NT,
UnixWare, and SCO Open
