All configured parameters are stored in a flash chip to save the setup information whenever the power is turned off. This chapter provides users with detailed description about how to set up basic system configuration through the AMI BIOS setup utility. 4.1 Starting To enter the setup screens, follow the steps below: 1. 2. Turn on the computer and press the <Del> key immediately. After you press the <Del> key, the main BIOS setup menu displays. You can access the other setup screens from the main BIOS setup menu, such as the Advanced and Chipset menus. If your computer cannot boot after making and saving system changes with BIOS setup, you can restore BIOS optimal defaults by setting JP10 (see section 2.3.6). Note It is strongly recommended that you should avoid changing the chipset’s defaults. Both AMI and your system manufacturer have carefully set up these defaults that provide the best performance and reliability. 4.2 Navigation Keys The BIOS setup/utility uses a key-based navigation system called hot keys. Most of the BIOS setup utility hot keys can be used at any time during the setup navigation process. These keys include <F1>, <F2>, <Enter>, <ESC>, <Arrow> keys, and so on. Some of the navigation keys differ from one screen to another.

Some embedded systems are not watched by operator for 24 hours. It is usually too slow to wait for someone to reboot when computer hangs. The systems need to be able to reset automatically when things go wrong. The watchdog timer gives us solution. The watchdog timer is a counter that triggers a system reset when it counts down to zero from a preset value. The software starts counter with an initial value and must reset it periodically. If the counter ever reaches zero which means the software has crashed, the system will reboot. A.2 How to Use Watchdog Timer The I/O port base addresses of watchdog timer are 2E (hex) and 2F (hex). The 2E (hex) and 2F (hex) are address and data port respectively. Assume that program A is put in a loop that must execute at least once every 10ms. Initialize watchdog timer with a value bigger than 10ms. If the software has no problems; watchdog timer will never expire because software will always restart the counter before it reaches zero.

Command byte Command Protocol Function 0 1 2 3 Read byte Read/write byte Read/write byte Read/write byte Input port register Output port register Polarity inversion register Configuration register The command byte is the first byte to follow the address byte during a write transmission. It is used as a pointer to determine which of the following registers will be written or read. Register 0: Input port register. This register is a read-only port. It reflects the incoming logic levels of the pins, regardless of whether the pin is defined as an input or an output by Register 3. Writes to this register have no effect. The default ‘X’ is determined by the externally applied logic level, normally ‘1’ when no external signal externally applied because of the internal pull-up resistors.

This register reflects the outgoing logic levels of the pins defined as outputs by Register 3. Bit values in this register have no effect on pins defined as inputs. Reads from this register return the value that is in the flip-flop controlling the output selection, not the actual pin value. Register 1 – Output port register bit description Bit Symbol Access Default Value Description 7 6 5 4 3 2 1 0 O7 O6 O5 O4 O3 O2 O1 O0 R R R R R R R R 1 1 1 1 1 1 1 1 Reflects outgoing logic levels of pins defined as outputs by Register 3. Register 2: Polarity Inversion register. This register allows the user to invert the polarity of the Input port register data. If a bit in this register is set (written with ‘1’), the corresponding Input port data is inverted. If a bit in this register is cleared (written with ‘0’), the Input port data polarity is retained. Register 2 – Polarity inversion register bit description Bit Symbol Access Default Value Description 7 6 5 4 3 2 1 0 N7 N6 N5 N4 N3 N2 N1 N0 R/W R/W R/W R/W R/W R/W R/W R/W 0 0 0 0 0 0 0 0 Inverts polarity of Input port register data. 0 = Input port register data retained (default value). 1 = Input port register data inverted. Register 3: Configuration register. This register configures the directions of the I/O pins. If a bit in this register is set, the corresponding port pin is enabled as an input with high-impedance output driver. If a bit in this register is cleared, the corresponding port pin is enabled as an output. At reset, the I/Os are configured as inputs with a weak pull-up to VDD.
