The following table describes the type of checkpoints that may occur during the POST portion of the BIOS: Checkpoint 03 04 05 06 08 0A 0B 0C 0E 13 24 30 2A 2C 2E 31 33 Description Disable NMI, Parity, video for EGA, and DMA controllers. Initialized CMOS as mentioned in the Kernel Variable "wCMOSFlags. " Check CMOS diagnostic byte to determine if battery power is OK and CMOS checksum is OK. If the CMOS checksum is bad, update CMOS with power-on default values and clear passwords. Initializes both the 8259 compatible PICs in the system Initializes the interrupt controlling hardware (generally PIC) and interrupt vector table. Traps INT1Ch vector to "POSTINT1ChHandlerBlock. " Initializes the CPU. Program the keyboard controller command byte is being done after Auto detection of KB/MS using AMI KB-5. Traps the INT09h vector, so that the POST INT09h handler gets control for IRQ1. Uncompress all available language, BIOS logo, and Silent logo modules. Detects and initializes the video adapter installed in the system that have optional ROMs. Set the window for displaying text information. 85 http://www. tyan. com Checkpoint 37 38 39 3A 3B 3C 40 Description Displaying sign-on message, CPU information, setup key message, and any OEM specific information. Detect different devices (Parallel ports, serial ports, and coprocessor in CPU, . . . etc. ) successfully installed in the system and update the BDA, EBDA. . . Programming the memory hole or any kind of implementation that needs an adjustment in system RAM size if needed. [. . . ] The CPU is lightly placed in an open ZIF socket, and a lever is pulled down. This shifts the processor over and down, guiding it into the board and locking it into place. 115 http://www. tyan. com Technical Support If a problem arises with your system, you should turn to your dealer for help first. Your system has most likely been configured by them, and they should have the best idea of what hardware and software your system contains. Furthermore, if you purchased your system from a dealer near you, you can bring your system to them to have it serviced instead of attempting to do so yourself (which can have expensive consequences).
