POST code checkpoints list
Bootblock initialization code checkpoint
The following table describes the Award common tasks carried out by POST. An unique checkpoint number
denotes each task. .
Checkpoint Description
Before D1 Early chipset initialization is done. Early super I/O initialization is done including RTC
and keyboard controller. NMI is disabled.
D1 Perform keyboard controller BAT test. Check if waking up from power management
suspend state. Save power-on CPUID value in scratch CMOS.
D0 Go to flat mode with 4GB limit and GA20 enabled. Verify the bootblock checksum.
D2 Disable CACHE before memory detection. Execute full memory sizing module.
Verify that flat mode is enabled.
D3 If memory sizing module not executed, start memory refresh and do memory sizing in
Bootblock code. Do additional chipset initialization. Re-enable CACHE. Verify that
flat mode is enabled.
D4 Test base 512KB memory. Adjust policies and cache first 8MB. Set stack.
D5 Bootblock code is copied from ROM to lower system memory and control is given to
it. BIOS now executes out of RAM.
D6 Both key sequence and OEM specific method is checked to determine if BIOS
recovery is forced. Main BIOS checksum is tested. If BIOS recovery is necessary,
control flows to checkpoint E0. See Bootblock Recovery Code Checkpoints section
of document for more information.
D7 Restore CPUID value back into register. The Bootblock-Runtime interface module is
moved to system memory and control is given to it. Determine whether to execute
serial flash.
D8 The Runtime module is uncompressed into memory. CPUID information is stored in
memory.
D9 Store the Uncompressed pointer for future use in PMM. Copying Main BIOS into
memory. Leaves all RAM below 1MB Read-Write including E000 and F000 shadow
areas but closing SMRAM.
DA Restore CPUID value back into register. Give control to BIOS POST
(ExecutePOSTKernel). See POST Code Checkpoints section of document for more
information.
