Message Description
D1
1. Initialize KBC and RTC
D2
1. Check BIOS Checksum
D3 1.
Initialize
IOH
2. Initialize
ICH10
3. Initialize
SIO
4. Initialize
IPMI
5. Initialize Intel RC code
D4
Test base 512KB memory. Adjust policies and cache first 8MB. Set stack
D5
Boot block 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.
D7
Restore CPUID value back into register. The Boot block 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.
DA
Restore CPUID value back into register. Give control to BIOS POST.
Boot Block Recovery Code
Checkpoints
E0
Initialize the floppy controller in the super IO. DMA controller is initialized. 8259
interrupt controller is initialized. L1 cache is enabled.
E9
Set up floppy controller and data. Attempt to read from floppy
EA
Enable ATAPI hardware. Attempt to read from ARMD and ATAPI CDROM
EB
Disable ATAPI hardware. Jump back to checkpoint E9
EF
Read error occurred on media. Jump back to checkpoint EB
E9 or EA
Determine information about root directory of recovery media
F0
Search for pre-defined recovery file name in root directory
F1
Recovery file not found
F2
Start reading FAT table and analyze FAT to find the clusters occupied by the
recovery file
F3
Start reading the recovery file cluster by cluster
F5
Disable L1 cache
FA
Check the validity of the recovery file configuration to the current configuration of the
flash part
FB
Make flash write enabled. Detect proper flash part. Verify that the found flash part
size equals the recovery file size
F4
The recovery file size does not equal the found flash part size
FC
Erase the flash part
FD
Program the flash part
FF
The flash has been updated successfully. Make flash write disabled. Disable ATAPI
hardware. Restore CPUID value back into register
Post Code Checkpoints
03
Disable NMI, Parity, video for EGA and DMA controllers. Initialize BIOS, POST,
Runtime Data area. Also initialize BIOS Modules on POST entry and GPNV area.
04
Check CMOS diagnostic byte to determine if battery power is OK and CMOS
