Bootblock Recovery Code Checkpoint

The bootblock recovery code gets control when the BIOS determines that a BIOS recovery
needs to occur because the user has forced the update or the BIOS checksum is corrupt. The
following table describes the type of checkpoints that may occur during the bootblock recovery
portion of the BIOS:

information is stored in memory.
Store the Uncompressed pointer for future use in PMM. Copying
OFF A Main BIOS into memory. Leaves all RAM below 1 MB Read-Write
including E000 and F000 shadow areas but closing SMRAM.
Restore CPUID value back into register. Give control to BIOS POST

LSB
Initialize the floppy controller in the super I/O. Some interrupt vectors
R OFF are initialized. DMA controller is initialized. 8259 interrupt controller is
initialized. L1 cache is enabled.
Set up floppy controller and data. Attempt to read from floppy.
R G
Determine information about root directory of recovery media.
Enable ATAPI hardware. Attempt to read from ARMD and ATAPI
A OFF CD-ROM. Determine information about root directory of recovery
media.
A G Disable ATAPI hardware. Jump back to checkpoint E9.
A G Read error occurred on media. Jump back to checkpoint EB.
R R Search for pre-defined recovery file name in root directory.
R A Recovery file not found.
Start reading FAT table and analyze FAT to find the clusters
A R
occupied by the recovery file.
A A Start reading the recovery file cluster by cluster.
R A Disable L1 cache.
Check the validity of the recovery file configuration to the current
A R
configuration of the flash part.
Make flash write enabled through chipset and OEM specific method.
A A Detect proper flash part. Verify that the found flash part size equals
the recovery file size.
R R The recovery file size does not equal the found flash part size.
R R Erase the flash part.
R A Program the flash part.
