Bootblock Recovery Codes
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.
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

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.
