Bootblock Recovery Code Checkpoints
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.
NOTE: NOTE:
Checkpoints may differ between different platforms based on system configuration.
Checkpoints may change due to vendor requirements, system chipset or option ROMs
from add-in PCI devices
