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