Performing a BIOS Recovery

Boot Block

An interruption during a BIOS flash procedure (e.g. a power outage) can corrupt the BIOS
code, which will cause the system to go into an unbootable state. The BIOS boot block refers
to a special BIOS program that can be used to boot up a system with minimum BIOS
initialization.You need to access and execute the boot block to reboot the computer and
recover the regular BIOS code.
