FailSafe Boot Block
The FailSafe Boot Block enables BIOS recovery in the unlikely event of a ROM flash failure. For
example, if a power failure occurs during a ROM upgrade, the Boot Block uses a flash-protected
section of the ROM to verify a valid system ROM flash when power is restored to the computer.
If the system ROM is valid, the computer starts normally.
If the system ROM fails the validation check, the FailSafe Boot Block provides enough support to start
the computer from a BIOS image CD created from a SoftPaq. The BIOS image CD programs the
system ROM with a valid image.
When Boot Block detects an invalid system ROM, the computer power LED blinks red eight times and
the computer beeps eight times; then the computer pauses for two seconds. On some models, a Boot
Block recovery mode message appears.
In preparation for system recovery, use the BIOS CD media file in the SoftPaq to create a BIOS
image CD or USB key.
