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.
