5-4 Chapter 5: BIOS Updating Procedures
BIOS Crisis Recovery
The procedures below provide a way to restore the BIOS resulting
from a non-recoverable condition.
Note:
Use this BIOS crisis recovery procedure only for a
NON-RECOVERABLE BIOS failure. A non-recoverable BIOS state
typically results from power loss during a flash BIOS update process.
This is a rare occurrence and should not be confused with other
hardware errors that cause a
no video state. This procedure is not
intended to be used for changing or upgrading an operational BIOS .
