Recovering The Bios With The Crisis Recovery Diskette - Intel SE7520BD2 User Manual

NOTE
BIOS recovery is the mode of last resort, used only when the main system
BIOS will not come up.

Recovering the BIOS with the Crisis Recovery Diskette

Automatically Recovering the BIOS
If a ROM checksum error occurs during POST, the system will automatically enter BIOS recovery
mode. This is indicated by system beeping with one long beep followed by two short beeps. When
you hear this beep pattern, use the following steps to initiate an automatic recovery:
1. Insert the Crisis Recovery Diskette into the A: diskette drive.
2. A blue screen will be displayed and the recovery process will automatically run. The system
will continue to beep throughout the recovery process.
3. A series of three beeps and no disk access signals the need to insert disk two.
4. When the beeping stops and disk access stops on disk two the recovery process is complete.
5. Remove disk two.
6. Power down and unplug the system from the AC power source.
7. Plug the system into the AC power source and power it up to confirm that the recovery was
successful.
Manually Recovering the BIOS
A BIOS recovery can be manually initiated. This option would be used only when the BIOS is
corrupt, but the ROM checksum error does not occur during POST. To manually initiate a BIOS
recovery, use the following steps:
1. Power down and uplug the system from the AC power source.
2. Install the recovery jumper at J4H1. See the figure below.
