Netfinity 5000 - Recovering BIOS
Applicable to: World-Wide
Recovering BIOS
If your BIOS has become corrupted, such as from a power failure during a flash update, you can recover your BIOS using the recovery boot block and a BIOS flash diskette.
|
Note |
The flash memory of your server contains a protected area that cannot be overwritten. The recovery boot block is a section of code in this protected area that enables the server to start up and to read a flash diskette. The flash utility automatically recovers the system BIOS from the BIOS recovery files on the diskette.
To recover the BIOS:
1. See Option Installation through Preparing a Tower Model or through Preparing a Rack Model for instructions on powering off the server and removing the cover. Then, refer to the system-board diagram inside your server for the location of the switch block.
2. Locate switch 5 (see System Board Switches).
3. Set switch 5 on the switch block to On, to set boot block recovery mode.
4. Insert the BIOS flash diskette in the diskette drive.
5. Restart the server.
Nothing appears on the display monitor, but the diskette drive activity LED and periodic beeps indicates that BIOS recovery is under way. Recovery is complete when slow beeps are concluded by a string of fast beeps and the Post Complete light on the operator LED panel is on.
6. Remove the flash diskette from the diskette drive.
7. Turn the server off.
8. Set switch 5 to Off, to return to normal startup mode.
9. Restart the server. The system should start up normally.
