Creating a Crisis Recovery Diskette
A crisis recovery diskette should always be prepared before attempting to upgrade the BIOS. This diskette is
used to reprogram the BIOS in case the flash process fails.
To create a crisis recovery diskette:
1) Turn on the server and allow the POST to complete. If thePOST detects an error and take the appropriate
steps to correct the problem. After the problem has been resolved, restart the server.
2) Insert the startup and utilities diskette and make sure the following files are in the UPGRADE directory:
MINIDOS.SYS
PHLASH.EXE
DEVTBLS.DAT
PHLASH.INI
PRIORISHX.ROM
MAKEBOOT.EXE
MAKECRD.EXE
3) Create the same directory on the hard disk drive and then copy the above files to it.
4) Insert a blank formatted diskette into drive A.
5) From drive C: type
MAKECRD
. This copies the files to drive A.
6) Remove the crisis recovery diskette from drive A and store it in a safe place.
Using the Crisis Recovery Diskette
The crisis recovery diskette must be used only if the server’s BIOS fails or if a BIOS upgrade was unsuccessful
♦
POST detects an error after a normal boot cycle or a BIOS upgrade.
♦
The BIOS in the bootblock memory executes.
♦
The server beeps several times.
♦
The diskette drive begins searching for the crisis recovery diskette.
If the server’s BIOS fails:
1)
Turn off the server and set the recovery jumper (J39) to recovery mode.
2) Insert the crisis recovery diskette into drive A and power on the server.
3) After the BIOS is restarted, turn off the power and remove the crisis recovery diskette from drive A.
4) Set the recovery jumper (J39) back to normal to prevent unauthorized personnel from loading a new
server BIOS.
5) Turn the power back on for normal operation.
