5. Insert the bootable BIOS recovery diskette that contains the BIOS update files.
6. Replace the AC power cord and turn on the system power.
The recovery BIOS boots from the recovery diskette and emits one beep when it passes control to
DOS. DOS then executes a special AUTOEXEC.BAT that contains “iFLASH” on the first line. If
it is determined that the system is in recovery mode, iFLASH will start the flash update without
user intervention.
iFLASH reads the flash image and programs the necessary blocks. It emits one beep to indicate the
beginning of the flash operation. After two to four minutes, the BIOS emits two beeps to indicate
that the flash procedure was completed successfully. If the flash procedure fails, the BIOS emits a
continuous series of beeps.
When the flash update completes:
1. Turn off the system power and remove the AC power.
2. Remove the recovery diskette.
3. Restore the BIOS recovery jumper to its original position, covering pins 9 and 10.
4. Close the server chassis.
5. Replace the AC power and turn on the system power.
6. Re-flash any custom blocks, such as user binary or language blocks.
The system should now boot normally using the updated system BIOS.
