System BIOS Recovery Procedure (8650)
System BIOS Recovery Procedure

not screen display, you will need to listen for the following audible
status signals.

Continuous series of low beeps (like a buzz) |
Any or all of the following causes: ° The wrong BIOS recovery files are being used ° Configuration switch allowing BIOS Recovery mode is in the wrong position. ° Configuration switch allowing BIOS Write to flash memory is in the wrong position. ° One or more system BIOS FMUP files are corrupt or missing. |
NOTE:
If the BIOS of an add-in board is mapped to any part of the E0000H
range, you must either map it to another area before beginning a recovery
procedure or physically remove the board from the system.
To run the BIOS recovery procedure, do the following.
- If you have not already done so, copy the BIOS Update diskette
files to a bootable DOS diskette.
- Power-off the system.
- On the system board, move the J6A1 BIOS Recovery jumper from pins 1 and
2 to pins 2 and 3. See 'BIOS Recovery Jumper (J6A1)'.
- Insert the Flash Memory Update diskette (the bootable DOS
diskette you copied the update files to) in drive A, then, power-on the
system. You will hear a single initial beep that is part of the normal
system start-up process.
- You will hear two beeps when the process is successfully completed.
If the process is not successful, you will hear a different beep pattern.
Refer to the preceding table.
- Make sure the diskette drive activity light is off. Power-off the
system.
- At J6A1, remove the BIOS Recovery jumper from pins 2 and 3, and place
it back on pins 1 and 2.
- Remove the FMUP diskette from drive A.
- Power-on the system and check the BIOS version number against what you
intended to flash in.
