To recover from a corrupted BIOS
Notes:
„
To start the server into recovery mode, a memory DIMM module
must be installed in the first socket, and a floppy disk drive must be
installed.
„
The CMOS is not cleared when the system BIOS is updated.
1 Insert the BIOS update disk (NTRH8057) into the floppy disk drive.
2 Power down the server.
3 Remove the server cover and access the motherboard.
4 Move the Boot jumper (J1H1) to pins 10 and 11.
To determine the jumper location, see “Jumper locations and
settings” on page 228.
Note: The jumper connects pins 9 and 10 by default for normal
BIOS.
5 Power up the server.
Result: The server boots from the floppy disk and the BIOS update
begins automatically. A single high-pitched beep tone announces
the start of the recovery process.
6 Wait until the BIOS update is finished.
A successful update ends with two high-pitched beep tones.
A failed update is indicated by a long series of short beep tones.
These tones indicate that some of the BIOS files may be corrupted.
Three beeps indicates that the BIOS update disk is not inserted in
the floppy disk drive or is not bootable.
7 When the BIOS update is finished, the server restarts automatically.
8 While the server is restarting, remove the BIOS update disk from
the server’s floppy disk drive.
9 While the BIOS boot initialization screen is displayed, power down
the server.
10 Move the Boot jumper (J1H1) back to pins 9 and 10.
