Recovering from corrupted CMOS and
BIOS
If the system functions abnormally (for example, it does not start up or it
freezes during the startup process), the CMOS may be corrupted. To
correct this, follow the procedure in “”To recover from a corrupted
CMOS”” below.
In situations where a BIOS is corrupt or a BIOS update is not successful,
the 703t server can start in recovery mode. To boot in recovery mode,
follow the procedure in “To recover from a corrupted BIOS” on
page 227.
To recover from a corrupted CMOS
1 Power down the server.
2 Remove the server cover and access the motherboard.
3 Move the CMOS Clear jumper (J1H1) to pins 2 and 3 (by default,
the jumper is set to pins 1 and 2).
To determine the jumper location, see “Jumper locations and
settings” on page 228.
4 Power up the server.
Result: A message appears stating that the CMOS has been
cleared (reset to factory defaults).
5 Power down the server.
6 Move the CMOS Clear jumper (J1H1) back to pins 1 and 2.
7 Replace the server cover.
8 Power up the server.
9 Perform CMOS setup.
For instructions, see “To configure the BIOS” on page 224.
