Recovering From Corrupted CMOS and BIOS
If the system behaves 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 HMS 400 server can
start in recovery mode. To boot in recovery mode, follow the procedure in “To recover from a
corrupted BIOS”.
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 145
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.
10.
For instructions, see “To configure the BIOS” on page 144.
