Reverting to the Previous BIOS

If you encounter a problem with your BIOS, you may want to revert to the previously
installed BIOS. Because of the rolling BIOS feature, your workstation contains two
versions of the BIOS: the current BIOS, and the BIOS that was previously installed.
Note: If you upgrade the BIOS more than once with the same BIOS version, the two versions of
the BIOS stored in your workstation will be identical.
To revert to the previous BIOS:
1. Power down the workstation and disconnect the AC power.
2. Remove the chassis cover. For instrucstions, see
page
3. Locate the BIOS Bank Select jumper at board position J1C3. See
4. Move the jumper from the normal operation position, covering pins 2 and 3, to the
Bank_0 position, covering pins 1 and 2, as shown by the diagram.
