System Recovery

Loading Default BIOS Settings

The default BIOS can be restored either by using the “Load Defaults” option in the BIOS, or by installing jumper JP5 (see Figure 6 on page 81). In most cases, the easiest way to load default settings is by setting them in the BIOS. For other unique cases, jumper JP5 provides an alternative method of restoring the BIOS settings.

To restore the default BIOS settings with jumper JP5, follow the procedure below.

1.Remove power from the system.

2.Install JP5.

3.Apply power to the system. The cpuModule will then load its default settings. Note that the multi-color LED will be red if power is applied while JP5 is installed.

4.Reboot and press Delete to enter BIOS Setup.

5.Save the BIOS settings and exit, allowing the system to boot to the FSBR.

6.The next time the system is powered, the BIOS Setup will be configured to use the default settings.

Booting to the Fail Safe Boot ROM (FSBR)

If your system is in configuration that will not allow it to boot, the Fail Safe Boot ROM is a minimal build of ROM-DOS which can be booted to for system debugging. To boot to the FSBR, follow the instructions below.

1.Remove power from the system.

2.Install JP5. This will force the cpuModule to boot using the default BIOS configuration.

3.Apply power to the system. The cpuModule will then boot to the Fail Safe Boot ROM image. Note that the multi-color LED will be red if power is applied while JP5 is installed.

4.Press the {Del.} key to enter Setup, or allow the cpuModule to boot to Failsafe
