8. Close the server chassis.

9. Power up the server. The password is now cleared and you can reset it by going into

the BIOS setup. The BIOS password is now cleared.

8.3 BIOS Recovery Mode (J1C3)

The Intel

Server Board S5500WB uses the BIOS recovery to repair the system BIOS from

flash corruption in the main BIOS and Boot Block. This 3-pin jumper is used to reload the

BIOS when the image is suspected to be corrupted. For instructions on how to recover the

BIOS, refer to the specific BIOS release notes.

8.4 Reset BIOS Configuration (J1B4)

This jumper used to be the CMOS Clear jumper. The BIOS has moved CMOS data to the

NVRAM region of the BIOS flash since the previous generation. The BIOS checks during

boot to determine if the data in the NVRAM must be set to default.

8.4.1 Clearing the CMOS

1. Power down server. Do not unplug the power cord.

2. Open the server chassis. For instructions, refer to your server chassis

documentation.

3. Move the jumper (J1B4) from the default operating position, covering pins 1 and 2,

to the reset/clear position, covering pins 2 and 3.

4. Wait five seconds.

5. Remove power cable.

6. Move the jumper back to default position, covering pins 1 and 2.

7. Close the server chassis.

8. Power up the server.

The CMOS settings are now cleared.

Note: Removing power before performing the CMOS Clear operation causes the system to

automatically power up and immediately power down, after the procedure is followed and

power is re-applied. If this happens, remove the power cord again, wait 30 seconds, and re-

install the power cord. Power up system and proceed to the <F2> BIOS Setup Utility to reset

the preferred settings.
