BIOS configuration jumper settings

    The BIOS configuration jumper lets you clear passwords or recover your BIOS if it becomes corrupted. For information about the location of this jumper, see Section 1.

Setting Jumper placement When used

Normal

For normal operation. The BIOS uses current configuration information and passwords.

(1-2 position)

Configure

For clearing passwords. The BIOS Setup utility runs automatically and the Maintenance menu is displayed.

(2-3 position)
