This chapter provides jumper setting information for configuring the system for a particular
system requirement. Situations that require changing the jumper settings include the
following:

„
You have interrupted the Flash utility during a BIOS upgrade.

You want to clear all customized CMOS settings back to the factory defaults.
„
You want to deny access to the Setup utility.
„
You forgot the password and cannot boot the system.
„

only the setting for that condition. Otherwise,
keep the settings at their factory settings.
