BIOS Setup Configuration Jumper (J6J2) Settings
The 3-pin jumper block determines the BIOS Setup program's mode. The table below describes
the jumper settings for the three modes: normal, configure, and recovery. When the jumper is
set to configure mode and the computer is powered-up, the BIOS compares the processor
version and the microcode version in the BIOS and reports if the two match.
