2.9.2 BIOS Setup Configuration Jumper Block

The 3-pin jumper block determines the BIOS Setup program’s mode. Table 29 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.
