2.9.1 BIOS Setup Configuration Jumper Block
This 3-pin jumper block determines the BIOS Setup program’s mode. Table 49 describes the
jumper settings for the three modes: normal, configure, and recovery. When the jumper is set to
configuration 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.
