2.9.1 BIOS Setup Configuration Jumper Block
This 3-pin jumper block determines the BIOS Setup program’s mode. Table 46 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 CPU version and the microcode version in the BIOS and reports if the two match.
