Jumper Block

CAUTION
Do not move the jumper with the power on. Always turn off the power and unplug the
power cord from the computer before changing a jumper setting. Otherwise, the
board could be damaged.
Figure 14 shows the location of the jumper block. The 3-pin jumper block determines
the BIOS Setup program's mode. Table 34 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.
