2.3 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 26 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.
