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 12 shows the location of the jumper block. The jumper determines the BIOS
Setup program’s mode. Table 21 lists 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.
