2.8 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 23 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.
