2.9 Jumper Block
CAUTION
Do not move any jumpers 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 13 shows the location of the jumper block. This 3-pin jumper block determines the BIOS
Setup program's mode. Table 51 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.
