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 16 shows the location of the jumper block. The jumper block determines the BIOS Setup
program’s mode. Table 27 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.
