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 24 shows the location of the jumper block on the D915GAV board. (The jumper is in the
same location on the D915GAG board.) The jumper block determines the BIOS Setup program’s
mode. Table 38 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.
