Intel Desktop Board DG33BU Technical Product Specification
2.3Jumper 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 13 shows the location of the jumper block. The jumper determines the BIOS Setup program’s mode. Table 24 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.
