2.9 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 19 shows the location of the jumper block.  The jumper block determines the BIOS Setup 
program’s mode.  Table 28 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.
