  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 3-pin jumper block determines 
the BIOS Setup program’s mode. Table 25 describes the jumper settings for the three 
modes:  normal, configure, and recovery.
