4.4.2 Clear CMOS Jumper
Jumper Label: JP8
Jumper Type: 3-pin header
Jumper Settings: See Table 4-31
Jumper Location: See Figure 4–29
If the IQ7 Design Guide fails to boot due to improper BIOS settings, the clear CMOS
jumper clears the CMOS data and resets the system BIOS information. To do this, use the
jumper cap to close pins 2 and 3 for a few seconds then reinstall the jumper clip back to
pins 1 and 2.
If the “CMOS Settings Wrong” message is displayed during the boot up process, the fault
may be corrected by pressing the F1 to enter the CMOS Setup menu. Do one of the
following:
ƒ Enter the correct CMOS setting
ƒ Load Optimal Defaults
ƒ Load Failsafe Defaults.
After having done one of the above, save the changes and exit the CMOS Setup menu.
The clear CMOS jumper settings are shown in
