and the other is JP8 (Flash ROM Type).
JP3: Clear CMOS Memory
The onboard CMOS memory is where the system con-
figuration information set by the BIOS Setup program is
stored. If you make entries in the Setup program that will
prevent the computer from booting up or you set a pass-
word and then forget it, you will not be able to use the
computer. If this happens, you must clear (erase) the
CMOS memory and enter new configuration informa-
tion in the BIOS Setup program. The BIOS Setup pro-
gram is covered in Section 3.
To clear the CMOS memory do as follows:
1. Remove the jumper cap from Pins 1&2
2. Place the cap over Pins 2&3 for five seconds
3. Replace the cap over Pins 1&2
When you are done, you can start up your computer and
run the Setup program to re-enter the system configura-
tion information. The location of JP3 is shown below.
