Jumper
Clear CMOS Jumper: JBAT1
There is a CMOS RAM onboard that has a power supply from external battery to keep
the data of system configuration. With the CMOS RAM, the system can automatically
boot OS every time it is turned on. If you want to clear the system configuration, set
the JBAT1 (Clear CMOS Jumper ) to clear data.

Important
You can clear CMOS by shorting 2-3 pin while the system is off. Then return
to 1-2 pin position. Avoid clearing the CMOS while the system is on; it will
damage the mainboard.
BIOS Recovery Jumper: J4
A "boot block" program is included as part of the system BIOS to recover the system
from a situation when the BIOS code is incorrect/corrupted or needs to be updated.
W hen the BIOS code is corrupted or needs to be updated, you have to at first enable
the boot block by short connecting pin#2-3 of the J4 jumper. Then the boot block will
try to recover the BIOS code, usually by reading it from a specially-prepared floppy
disk.
Under normal operation, we suggest that you disable the boot block by short con-
necting pin#1-2 of the J4 jumper to protect the boot block from virus infection.
