BIOS Select Jumper: BIOS_SELECT
The jumper is used to select a BIOS
ROM to boot from. You can refer to
the following table for reference.
How to recover BIOS
When one of BIOS has been dam-
aged, you can use another work-
able BIOS to boot to DOS.
Then switch the jumper to change
to your bad BIOS.And then run the
“AFUDOS” reflash program.
Discharge Battery Jumper: VBAT_DISCHARGE
Resetting the CMOS isn’t always good enough since in more recent chipset versions some
configuration settings stored in the Southbridge will not be reset or deleted by a CMOS reset.
Additionally the CMOS reset can take up to several minutes depending on the board design and
capacitance. To facilitate a complete configuration reset this jumper can be used to discharge the
battery. The effect is identical to removing the battery. The result is a faster and complete CMOS
and Southbridge configuration reset.
