JP5: BIOS Boot Block Protection
This jumper protects the BIOS Boot Block from
accidental damage. If there is a failure when in-
stalling new BIOS, the protected setting allows
you to boot from a bootable floppy disk with the
Flash utility and BIOS file on it and install new
BIOS. Note that when the jumper is set to the pro-
tected setting, the BIOS Boot Block is not updated
when installing new BIOS. This may cause a small
degree of malfunction once the new BIOS is in-
stalled. We do not recommend changing the de-
fault. The default setting is Unprotected.
JP11: CPU & External Clock Frequency
This jumper sets the external clock frequency used
to set the CPU’ s operating speed. The Auto de-
fault setting will detect the necessary speed for the
installed CPU. All Celeron CPUs are specified to
use the 66MHz setting. You can also manually the
clock speed to 100MHz or 133MHz. The default
setting is Auto.
JP8: TV-Out Mode
This jumper is only present on the BIW2A-AT. It
sets the TV system mode used by the TV-Out fea-
ture. The jumper must be set to use the mode used
by televisions in your country, either NTSC or
PAL. The default setting is NTSC.
JP13: Onboard Creative Audio
This jumper is only present on the BIW2A-AT.
The jumper enables and disables onboard audio
for the Creative audio chip. The default setting is
Short, which enables the Creative chip.
