2-9.5 Jp11: VGA/AGP 4X Safeguard
1. Default Jp11(2-3 closed) is to disable safeguard against 3.3V AGP2X
card and allow booting system with either 1.5V on-board VGA or 1.
5V AGP4X add-on card. User can choose either VGA or AGP 4X as
t h e i n i t i a l d i s p l a y b y c h a n g i n g B I O S S e t u p ( s e e " P N P / P C I
Configurations " in BIOS Setup).
2. Jp11 at 1-2 closed is to enable safeguard against AGP2X card and
allow only 1.5V AGP 4X card to boot system. With JP11 1-2 closed,
system cannot boot with onboard VGA or AGP 2X card. In this case,
if user cannot boot with an AGP card inserted in AGP slot, it indicates
that the AGP card is a wrong one. The AGP card should be changed
to a 1.5V AGP 4X card for booting system.
Warning:
• If a 3.3V AGP 2X card is mistakenly inserted for booting the system, the
high voltage will burn the 1.5V circuitry on board. Never use a 3.3V or an
unknow AGP card on this mainboard.
