When you installing AGP card, please make sure the following
notice is fully understood and practiced. If your AGP card has
"AGP 4X/8X(1.5V) notch"(show below), please make sure your AGP
card is AGP 4X/8X(1.5V).
Caution: AGP 2X card is not supported by SiS
experience system unable to boot up normally. Please insert an
AGP 4X/8X card.
Example 1: Diamond Vipper V770 golden finger is compatible with 2X/4X
mode AGP slot. It can be switched between AGP 2X(3.3V) or 4X(1.5V)
mode by adjusting the jumper. The factory default for this card is
2X(3.3V). The GA-8S648(-L) (or any AGP 4X only) motherboards might
not function properly, if you install this card without switching the jumper
to 4X(1.5) mode in it.
Example 2: Some ATi Rage 128 Pro graphics cards made by "Power
Color", the graphics card manufacturer & some SiS 305 cards, their
golden finger is compatible with 2X(3.3V)/4X(1.5V) mode AGP slot, but
they support 2X(3.3V) only. The GA-8S648(-L) (or any AGP 4X only)
motherboards might not function properly, If you install this card in it.
Note : Although Gigabyte's AG32S(G) graphics card is based on
ATi Rage 128 Pro chip, the design of AG32S(G) is compliance
with AGP 4X(1.5V) specification. Therefore, AG32S (G)will work
fine with SiS
648 based motherboards.
