Gigabyte GA-8I845PE Pro User manual

Whenyou installing AGPcard,please make surethefollowing
notice isfullyunderstood and practiced.IfyourAGPcardhas
"AGP4X/8X(1.5V)notch"(showbelow),please make sureyour
AGPcardisAGP4X/8X(1.5V).
Caution:AGP2XcardisnotsupportedbyIntel®845(GE/PE)/845(E/
G)/850(E)/E7205 /865(G/PE/PL/P)/875P/848P.You might
experiencesystemunabletobootup normally.Please insertanAGP
4X/8Xcard.
Example1:Diamond VipperV770 golden fingeriscompatiblewith2X/4X
mode AGPslot. It can be switched between AGP2X(3.3V)or4X(1.5V)
mode byadjusting the jumper.The factorydefaultforthiscardis
2X(3.3V).The GA-8I845PE Pro(oranyAGP4X/8Xonly)motherboards
mightnotfunction properly,ifyou install thiscardwithoutswitching the
jumperto4X(1.5V)mode init.
Example2:SomeATiRage 128 Prographics cardsmade by"PowerColor",
the graphics cardmanufacturer&someSiS305 cards,theirgolden finger
iscompatiblewith2X(3.3V)/4X(1.5V)mode AGPslot, buttheysupport2X
(3.3V)only.The GA-8I845PE Pro(oranyAGP4X/8Xonly)motherboards
mightnotfunction properly,If you install thiscardinit.
Note:Although Gigabyte'sAG32S(G)graphics cardisbased on ATiRage
128 Prochip,the design ofAG32S(G)iscompliancewithAGP4X(1.5V)
specification.Therefore,AG32S(G)will workfine withIntel®845(GE/PE)/
