Gigabyte GA-8VT800 User manual

Whenyou installing AGPcard,please make surethefollowing
notice isfullyunderstood and practiced.IfyourAGPcardhas
"AGP4X/8X(1.5V)notch"(showbelow),please make sureyourAGP
cardisAGP4X/8X(1.5V).
Caution:AGP2X(3.3V)cardisnotsupportedbyVIAPT800.You might
experiencesystemunabletobootup normally.Please insertanAGP
4X/8X(1.5V)card
Example1:Diamond VipperV770 golden fingeriscompatiblewith
2X/4Xmode AGPslot. It can be switched between AGP2X(3.3V)or4X
(1.5V)mode byadjusting the jumper.The factorydefaultforthiscardis
2X(3.3V).
The GA-8VT800 motherboardsmightnotfunction properly,ifyou install
thiscardwithoutswitching the jumperto4X(1.5V)mode init.
Example2:SomeATiRage 128 Prographics cardsmade by
"PowerColor",the graphics cardmanufacturer&someSiS305 cards,
theirgolden fingeriscompatiblewith2X/4Xmode AGPslot, butthey
support2X(3.3V)only.The GA-8VT800 motherboardsmightnotfunction
properly,If you install thiscardinit.
Note:Although Gigabyte'sAG32S(G)graphics cardisbased on
ATiRage 128 Prochip,the design ofAG32S(G)iscompliance
withAGP4X(1.5V)specification.Therefore,AG32S(G)will work
fine withVIAPT800 based motherboards.
