How do I use my ATI Graphics Xpression card?
That depends on which variation of the Xpression card you have. ATI has used different RAMDACs on different revisions of this card. If you have an earlier revision (such as those with the STG1702, STG1703, and CH8393 RAMDACs), it should work without problems with the current release (3.1.2). If you have one with the AT&T 20C408 RAMDAC, see item F22 as well as section G. If you have one of the new “CT” versions, see item F18.
