> What do I have to put in the MemBase line? Someone with an ATI GX Mach64 2MB - ramdac ati68860 Rev B, and clock ati18818-1/ICS2595, reported that he used: 8MB Aperature at 0xa0000000 I think this is supposed to be listed in the XF86Config file as MemBase 0xa0000000 This is only an inference, not experience speaking. Good luck, Susan Kleinmann sgk@sgk.tiac.net
