Old 88800GX boards are powered on with disabled MMIO and this MMIO cannot be enabled through PCI, but must be enabled through io port 0x6AEC (and this effectively disables multihead). Another problem is that there are couple of DACs on these ATIs and driver supports only two of them - - IBM RGB 514 and ATI 68860 B... So unplug card from computer and look at it. If you'll find 'CH8398' on the board, try patch ftp://platan.vc.cvut.cz/pub/linux/2.3.5/atyfb.gz (as path indicates, it is for kernel 2.3.5. I throwed device away after that and replaced it with yet another matrox). It worked for me in the intel box... Best regards, Petr Vandrovec vandrove@vc.cvut.cz
