Geert, Pete, Thanks for your input, it makes me question things I should have questioned before. 0xC000 0000 is the actual address I am trying to use. I used it because another PCI card that I have a driver for was using it and so I just carried on its use. I didnt really question the value or its use. But obviously it works for that card. After your emails I revisited that code and now I partially understand why it works. The chip has an internal bus that translates address requests internally. So when i write to 0xC000 0000 it would never make to the actual address lines of the chip and instead be routed to the PCI controller ( I think :) ) The original card i had a problem had an ATI Rage chip. I am now experimenting with a VGA card with a Cirrus Logic chip. I've got this card to accept the programmed base address and am in teh process of studying clgenfb.c to see if I can modify it to my needs. On first inspection clgenfb.c is written for the Amiga??? and so I am trying to weed out the dependencies. If anyone knows of a more generic driver it would be much appreciated.
