I have a PCI card with 2Mb memory which works just fine at 8bpp. It also worked with 1Mb - which brings me to another question... I added the extra Meg of memory to move up to 64K colours. In order to drive my GD5434 up to 16bpp, I must specify a 'Membase' option for the framebuffer base address. To quote the 'Readme'... With a card on the PCI bus, there is a PCI configuration register that holds the framebuffer base address. However, the driver currently does not read it out yet, so you'll have to specify the address with MemBase. On one system tested, it mapped at 0xa0000000, and it appeared addresses where assigned in 0x08000000 increments over the PCI devices. A program is most likely available to read out the PCI configuration. So, does this program exist? Alternatively, can I work out the info. I need from the boot messages? I see that... vga0 rev 142 int a irq ?? on pci0:18 pci0: uses 16781312 bytes of memory from f800000 0 upto f8ffffff. Any help is appreciated... I'm running 2.0.5-950622-SNAP on a Pentium 60 with 32Mb of RAM John -- "That was inedible muck, and there wasn't enough of it." Sir Henry Rawlinson.
