However, PnP BIOS information isn't the > same thing that the orm[sic] driver probes for. They look related. I've now found the orm output: orm0: <Option ROMs> at iomem 0xe0000-0xe3fff,0xdf800-0xdffff,0xd0000-0xd17ff,0xc0000-0xcefff on isa0 The last one is the video BIOS. It's interesting to note that it doesn't report the 4 kB BIOS at 0xcf000, which suggests that at this point the 16 kB area is already unmapped. I've worked around the problem by compiling the video BIOS into the X server and not trying to access the BIOS in the machine. Obviously not a solution, but it works for the moment. I'd really like to track down the problem. Does anybody have an idea? Greg -- See complete headers for address and phone numbers
