For reference, part of this is documented in the FAQ, under "for hackers only" http://www.freebsd.org/FAQ/hackers.html#AEN4419 To quote the interesting part of it: "Microsoft took over some of the primary printer status ports to do PnP, on the logic that no boards decoded those addresses for the opposing I/O cycles. I found a genuine IBM printer board that did decode writes of the status port during the early PnP proposal review period, but MS said ``tough''. So they do a write to the printer status port for setting addresses, plus that use that address + 0x800, and a third I/O port for reading that can be located anywhere between 0x200 and 0x3ff." Of course, no-one should be using a 19 y/o video card in a recent machine in MS's eyes...it can't run Windows 95 after all... > For the dx50: Installation fails because of pnp-scanning of port 3c3. > Without pnp-scanning it works. > For the eisa/dx266: Allocation of 8 io addresses at 3bc fails.
