>Description:
The computer is an old-fashioned dx2/66 eisa pc.
Allocation of io-port-range fails for parallel port on an old
monochrome graphics card.
>How-To-Repeat:

>Fix:
Either change the port allocation function in the parallel driver to
only allocate 4 ports (which I did for this specific machine) or
create a new flag for that driver.

 Hello Sheldon.
 I do not know how much of my problem report appeared in the public. But I
 found solutions for
 both problems I described.
 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. Allocation of
 4 addresses works.
 Bye
 Norbert.

 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...
