This makes me remember: If a VGA cards is jumpered or uses for some reason
a 16 bit ROM-BIOS access, this ROM takes 128kB of address space! This
has to do with address decoding on the AT ( ISA ) bus. So what may be:
On Netware they use only a 8 bit memory access and can deal then with only
16 kB address space. The Unix or OS/2 drivers use real 16 bit access and
therefore the cards takes 128kB away.

( I have such a card in my Novell server, the booklet says the very same )
