I'm seeing it a bit different
in case there are no hardware troubles, and mistakes,
IRQ sharing is good for linux but not for windo$e
some time ago i had two free PCI slots and i bought a TV card, every
try to install the drivers for win9x causes total freze
there was no way to install winNT or 2k with the card pluged, but after
instaling the ?OS? no troubles instaling the card
but with linux not a little trouble
and now i use all the PCI slots regarding the fact that one shares IRQ
with the AGP bus, one with the on board HPT366 controler,
and one with the USB
it would be a wonder , if possible to install winxx on such a PC
and linux works wonderfully
