Changing Hardware IRQs, not rerouted by Windows or BIOS, could fix some problems. I was just asking if he did . Jup, those 3com 90x card are good for just the basic stuff now, I use them to install XP on systems without a NIC or a NIC that requires an extra driver. Those Broadcom chips are not bad at all, first time I used them was on an A7V333 or so from ASUS. Are you sure that it works on the PCI-E (1x) bus?
