hi. i've put an intel pro/1000 MT desktop NIC in an old xp home pc (p4, 2.6G Elitegroup p4vxad m/b). it connects fine at 100Mbps but when selecting 1Gbps it trys to connect and fails saying cable unplugged. initially it would crash the pc (sometimes). I've swapped slots twice (and ensured a different irq), deleted old hidden/removed NICs from 'devices', updated and backdated drivers, removed and re-installed it, tried it connecting thru a switch and directly to an xp pro machine and a freebsd machine, swapped 4 pair cables.
while it could be the card or a weird hardware clash, i'm hoping someone can suggest some way forward. the driver has lots of options of which i understand few... perhaps if i changed some settings it may help, but i don't understand what most of them are. settings include:
'adaptive interframe spacing', 'enable pme', 'flow control', interupt moderation rate', offload recieve and transmit ip and tcp checksums, 'QoS packet tagging' , recieve + transmit descriptors, wait on line and some otherbacis settings i understand. all are set to default.
can anyone who understand these things advise or suggest anything to try?
