On the VIA chipset there is an option called 'Delayed Transaction'. This option
causes some network adapter not to work correctly. I have seen this on some
Athlon boards using KT133 or KX133 chipset, but I think this might be the case
on the Apllo chipset for PIII too. Take a look in your bios for a possibility
to turn it off.
