Adding a 2nd network controller cause WinXP not to start!!

Hi. I have tried this with 3 different PCI ethernet cards and it's always the same.

Having just one PCI ethernet card on my WinXP machine works great. When I add a second one however, it causes Windows not to start.

Any ideas why this is happening? I would really appreciate any help on this.

Thanx!

Try disabling the boot to network option in the BIOS.....

At what point does it stop booting?

which slots are the two nic's in?
