Re: could the OS damage a NIC ?

Thanks for your reply Bob,

Yes I did.. sorry... I should have said that in the first email...

All the cards I took out from that machine did not work in any other systems with different OSes after its trip in that server ! And
they don't look blown-up, no capacitors, resistors, etc look toasted...

I also tried into different PCI slots...and there are no other cards in it... so it cannot be an interference of some kind with
another card...
