Interesting. I have been using lots of Intel cards and I have never had 
any problems of any kind. All of my cards are either onboard on Intel 
motherboards or Intel brand cards. I have also been using the Intel 
10BT/100BTX PILA8472C3 PRO/100 S Dual Port server adapter. It has 
worked very well also. The machine with the dual port card is my 
firewall for my whole network and has been running rock solid for a 
long time. I have not used them with anything past 5.0 though. I tried 
all four ping combinations and they all work fine on the cards I tried.
