Nope. Even integrated Ethernet uses exactly the same protocols to work as the old 10Base-2 cards. The only difference is that instead of sitting on a card, the chip is on the mobo. They work exactly the same way.
Did you miss my post above about how I booted brand new hardware with a Linux OS from 2002 and everything worked?
Maybe they use the same stuff maybe not. Remember it’s not the communication with the outside world that matters, it’s the communication with the OS. If that guys network adapter doesn’t talk to the OS the same way network cards did 7 years ago then XP isn’t going to be able to handle it.
I saw that, and asked if it was the same adapter the guy had. If it’s not the same adapter then it means nothing.
