Wow. Haven’t installed XP in quite a while. I installed the retail XP from a CD.
Then had to find my motherboard drivers on a different PC, burn them to a CD, since XP didn’t have the drivers on the retail disk. And the motherboard network chipset wouldn’t work until I got the new motherboard drivers.
Then I went to Windows Update. First I had to download and install a new Windows Update component. Then 16 security/critical patches. Then and only then was I allowed to download Service Pack 2, which takes a long time.
And after that reboot, another 85! patches waiting for me. And then I had to download sound card drivers, and nvidia drivers.
So … if you do this, be prepared for a lot of time spent babysitting downloads and installs.
