I have a Pentium3 900mhz with 256 ram but thats my main computer so im not even letting XP near it, also got a pentium3 700Mhz laptop it ain't going near that either.
what i did try to install it on was a pentium1 200mhz - compatibility check showed problems so i took it out.
I have way to much data on my other machines to even attempt to put XP near it all the data is backed up, but who needs the headaches? I went thru that with win me and that was a final release!! what a piece of shit that is.
