I just loaded XP Pro on my laptop system. The thing is, is it is a an old 166MMX PI, 72MB RAM (Type unknown), 4.3GB HDD, NeoMagic 1.5MB Graphics. Dell Latitude LM. XP Pro works great on it, no slower than it was before with 98SE, and the screen looks better. So far so good. I mean Hell, all I use it for is writing and bit of surfing and chatting. I just wanted to see if it would work and it DID!!!
