Dual boots windows 98se and windows xp, specs are amd athlon xp 2600+ cpu at 2.09ghz, 1.5gb of ram with windows 98 memory patch, an ati radeon 9200 agp card with 128mb vram, sound blaster live 5.1 sound card, 38gb hdd for windows 98 and a 150gb hdd for windows XP. Has a front case fan and pc comes with driver/software cd and display driver disc, I didnt build this pc this is how i got it 7 years ago im not a very knowledgeable person when it comes to dual boot setups but everything has been working the time ive had it, sometimes id have to reload sound drivers on windows xp for some reason but thats why all original cd roms are included incase something happens. Some of the preloaded dos games dont run and some dont have music but the ones that did work all had basic sound fx.
