I\'m using Xp and GigaStudio 160 without problems. First with a PIII 512 Ram, now I\'m trying with an Athlon xp 1600 1 gig..
Generally the problem are with drivers and motherboard incompability issues, I remember I had a lot of problems with a PIII 833 with Gigabyte mobo. My problems was compatibility with midi interface and audio card. I change to my old PIII (different mobo) wih the same Midi interfase and audio card and all work ok.
