I have a via pc2500 mobo with that same chipset, afaik... I bought it very cheap thinking that it would be a great plan 9 machine but I was not able to install it because the ide/sata controller did not seem to be recognized by plan 9. I was using two sata disks at that moment.
Perhaps I should try again. I'll tell you how it goes...
