I just plugged in an em(4) compatible card, powered it up and now my server works like a champ with the XP machine. As a reference the MB's affected by this are mostly the ASUS MB's, i.e. P5B and P5K series ones. MSI MB's may be affected by this issue as well because I think they come with msk(4) compatible chipsets onboard.. -Garrett
