If I do not use /smp it will boot. with /smp if use /pic I can boot to the start of the desk top. Crash requires reset. CAD will not work. with /apic the crash is at loading either hpfs or jfs, whichever is first, requiring reset. In both cases there is no pop-up or system message. I have seen in some of the forums other users are also having problems. Hopefully this may help get the nvidia boards running. Ben " defect closed major ACPI PSD 3.02 fixed
