Forget the Inferno link as the P2DOS patch cannot be used in XP. The batch file needs to be modified for XP. You can find a version that will work in XP on The Sierra Help Pages. Also VDMS is a dead end program. It requires the heavily flawed NTVDM, which isn’t even included with many newer versions of Windows. Vlad Romascanu, author of VDMS, has abandoned it. DOSBox is, by far, the best solution.
