Ah, vinfo /m puts "machine type" into DOS %errorlevel% variable. Entered towards the end of my C:\FDAUTO.BAT file. Might be a good idea for initial debugging, using the following: echo %errorlevel% Reports 6 (vinfo /? -> 8086 or better) for a Dell Optiplex 755 Reports 102 (obviously) for Qemu. Works using within FDAUTO.BAT on my FreeDOS-1.4 install onto USB flash media. Now for removing evil goto... ;-) Roger
