I am using Workstation 7 (no ACE options enabled) and was able to have my MS-DOS VM come up full screen by doing the following:
Edit the virtual machine settings
Click on the options tab
Click on power settings (in the left hand screen)
Click on 'enter full screen mode after powering on' under the power options (in the right hand screen)
The next time I start the VM, it is in full screen mode.
If I remember ACE correctly, you could then build a package based on those settings which should work.
good luck.........Bruce
