Request for assistance

[Mark Glassberg]

I have an AST Advantage! NB 486SX/33.  I am using linux and X Free 86.

I am also using the dosemu DOS emulator in order to run DOS programs
in an X window or virtual console.  I cannot, however, run DOS programs 
which involve graphics unless I use an external monitor.  It seems 
that the linux kernel does not recognize the ALT-CTL-@ keystroke 
combination for switching between video options.

I have been trying to get help from the dosemu project for some time, 
without success.  Any assistance would be greatly appreciated.
