I've been reading up on AdvanceMAME, and I still don't see how it can be done.  I need to set up a standard arcade monitor on a PC without an ArcadeVGA.  Can it be done without having to wait to switch on the monitor after the 'vga' command is run in the autoexec.bat file?
I am trying to set this thing up as a DOS-based system. 
Can Scitech Display Doctor change the 'boot mode' to use a 15khz signal?  Is there some other way to do this?
