please explain to me why video/bios shadowing must be disabled to use graphics...
Hello.

your problem is mostly not video shadowing
I tried this privately already - doesn't work:)

but just that DOSEMU does
not support this video card and does not open up enough ports.
Note however that this must not be the case for VGA modes.
And esp. if the person have a terminal chars in a dos box (which most likely means that the video bios was not even mapped in), yet have a text-based progs working.

ports it tries to access and dosemu doesn't understand. You can enable then in the "ports" section.
If someone could explain why this method works no more with the modern cards, I would be very happy. What you now get opening these ports, is a hard lock-up:(

Stas tried hard to get
DOSEMU working on his ATI Radeon, and Vesa modes do not work for him.
But not all hopes are lost here: now XFree 4.2 can set any vesa mode on my Radeon, while 4.1 couldn't. So at least now I know that getting VESA to work again is somehow possible, probably by stealing some code from XFree.
