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.

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.
