Hi Jamie,

Thanks for pointing out the problem, we'll be able=20
to investigate it further with the info you provided.

For 800x600 and 1024x768 modes, if you compile in vbe
support, you'll be able to install our svga driver
available from our sourceforge file area, bochs-tools.iso
(cdrom image) or bochs-tools.img (1.44 floppy).
800x600 and 1024x768 in 8bpp modes will be available.
