I have it running in VirtualPox and I`d really love to get it to boot into a resulution that I can actually see without scrolling. Unfortunately the screen mode preferences seems completely broken.
If you really want to fix this on the bootmanager level you should be able to find some info through google: "GRUB" is also used on many Linux distributions and should be documented pretty well. The muliboot options are visible when you press e in GRUB, so you should be able to roll your own, but I haven´t tried any of this.
