Product :: VBE Grub
GRUB has some builtin VESA routines and the functionality to switch video modes using VESA 2+ BIOS calls but it currently has no way to set this video mode up and pass the information to the OS. As part of the multiboot standard, a multiboot kernel should be able to request the video mode it is booted up in and have video information passed to it.

GRUB 0.94
GRUB 0.97
Functionality
The changes to GRUB implement the following additional commands:
- vbematch – sets a video mode according to dimensions (height, width, depth)
- vbeset – sets a video mode according to VBE mode number
These commands override the requested mode of the multiboot kernel.
In addition to providing these other commands, the changes also implement the proposed VBE functionality of the multiboot standard. However, the commands given to grub (vbematch, vbeset) will override the kernel wishes.
Contributions
- Bryan aka Brynet actually took my original modifications to the GRUB source and converted them into a patch set AND got the patch into version 0.97 as well as the original 0.94. So, pretty awesome. You all should really be thanking him for this page. If you want to do so in person, contact me for his email address.
