I just came across this thread the other day, and am quite shocked that this has not been mentioned in the audio/video section, where 50% of the topics revolve around vga support. Much more talk and interest will be found from members there.
I created a topic mentioning this in the audio/video section, so hopefully more people will be aware of this.
And kudos for the great work, junkmonkey. These feature you have added to the vga bios (namely LBA48 and IGR support), are greatly appreciated.
