BIOS calls in Grub

[Adam Agnew]

Hello! I am exploring using Grub in conjunction with LinuxBIOS
(www.linuxbios.org). But in order to do so, I would need to take out the
code in Grub which depends on a legacy BIOS (for such things as INT13) and
replace it with code which does not. Some work along these lines has been
done in Tiara (sourceforge.net/projects/utcboot) but I believe their code
has solved this issue by supporting these BIOS calls through freebios
(freebios.sourceforge.net). That's not a viable answer for my project, and
they are also adding a forth compiler in the mix, which is not desired.
What I'm wondering is if there are any experts here who could point out
such BIOS calls in the Grub source for me (which I am not as familiar yet
as I would like to be) so I can determine the extent of the work that this
would entail. Thank you very much for your time.

Sincerely, Adam Agnew
