Using GRUB's raw IO interface

[Scott Powell]

Hi all,

I'm looking to use the raw IO functions of GRUB for a project I'm working on 
(GPL'd of course). I've trimmed down bios.c and disk_io.c to the point where 
they contain only the functions I need, but I'm still having a little bit of 
a problem with asm.S. I noticed that there's a separate INT13 handler 
included to do some kind of drive mapping, but I don't know enough about 
low-level IO to know if that's necessary or not for my purposes.

Basically all I want is the ability to write an obscene amount of data to a 
partition. Do I need this INT13 handler, and is there any other 
functionality I'm going to need from asm.S, aside from 
real_to_prot/prot_to_real/get_diskinfo/check_int13/biosdisk?

Thanks in advance for any information you can give me,
Also if you know of any raw IO library I could use instead, I'd be grateful.
