Re: Guidance

[Andrei E. Warkentin]

My understanding, as a user of GRUB, was that GRUB relied on the  
system BIOS to perform any disk I/O, thunk to RM to invoke INT 0x13  
for all disk accesses.

Is the disk controller visible for the system BIOS? Can you boot off  
of it? Is there a bios disk number assigned to it? Does it  play nice  
with the BIOS Boot Specification or does hook INT 19?
