Re: Compact flash and 'GRUB GRUB'

[MAL]

I'm sorry for replying to my own post, but I have found a solution in a 
way I did not expect to work, (or indeed understand why it does).

First i'd like to point out that I wrote two lines wrong in my previous 
mail.  These lines:
> root (hdc,0)
> setup (hdc)
were actually:
root (hd2,0)
setup (hd2)

Now, the solution.  Running:

setup --force-lba (hd2,0)

Worked.

I do not understand why, as every documentation I have read states that 
the compact flash should be dealt with in CHS mode.  The BIOS is set to 
use CHS, Linux uses raw CHS values, and so I would assume that is how 
grub should treat it!

If anyone can enlighten me on this, it'd be much appreciated.

Cheers,
MAL
