It was on a much older generation of equipment, where we were
discovering that the BIOS couldn't access the full 32G Compact-Flash
card we were trying to use, but on this particular box I was able to use
"ls (hd0)" at the grub prompt to see grub's idea of the size of the
device (which presumably was based on the BIOS's access limits):
====
grub> ls
(hd0) (hd0,msdos5) (md0,msdos1)
grub> ls (hd0)
Device hd0: No known filesystem detected - Sector size 512 - Total size
8257032KiB
====
Since 8257032KiB is nowhere near 32G, we figured the BIOS couldn't
access the full disk (and so we used a small /boot partition to do the
install).
(In the context of your discussion, I guess you would need to do this
test from a grub that is *not* using the native grub device drivers.)
