Yeah, just a bit. :) It is I believe hd(0,1) to select the first partition of 
the first hard drive found (usually the ide0 master). Similarly hd(0,2) will 
select the second partition and hd(1,0) will select the 2nd hard drive found 
(which could be the slave drive on the first ide channel, or the master drive 
of the second ide channel). hd(0,0) selects the entire first disk. And the 
man pages are fairly complete.

IMO, the biggest plus is being able to edit the boot line at startup. Let's 
say you install a new kernel, but typo it's name in the grub config. At boot, 
just arrow to the image and press 'e' to bring up the boot commands for that 
image. Select the line that you want to change, press 'e' again, make your 
changes, then press 'b' to boot. No more rescue disks for a bad kernel 
install. :)

Quick note: if your root filesystem is journaled, you might want to boot with 
the 'rw' kernel option, as log replay on a read-only drive is a bad thing. :) 
Mandrake up to 8.2 doesn't add the 'rw' flag to the lilo/grub config when 
appropriate, and I suspect RH doesn't do it either, but please correct me if 
I'm wrong.
