On a side note, I quote your document:

--- quote --- 
GNU Mach labels IDE disks starting at zero as hdN, and SCSI disks as
sdN. However, like Grub but unlike Linux, the drives are numbered in
the order which they are found: i.e. not their position on the
bus. This is to say that if the only IDE disk on the system is the
secondary master, it is hd0.

However, the FAQ says something different (and I believe it is correct
here):

--- quote ---
First, figure out the disk number. If it is a SCSI disk, you need to
know the SCSI disk number. If it is an IDE disk, you need to know on
which controller it is and if it is a master or slave. For Linux, the
master disks on the primary controller has the letter "a", the slave
on the same controller the letter `b'. Master and slave on the
secondary controller have the letters `c' and `d' respectively. The
Hurd does use BSD style notation so it is `0', `1', `2' and `3'
instead `a', `b', `c' and `d'. This means /dev/hdc under Linux
translates to /dev/hd2 under the Hurd. Got it? Good. GRUB does it
differently! GRUB is doing it like the BIOS and enumerates all
installed disks it can boot from starting from "0" incrementing by
1. So `hd(0,?)' is a partition on the first disk it can boot from,
regardless if this is a master or slave or whatever. The second disk
it finds has `hd(1,?)' etc. Luckily, the BIOS is searching in the well
defined order primary controller master/slave, secondary controller
master/slave.

Should this be changed in the installation guide?
