install-doc: [MIPS] missing module/configuration information. (fwd)

I thought members of this list might like to review/expand/correct the bug
report on the debian installation guide I just submitted, based on my
experiences installing on an SGI Indy.

Subject: install-doc: [MIPS] missing module/configuration information.

Package: install-doc
Version: 3.0.23
Severity: normal

I just installed Debian/MIPS/stable on an Indy (then upgraded to
unstable, which was an adventure for another bug report).

It would be helpful if the installation manual mentioned in the
'modconf' section that 'hal2' (which uses 'soundconf') is the
module providing sound support on the SGI Indy.  You probably
also want to add users to the 'audio' group.

For X configuration, the driver to use on the Indy is 'newport'.
The best information on X-on-Indy (and Indigo2) is:

In the partitioning section, a sample disk partition would be
extremely useful.  For my system:
indy# fdisk /dev/sdb

Command (m for help): p

Disk /dev/sdb (SGI disk label): 66 heads, 62 sectors, 1008 cylinders
Units = cylinders of 4092 * 512 bytes

----- partitions -----
Pt#     Device  Info     Start       End   Sectors  Id  System
 1:  /dev/sdb1  boot         5       928   3779541  83  Linux native
 2:  /dev/sdb2  swap       929      1007    324735  82  Linux swap

11:  /dev/sdb4               0      1007   4124736   6  SGI volume

Bootfile: /unix

 1: newlinux   sector 3973 size 2627527

Command (m for help): q


The information I needed (which the manual did not explain) were:
 a) partitions start at 1, despite the special 'volume header' 
    partitions at 9 and 11, and user partitions 'overlap' with
    9 and 11 in a way that's best shown by example above.
 b) It's not enough that the swap partition be named 'swap', it
    must also have type 82. [I was misled here by installing
    Debian/PowerPC immediately prior.]
 c) It doesn't matter that the 'Bootfile' parameter doesn't match the 
    name of the boot kernel.

I forget if the manual includes sufficient information on dvhtool, but
a sample invocation can't hurt if it's currently missing:
 indy# dvhtool -d /dev/sdb --unix-to-vh /boot/vmlinux-2.4.22-r4k-ip22 linux

Finally, I found the following information on the Indy's boot prom
 IRIX manual on the use of the PROM:
 Resetting a bad ethernet address in the PROM (caused by dead batteries, etc)

 Proper PROM boot options for linux:
In particular, for my case (booting off sdb1, scsi id 4; note that 
partition(8) corresponds to what fdisk called partition 9):
   setenv OSLoader linux
   setenv SystemPartition scsi(0)disk(4)rdisk(0)partition(8)
   setenv OSLoadPartition /dev/sdb1
   setenv OSLoadOptions ""
where OSLoadOptions contains the linux boot arguments, if any.

Hopefully this information will help future Debian/MIPS installers.
