More minor updates to release notes -- a large part of these changes were
sgimips specific, but there are also MI tweaks.

This is a complete refit of the mac68k documentation.

Of particular note is documentation on the new preferred method of
installation using sysinst, provided (and updated) by Bob Nestor.

Update sgimips portions of release notes to more closely match reality, esp.
after the removal of the kern-GENERIC set from sysinst. While here, fix up
some minor things (wording, bad markup, typoes) in the non-sgimips specific
common portions.

remove info that's not relevant for 1.6

_ copyright crank
- whitespace cleanup
- formatting cleanup (start sentences on new lines)

Adapt for the atari. Also add some braces to make the if-switch do what I
think it should do.

branches: 1.13.2;
Purge mentions of NetBSD/arm32.

Describe how to install onto a drive that will also be used by MacOS (such
as most of the post-1998 models).

Also reminder about reversed MAC address on early models (macppc/install).

We can now do upgrade by using sysinst.

Update copyright date.
Colons after text before examples.

don't claim the old /etc configuration is merged in, 'cause it ain't so.
noted in pr 9662.

postinstall: add conditionals for hp300, macppc, and sparc

sysinst: tsubai-san says that macppc doesn't suffer from install-related
pcmcia interrupt problems. removed those for macppc

upgrade: add conditional for macppc and sparc (don't need to boot
from floppy)

more cleanups
- use .Ic, .Pa, .Key, .Ul, .Tn, .Sq, .Dq as appropriate
- use .Dl instead of .(disp when formatting changes are required (the latter
doesn't cope too well when font change macros are used)
- wrap .Dl blocks with .Pp
- consistently use `file system' instead of `filesystem'
- migrate macppc to common/xfer

use the macros from ../common/macros

update copyright date

Missing `the'. Pointed out by jhawk.

X68k now uses sysinst.
Also update reflecting the current version.
More cleanup is needed before pulling it up to netbsd-1-5.

branches: 1.2.8;
The pmax needs to upgrade bootblocks before booting the install kernel.
And don't mention those darn floppies...

branches: 1.1.2;
Give the common install notes components their own subdirectory.
Also, alpha and i386 now use a single merged common/sysinst,
and arm32 and sparc have a single merged common/xfer.
