Anyone interested can review the slides I presented online at:

While I was concerned about not having enough material, in fact it
turned out that the reverse was the case, and I was forced to gloss
over quite a few topics including SysVInit scripts, and
Systemd/Upstart which of course are major new developments.  This
presentation was bound to never be more than an end-to-end overview,
but if anybody has feedback feel free to provide it and it will
benefit those attending at PLUG West/Central.

Some topics that came up during discussion that would make for
excellent future talks (for anyone who would like to give one)
Hardware detection / Hotplug / UDev / etc
Systemd / Upstart - either compare/contrast with SysVInit and each
other, or in-depth focus on one.
SysVInit Scripts in general

Thanks to the many who came out - hopefully everybody learned
something new before they bugger_off'ed.

And JP, thanks for keeping me honest on my MS-DOS claims.  I suspect
that you might have more success with a non-USB floppy controller
(physical or emulated), for the reasons you suggested.  Believe it or
not when you turn on your modern 64-bit PC the BIOS will instruct the
Northbridge to ensure that accessing address 1MB+1 goes to address 1
in memory, just as it would on an 8088 with only 20 physical address
lines but the ability to logically address ~20.09 bits.  And no, JP, I
have no idea whether Intel-based Macs gate A20...  :)
