Anyone interested can review the slides I presented online at: https://docs.google.com/present/view?id=dkkx9dh_6d26244dd 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) included: Hardware detection / Hotplug / UDev / etc Grub2 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... :) Rich ___________________________________________________________________________ Philadelphia Linux Users Group -- http://www.phillylinux.org Announcements - http://lists.phillylinux.org/mailman/listinfo/plug-announce General Discussion -- http://lists.phillylinux.org/mailman/listinfo/plug
