1. Follow the directions at http://www.raymond.cc/blog/
2. Extract the files in the following zip to the root of your thumbdrive:
3. Tell your BIOS to boot from a USB drive (F12 on most Dell's brings up this boot device menu).
4. When the syslinux menu comes up, choose "1st Kon-Boot" first and step through it.
5. The 2nd time the syslinux menu comes up, choose the option "2nd try boot from drive C: as hd1".
6. If hd1 does not work, try hd2 and so forth until you get in. If you have a a multi-boot system you may get a boot error, but it still worked for me after I confirmed past it.
7. On Linux login as kon-usr at the terminal (not GDM/KDM/XDM). On Windows use any valid local user name and a blank password (or even gibberish, anything you type in as a password seems to work).
Thanks to the Pauldotcom guys for letting me know about Kon-Boot.
