Thanks to everyone who is providing input on this question. I appreciate it greatly! :) The boot loader idea sounds like it'll have to be what I use. I'll get the CD to write a token to the drive if it checks out, and upon next boot-up, if I can get the CD's boot loader to find the token on the HD, it'll boot the HD instead. Any ideas on how to arrange that one? If I can't get the boot loader to do that, I'll have to resort to making the partition bootable/unbootable to make the selection; although I'd prefer the token. I do agree that one of the best ways to secure the box is to use the secure levels and mount things read-only. I will be doing that, but my goal here is to remove every remote possibility of my machine's compromise lasting beyond a day. I like to go for absolute certainty on security. :) Thx --- "Theodore K.
