[Good CD/CDRW/DVD/DVD-+RW boot faq]

Can anyone provide a quick, concise, explanation of how a CD-ROM or DVD-ROM reader or writer, requests and discerns boot information/media descriptor info from all the various CD-DVD bootable formats.

How many different media are rocognized as bootable? How do the boot sector differ?

[Is there a way to "save" IE6 proxy config?]

I'm sure this must be an everyday thing to business PC users who have XP machines that log in remotely to domains.

Is there a way to save a given set of security zone settings AND proxy server configuration in IE6? So that a user could run an IE6 session without going through corporate servers and VPN client, etc......

I know how to switch out of the IE6 proxy configuration, but, I wan't to make sure I can restore it.... when finished.

Thanks.
