yeah i don't know if you can write to the hdd in the boot cd version (might be possible mounting the ntfs partition -- but this isn't recommended) mandrake 10 on a whole provides a much completer expierance than 9.2
both are 3 cd's as well, so no real gain or loss there.
if you are an australian resident and on telstra you have access to pretty much any linux distrobution on
http://files.bigpond.com./index.php
downloads from there come in at about 600k a second for cable but you probably aren't australian so it isn't much help to you but you might still be able to get files from there not sure.
