I know of a way to set the permissions through root user, but the ability to block files and directories is dependant on the person who created the file(s), so you are stuck if you are not the root user. Anyway, you set the permissions of any file (logged in as root user) by using the command:
chmod [options] (file)
where the options need to be looked up in the manual page because I cant remember them all, and file is obviously the name of the file you want restricted.
I assume that you know where the folder Win98 is mounted to?
If so all you need to do is set the permission in the folder it is mounted to. For a better explaination (cough) of this here is the link:
