all you need off the 95osr2 cd is the "win95" directory off the cd (about 100 megs max i think)...you just run setup from that directory if you have it, and yer good to go..plus if you install off that directory, it will never ask for the cd when you need to install windows components because it will just look there.
but legality is the key here, and sounds like you're gonna hafta wait to get the cd....but in the future you could copy that "win95" directory from the cd to your hard drive so you don't run into this problem again.
btw...the most common place to copy the contents of that "win95" directory on the 95 cd is to a folder you make called "c:/windows/options/cabs" (at least, that's the most common place to put them)
