Hi Thomas

One caveat (and possibly an aside) is;
That, if you run Win 2k, XP,, etc. on the same machine and have 
"pinball.sys" installed to give Windows access to HPFS partitions, the 
largest HPFS partition can only be a maximum of 8 GB. This is from 
various things I've read and experience with a variety of machines.
