What you do get are four *slices* (called primary partitions in the DOS world). Each of these is capable to hold seven FreeBSD filesystems. Even with the old 2GByte limit this should be more than sufficient. And this limitation was present at 4.2BSD ;-) (But then, my Ultrix-driven DECstation only has one slice per disk, so it is limited to 7 filesystems per disk) I don't see a reason you should not be able to have a huge data partition. Scalability of Unix fs's is much better than M$-crap. Greetings, Ripley -- H. Eckert, 10777 Berlin, Germany ISO 8859-1: Ä=Ae, Ö=Oe, Ü=Ue, ä=ae, ö=oe, ü=ue, ß=sz.
