C: partition 2Gb D: - E: - F: partitions set to 2.33Gb = 10Gb one hard disk.
OS 2 Warp 4, no fixpacks off the first series CD, proof that it works is the 
fact I am writing this on the machine and this message is posted from the 
Rockbbs.

The reason I use it this way is simply because it works, it sits here for 
months doing it's thing and I only empty the trash every so often.

The real fun was setting it up on an old 486 that wouldn't see the hard disk, 
that was on an HP Vectra 66, you tell me how I made that work ;)

 HR> newer as 4.5: up to 1 GB.
