OS 3.9 Install

[shadower]

Hiya,
 
I'm curious if any of you are installing OS 3.9 on top of an older OS install? I'm considering installing 3.9 on top of a 3.1 install and I'm wondering if this is possible, if so are there any special considerations. My goal is to get 3.9 installed so I can use a 80gb ide drive via Elbox fastata 4000. I haven't decided if I want to retain the scsi system drive and boot from it and use the ide drive for storage or if I want to rid all the scsi drives and use IDE only.
The system is a 3000T with Warp Engine 4040.
 Thoughts? suggestions?
 
Thanks!

You don't need OS 3.9 for this. The FastATA software in combination with a new file system like SFS is sufficient. OS 3.9 only makes it more complicated.

I was under the impression that you needed OS 3.9 for it to recogonize HD partitions >=4GB.
