Hi,
There should be no problem getting Warp 3 to work on that computer, or to recognize your second hard disk or CD Rom, it likely just needs some updated drivers.
The base Warp 3 is ancient by today's standards, even when it came out it didn't take long for IBM to update the drivers to fix some of the very issues you've run into.
My advice is to replace the IBM1s506.add driver with danis506.add
You'll likely also need updated drivers in IBM's IDE fix, or...
It is probably just easiest to install Fixpak 40. This will update Warp 3 to the latest code level that IBM had available for Warp 3, plus install a bunch of the updated drivers too.
Since installing Warp 3 red / blue / Warp 3 Connect (red / blue), etc - has been covered before I'll just direct you to the previous posts. Be sure to check:

You just need to install MPTS (which can also be downloaded from IBM). If you want to talk to other computers on the network via netbios file sharing, you'll need something more, either Warp Connect (which contains the Peer networking stuff), or you can also use the command line apps that are a part of Samba.
For the video upgrade, you'll likely need to have Fixpak 40 installed. Once you do that, you can then run Scitech SNAP which will work with a lot of the newer video cards.
As for ODIN, that's more of a hit or miss. Some people have managed to get it to somewhat work on Warp 3, but generally it doesn't work for most on Warp 3. Your best bet is either Warp 4 or (preferably) eCS.
