Re: 1.9MB floppies
the OS/2 Warp addon that gave internet support?
I think you misremember. IIRC (and Wikipedia appears to confirm this, for what that's worth), OS/2 Warp included TCP/IP. Warp Connect added LAN Manager / NetBIOS / SMB / DLC / etc. support. Warp 4 had all of that built in, plus Java and speech recognition.
