I got it to install successfully, in VMware Server 1.0.2.

The solution is to boot normally with the "id.dd" floppy image provided
by Corey Lindsly, with the ISO image also provided by Corey configured
as IDE 0:1 (first channel, slave), and with a virtual IDE disk (I'm
using 8 GB of size) as 0:0 (first channel, master).

This setup leads to the already known IDE driver hanging. It's a
problem with the IDE driver provided by SCO with UnixWare 2.1. So,
when the install process asks whether you want to use a "HBA diskette",
load into your PC emulator's virtual floppy drive the updated "HBA
diskette" image provided by SCO for UnixWare 2.1.3, which is here:

This will stop the UnixWare 2.1 IDE driver from hanging, and the
install process will proceed successfully to completion.

It should work equally well in VirtualBox.
