SFU replaced the posix subsystem with an OpenBSD port and more capable thing for NT/2000 etc.

SFU was so much later to the game, while BOW ran on Windows 3.1 which would have been great had it had far bigger appeal as you could just run it on such lesser machines. The best part being no formatting, no device drivers, or changes to the OS at all. I just copied over to my PS/2, and was playing hack 1.03 in no time.
