As you say, also SCO OpenServer will run on that dual pentium-1 board just fine. It's System V Release 3.2 based, has TCP/IP, SMP support, an optional X11R5 GUI, and all the unix bundle (with the original true blood Bourne Shell, also).

From what I remember, there was also a SMP version of NT that was designed for dual processor systems. I'll have to see how the dual processor thing works. I have a bunch of IBM PP200s that were all dual processor capable. :D

The thread was opened by asking what else *besides* Windows NT supported multiple CPUs. NT Workstation supports a single or two CPUs. The next level, NT Server, supports between one to four CPUs. Above four CPUs, I remember "NT Enterprise", but forget the upper limit of CPUs you could use.
As I remember, you had to select the multi-processor kernel on install...
There are several IBM Servers (and a desktop system) that were dual PPro-capable. A few of those had a dual Slot 1 CPU card that could be used instead. In truly huge cases (but ultimately the same motherboard) there were a couple quad PPro servers.
And mixed PCI/MCA bus Server 720, that could have up to six Socket 7 Pentiums, or five CPU cards to install a second memory card to reach up to 2Gb RAM...
Windows 98SE can support dual processors, but it's by way of a special new API that the community has created, and new programs must be coded to work with it. It would be a cool project to do it on era hardware like a dual Pentium box, though. :D

I would love to see info on that. That strikes me as both insane that any community effort would bother, and incredible that they got it to work.
Back in pre-OS-X Apple days, the OS itself wasn't multi-processor aware, but a system extension made the second CPU available to applications. Is it something like that?
Very lively Win9x community here:

This guy (a member at the MSFN forum aforementioned) has made many 98SE breakthroughs, including the API for multicore, also one for 64-bit RAM access, a patch to fix the RAM limitations at ~1.5GB, etc. Some of these things are sold, not given away, though - in fact all of rloew's things are.. which is why they haven't caught on...
