Pentium Pros are sexy, indeed.
It's funny how the cost of these things has changed. Several years ago, I needed a replacement Proliant 800 (dual PPro 440FX) motherboard so I got one on eBay for some small amount of money. The guy was moving and wanted to get rid of stuff, so he also tossed in a pair of VRMs and a pair of 200MHz 512KB CPUs for free. Today that would never happen - Pentium Pro parts have gotten expensive. I wish I had bought a more "normal" socket-8 motherboard back then.
Those 1MB chips are awesome, but kind of scary at the same time. I like that Tyan board.

Amazing!!! So jealous!!

How does such a system stand up to modern use? Ie Win XP + youtube/video playing? 😈 😈

Dual PPro?

I guess not even 240p...

144 would be sweet enough 😵

Will test out XP on mine when I finish my P4 and Athlon XP boxes. Currently have Ubuntu 12.04 or 12.10 on it and the CPU's max out but it does load and run 🤣.

Tyan had a bios update program you could download from their website. Unfortunately it didn't work however I managed to get hold of a suitable version of the award flash program which I ran from a floppy disk.

It didn't give any indication as to if the flash was successful or not but I left the computer on for quite a while to be safe then power cycled... Luckily the bios updated successfully.

This allowed support for the 1MB 200mhz chips and also added Ultra DMA hard disk support. I am a little confused about this as I didn't think this chipset supports UltraDMA?

Sorry to necrobump a thread this old, but I don't suppose you still have that BIOS file, or remember what version it was? I have an S1662 running BIOS version 4.51PG that refuses to save some BIOS settings and I haven't been able to find any other versions so far.
