Will attach the ami bios in a few, but this chipset and board implementation are not very fast, which contributes to the mediocre numbers.

We have a request from the discord discussion: try to get xp or windows 7 on it :p
Max out the ram.
With maxed ram which would be 128mb? Maybe 256mb with simm stackers? Or whatever the chipset maxed out at it might be possible?
There is a working way to get 7 setup to run on a system with 96-384mb of ram which usually won’t even run. It’s a hex edit of the iso file.
But I think you will not be able to load 7 setup because of lack of acpi support so that will be big issue. XP will likely work though.
This is a hybrid 386/486 chipset, so anything that ever ran on 486 will work.
XP will be too much trouble. NT4 may be a better fit.

eh, but no one will be impressed with NT
I mean sure, for actually using the thing prob go for a 9x/NT OS. But for SCIENCE!!!, see if XP will cram onto it! Mad computer scientists everywhere are watching with great interest!
For science and for the kids.

Thanks. Your AMI BIOS works fine. Haven't noticed any stability/performance difference compared to Mr. BIOS but it is good to have the version that is original for the motherboard.
Just for fun, what happens if you pull the one 32Kx8 TAG chip, and replace it with two 8Kx8 chips, one in the empty socket next to it? Or maybe try putting a second 32Kx8 in that empty socket?
I am wondering if that will enable write-back caching mode on that board. If it works test it with Cachechk.
I also found the TH'99 page for that board: https://stason.org/TULARC/pc/motherboards/U/U … 86WB-CACHE.html
Life isn't long enough to re-enable every hidden option in every BIOS on every board... 🙁
This is what happens with cache sockets fully populated and SLX2 CPU:
The manual says either single 32x8k or two 8x8k when using 256k. But will try to use two chips.
Write-back cache L2 is enabled (confirmed).
The fastest timing I could use is 3-2-2-2.
Surprisingly, disabling L2 cache delivers almost double memory throughput which is likely better for application performance (unless running 386 where any cache helps a lot).
Will try to see if it can be tweaked.
Try using write-through cache in BIOS.
