Among them were many versions of MR-BIOS for the C&T PEAK/DM chipset. I have a 386 board based on this chipset. It's a Silicon Star/Abit FU340. I tried every single PEAK/DM MR-BIOS, and not a single one could detect the external cache. I really don't understand, because FU340 is a very common board with this chipset, so you'd think it would easily work. Is there anyone else on here with a 386 board with PEAK/DM that can try it out?
My board uses the B1 stepping chipset. I was testing with a 386DX-40, 8MB DRAM and 256kb cache.
I have the same motherboard with the same problem.
Also, there are at least two more reports out there about similar mobos and chipset.
All these early, wide format, 386 mobos are slow and clunky.
I think you mean long, not wide. I actually disagree about all of them being slow and clunky. Some of the fastest ones are actually full length baby AT. AMI Mark V Baby Screamer being one. There's also a Chaintech board with SiS Rabbit chipset that's quite speedy. The FU340 is not exactly a slouch either. It benchmarks in DOOM pretty well, and it has impressive memory throughput.
Did you start any threads about your experience with the board?
I have managed to test one of the MR-BIOSes that were available. My motherboard has 64kB cache installed and it showed fine on BIOS screen (used V051B321 file). I'm attaching memory results from Speedsys too.
I have dumped my original AMI BIOS that came with my motherboad and it's called FU3-V8 PAGE MODE BIOS. I've compared it to other BIOS files that are available on the internet and it seems different. I'm attaching it too, maybe you'll find it useful.
Well since I worked with TH99/Microhouse Technical Library for over a year now, I noticed that many mistakes were made, and also I recently figured out something new when I wanted to add a 486 mobo I had.
This is the 486 mobo I had, a Gemlight GMB-486SG rev 2.2.

Now THAT looks close to what's in MTL/TH99 ! But it's the manual's revision, not the motherboard's !
But since they probably used manuals to create Microhouse Technical Library (I doubt they went and retro-engineered nearly 6000 motherboards), they probably made other mistakes of that kind.
TL;DR this "FU3 rev1" thing is probably a non issue and just a manual revision, not a motherboard revision.
Please post a high resolution picture of your FU3 motherboard.
I should really try setting my external cache as 64kb to see if the BIOS will pick it up. I remember Feipoa had issues getting 256kb cache to work on his FU340 with AMI BIOS.

That was used in most of the machines of a client I was working at back then. I think I have all the manual revisions. I may even have noted what manual goes with what board revision.
Im working on a Chips PEAK/DMmotherboard right now that looks like yours.
I cant get it to boot. I have tried flashing it with AMI bios but then it wont even turn on.
Anyway i have saved my BIOS if you would like to try it out.
Here is a picture of the board and the attached bios:

Hi! Is it possible for you to share the MR BIOS V051B321 file? I cant find it anywhere.
256kb works fine on my board with AMIBIOS and C&T BIOS. But, it is not detected with MR-BIOS. I can't remember if I tried 64kb setting with MR, but I am pretty sure I did.
