I have a Micronics 09-00144-02 REV A3 motherboard with PhoenixBIOS A486 (H45787 chip) ROM BIOS PLUS Version 0.10 G22-2LB. It's a really, old, dusty, crappy BIOS from 1989. Anyone had some successes flashing this thing to something more recent? Appreciate any advice.

Considering the age of this board it's unlikely you'll find a newer version of it online. Maybe someone did back in the days but they probably had to call for the technical service or something.

However we are interested by infos about your board for UH19 (see signature) and even if possible a bios dump 😀
If you find a board using the same chipset, it's likely that the bios designed for it will work on your board too 😀

None of the boards on your website were an exact match, from what I can tell. This one is the closest: http://www.win3x.org/uh19/motherboard/show/3733

An exact match is here: https://www.arvutimuuseum.ee/th99/m/M-O/32128.htm

There is ! It's over here ^^ http://www.win3x.org/uh19/motherboard/show/3749

My site is an interactive version of the other site you linked. Basically I took the static pages, parsed them and made a database out of it. It also makes updating or adding new pages very easy.

By the way, the closest BIOS image I have found was from another post on Vogons:

Gateway 2000 4DX 66V Phoenix Bios file?

This link:
http://files.mpoli.fi/hardware/ROM/OTHER/

DXLBRD.EXE 1995-11-20 00:00 60K BIOS recovery disk for Micronics DXLB motherboard (Micronics part number 09-00144 or 09-00169) BIOS version: Phoenix 0.10 GLB05

It is dated 1995.

The Micronics chipset boards almost exclusively used Phoenix BIOS as far as I can tell. I believe Microid Research made replacement BIOSes for some of them, but I don't recall if we have those in the archive or not. You can check.

I found the original BIOS firmware on Micronics.com via Wayback. Looks like this is a Micronics Gemini VLB and there's an updated BIOS, G26-2LB:

The updated BIOS can be found at:

The original G22-2LB bios can be found at (G22-2LB.exe):

Oh very nice catch ! 😮

I'm going to add them to the UH19 page. Since you have the motherboard, would you like to take a picture of it for the page ? 😀

Those BIOSes work in PCem. That is indeed an old BIOS. It looks and feels more like a 386 BIOS than a 486 one. In particular, it doesn't appear to even care what kind of CPU is installed as its startup code quickly trashes the DX register - and I guess that makes sense since it doesn't appear to try and print the type and speed anywhere. The other 486 BIOSes I've looked at have a giant table in them to handle Intel/AMD 486 CPUs, Cyrixes, Pentium Overdrives, etc.
I had a Dell 386 with a BIOS like this. And I still can't remember how to get into BIOS setup. Ctrl-Alt-Enter? or something weird like that, but it doesn't work.
This does seem like an ancient bios for a board with all 72-pin SIMMs. I wonder if Phoenix was an easier BIOS to work support for onboard IO into for these old boards. Maybe Phoenix was the cheapest since Micronics wasn't a common chipset and they needed a custom BIOS?

Was there something in particular you were hoping to get with a new BIOS? Eyeballing it, it seems the only difference is the later one might support 2.88MB floppies.

Why do you have two CPU sockets? Is one just an upgrade socket?

How about a MR-BIOS ROM file repository?

I think there are two files for micronics asic boards here.

Oh uh this image is useless for me, I need a image of the whole board without anything coming over it (cards, cable, disk bay ...)

Please do not take this wrong but think you are being a bit too picky and using the words "Oh uh this image is useless for me" is a bit extreme as any photo is better than no photo. Also I gave some very good images and info about the FIC 486-ELI6-II and the Mitac IH4077C in other threads but neither has even a hint in your new database. I respect what you are doing but think you may be being a bit too extreme in wanting things too exact to certain criteria in order to include in your database instead adding of what little someone is able to contribute. Just my opinion ...

Hate posting a reply and have to edit it because it made no sense 😁 First computer was an IBM 3270 workstation with CGA monitor. 🤣 Second computer a 286 12Mhz with real IDE drive ! After that came 386, 486, Pentium, P.Pro and everything after....

Oh no I sound like a prick ><

I'm sorry, my choice of words isn't always the greatest, I still need to improve my English skills (and I rarely re-read myself, but now that you point this I notice it).

Now it's true that I have set some criterias to have an acceptable image. The thing is, sometimes bad images at least let me document the chipset infos, but for this image, it doesn't really bring more infos than the schema we already have.

Again I should have picked my words better and I apologize for that.

As for your FIC and mitac, I think it's just that we haven't been checking them yet ^^
We have thousands of motherboards to go through and we're less than 10 to handle the task.

Sorry my choice of words was not very good, having the best quality image is important for many reasons.
