In the end I tried both of the Mr-bios files to test them, V097B5NA.BIN and V097B5NA.BIO. They have different sha-1 hash values and after flashing each one and testing I can't make out any differences. All bios options and version # appear identical.
A big problem now though, all PCI cards I have (S3 TRIO, Promise TX2 IDE controller, YMF 724) don't work. The Intel Advanced Morrison motherboard (430fx chipset) uses a LPX form factor and a riser card for ISA/PCI. All my ISA cards still work but if I insert any PCI card in the riser the computer will freeze when loading DOS. It completes POST but when loading DOS the screen stays black or is black with a blinking underscore in the top left corner. There is a PCI menu section in Mr-bios where you can assign SLOT# (1-20), INT A,B,C,D and low or high level IRQ trigger. I have tried most combinations without success. The riser that came with this motherboard has 2 PCI slots and 3 ISA.
Has anyone in here flashed an Intel-Morrison motherboard to Mr-bios and got it working with PCI cards.

There were different Morrison boards. What Intel Bios did your Morisson originally have? Were you flashing an IBM Aptiva?

Re: Zeos motherboard project

Any suggestions? Looking for an alternative bios.

I don't think MR-BIOS ever released a BIOS for a 430NX motherboard.

Was there a Pentium Mr Bios ?
Never heard about it.

Dozens. They did BIOSes for a lot of Triton motherboards. I'm running one on my 430FX based Intel Advanced/EV board.

There are over 250 of those, I identified most of them here.

However, the earliest Intel one are for 430FX. 430LX/430NX have not been found or even mentioned anywhere. Same goes for Unicore Award.

The only 3rd party BIOS upgrades for 430LX/430NX I'm aware of are from Micro Firmware, but I haven't been able to find the actual ROM files. Seem to be just modified Phoenix BIOS with support for bigger harddrives though.

So I’m stumped on this 430nx zeos board then. Unfortunately the bios it has makes it nearly unusable for what I had planned. As it doesn’t support anything non intel. And I am probably capped at 200-233mhz 🙁 (tillamook didn’t work also)

Does anyone have ANY ideas at all? Maybe a bios that will work and I can swap my io chip?

For tillamook often hardware mods are needed.

I know, and they were done 😀

Interposer that I made for the CPU has them built-in but also the cpu that I used also has them soldered. I didn’t use the mods on the interposer.

I also posted this in General Old Hardware but someone suggested it goes here:

Maybe I'm missing something, but I'd advise anyone looking for a MR BIOS image to also grab the "target5" download referenced in the "MRBIOS Big Bundle" Google Doc on vogonsdrivers.com (https://archive.org/details/target5). It is a large download that contains lots of old programs, but it contains several megabytes of MR BIOS files.

Perhaps most importantly, it contains text documents for each chipset that I found extremely useful in determining which image to use. I recently asked about something pertaining to MR BIOS images and another member provided one of these to me. I wondered where he got it. Well this is apparently the source.

And, although it ended up being the incorrect image for my motherboard, there's an image in the "MRBIOS Big Bundle" that is missing every other byte. Specifically, it's in V002B406, but the "target5" download contains the complete copy. There could be more examples of this.

Just something to consider.

Hey, thanks for pointing this out — the bundle on Vogonsdrivers is a snapshot of the catalog that I did. Seems like I've made a mistake with .odd/.even BIOS images. Normally these are presented in Target5 as both a full 64KB ROM and a set of ODD/EVEN 32KB for dual EPROM boards. Seems like in some instances while renaming the files I accidentally replaced the full 64KB ROM with either the ODD or EVEN file.

Fixed it in the actual catalog and the Dropbox archive. I think there was also a singnificant mistake in the Intel section. Fixed that as well a while ago, so Vogonsdrivers might want to reupload using the current version and maybe link to the Google Docs catalog. I've also identified and added a bunch more images since that version.

and

https://www.dropbox.com/sh/3etr4acyxtsm603/AA … CCNnj-jKSa?dl=0

I notice via Google Docs that people actually use the catalog, so I would appreciate if people use comments (or just hit me up on Vogons/Discord) to report any issues/errors or actually successfully use the ROMs with their boards. I've added the "should work with" column, and I'm gradually updating the status based on what I tested myself and found online.

Zeos motherboard project

You I believe posted a helpful reply on discord that I don’t recall where it was now. Any chance you could post here also? I think I was asking about different brands of bioses that may work.

Unfortunately this motherboard is pretty useless as a project to me if I can’t figure out how to get non intel chips in it. I want to put m2 and k6-3+ in it

Hey, glad I could help, but I don't remember where that conversation took place. Feel free to repost those messages — I feel like you should be able to document your project anyhow 😉

UPD: I think this was actually also in regards to an issue with 3rd party BIOS images for early Soc5 boards.

I added some Mr Bios manuals to vogonsdrivers.

http://www.vogonsdrivers.com/index.php?catid=77

and I updated the bios bundle here: https://www.vogonsdrivers.com/getfile.php?fileid=1971

Is there an editor for Mr-Bios rom files, like awdbedit or AMIBCP.

There were different Morrison boards. What Intel Bios did your Morisson originally have? Were you flashing an IBM Aptiva?

Your right, there were around 6-7 oem variants of the Morrison. My motherboard is from an IBM PC 330/350.
https://theretroweb.com/motherboards/s/intel- … d-mn-morrison64

It appears identical to the IBM Aptiva (2144-S15) Mr-Bios image I used (V097B5NA). Using that bios the board works fine with the onboard trio64 etc and ISA slots on the riser card. Any PCI card hangs after post before loading DOS.
PCI cards work using the original ibm bios - the identical bios file is used for the IBM Aptiva (2144-S15) - LPJT63A.

Does anyone have the MrBIOS image for the SIS85c471 chipset?
