How about a MR-BIOS ROM file repository?

Hi there.

Extremely tired of AMI 386 BIOSes and their HDD size limitations i decided to try a MR-BIOS that would work with my 386 motherboard. While looking around i noticed that finding MR-BIOS images was not that easy. Luckily my 386 motherboard uses UMC 481/482 chipset and there's a MR-BIOS around for it. I use it now and can't think of going back to AMI BIOS again, system speed increased slightly, i can now use a 1GB CF card without any issues and without having to use any drive overlays. The BIOS is very configurable and i really like the keyboard shortcuts for Turbo and cache disable.

Unfortunately for other users, with different boards and different chipsets, finding a suitable MR-BIOS might not be that easy, in fact it might be impossible.
There seems to be a couple of other versions around, for ALI and OPTI 386 chipsets, but i would like to call out everyone to work together for a repository where we can gather all these MR-BIOS versions to be available whenever anyone wants to use them.

I want to encourage users with boards with MR-BIOS upgrade ROMS to dump their contents and make them available. All we need to do is to find a place to host them, maybe VogonsDrivers.

Sounds like a great idea.
Some users might be discouraged to physically unplug the BIOS ROM but, there is no need for that.
You can use Navrátil System Information (NSSI 0.60) to dump your motherboard BIOS contents and save it to a file.

^ oh that's great, the software is free and found here: http://www.navsoft.cz/products.htm , just go to Tools -> Save BIOS

I'd sure like to find the MR BIOS VLSI Topcat, SiS Rabbit, and C&T Peak-DM. Some time ago, I posted something here: https://www.wimsbios.com/forum/other-bios-upd … set-t14343.html

In the above link it was mentioned that esupport.com bought MR BIOS. My efforts to obtain anything from esupport.com failed miserably. Has anyone else been able to contact them? What was your experience?

I think completing the list of the MR BIOSes is about as likely as finding all of the classic Doctor Who episodes.

Realistically we have a high probability of finding OPTi 499 and 291/95, because I've seen them frequently fitted on the Alaris SLC/DLC boards. Also, I think we can get the Headland HT340, because it was previously dumped for the mobokive from the Octek Jaguar IV. There's also a guy on youtube who did a video of a 386SX system that had I think either an Intel or VLSI chipset and MR-BIOS, as well as somebody on this forum who has a MR BIOS for one of the ETEQ chipsets.

I have sent a message to that YT guy but it is my understanding he has sold the mobo.
So noone else has any other chipset BIOS? All we have are the ones on the list?

I would like to find MR-BIOS for the Forex chipsets, specially the 421 and for the Headland HT12.

Feipoa i do remember reading something about the discussion you had with a supposed BIOS expert. Was it you or am i mistaken?

I'll check my boards for Mr. BIOS. Although only 3-4 might have it. Over the weekend I played a little with Alaris Cougar II 486BL that seems to have Opti 82C499.

Definitely a comfort-list I'd love to have. Every single FTP site I've backed up I've looked to see if there was some golden-gem rare Mr BIOS directory, but none yet.

Closest things I've come to were these, and I bet you all probably have all of them on these FTP sites:

these FTPs have some BIOSes for newer socket7/8 systems - we need the good-old stuff 😀

I wonder if there's a MR-BIOS for an Intel i430TX (Anchorage) motherboard? I have an Abit AB-TX5 motherboard that has the Award BIOS (crappy in my opinion due to HDD limitations), and I need to look and see if my Packard Bell Pack-Mate 28 Plus (PB450M) supports it by comparing the chipset that is listed on here.

have a look here, maybe there is something you can use: http://www.mediafire.com/file/srn25jyr571b255 … MRBIOS_FTPs.zip

I am going to build a system with this board sometime in the near future, I will try to dump the bios with uniflash..

For now, please see attached the copies I found of the latest and large HDD patched Mr BIOS bioses.

Exactly. Every FTP site I found, nothing except either these or a text file about a BIOS for a 386/486 board, but no actual BIOS files. Looks like the repository will definitely have to come from the community pulling their BIOS files. I don't have any, that I know of, on my boards.

Maybe someone can contact whoever is responsible for mobokive to see what happened to the Jaguar IV and V files. One is the MX chipset, and the other is for HT.

I dumped a MR BIOS rom a few months ago here: Forgot how much old hardware I had I don't think it got put anywhere else yet.
Last week I got a VGA card from ebay and confirmed the board POSTs.

Nice, I didn't see that. Now we finally have a MR BIOS for the original 386 Forex boards, which are quite common.

There is a section on VogonsDrivers for BIOS images, if someone wants to mirror them there, go nuts!

(Well don't "go nuts", upload the files and give them meaningful names and descriptions! 😜)

Nice! Would love to get images for both Forex 421 and Headland HT12. Headland HT12 286 boards are quite common but i have never seen one with a MR-BIOS upgrade.
