So I did a thing where I've cross referenced most of the known MR BIOS files with official documentation and made a list of everything. There are around 500 files, but many of those are different versions of the same BIOS (especially when it comes to Intel/Asus motherboards).

I'd like to copy the roms and put the document here if that's OK: http://vogonsdrivers.com/index.php?catid=77&menustate=32,29

Any idea what the differences between these ROMS are?

Can't help you with T-/T+ thing, it was not explained in the docs, unfortunately.

I think you should add my Google Docs table as a download and not a link.

GigAHerZ put a link to a pretty good link that offers an explanation of the different version. (T) Turbo Switch, (TL) Turbo Light (CL) Cache Light

I put the file names in the file description. That's about the best I was able to do tonight.

Woah. There are motherboards with headers for cache lights? Where can I get one of those?

Did a bit of an update. Added around 40 new BIOS files. Most are just different versions for Triton-based motherboards (versions 3.19-3.31).

What's more important is I've rearranged the whole structure of the archive. Now almost all folders are called by MR BIOS part names (e.g. V097B50D) and are sorted by versions (different versions of the same BIOS share the same part name, as they do in MR BIOS docs). This allows to crossreference partnames with different motherboards they support — I've already identified a couple of images that way.

Naturally, I'm not sure how to match most user dumps with part names yet and I don't know the version number for some of them (they are now in the "TBD" sheet in my Google Docs).

Here's the list, everybody can comment on the table.

Here are all the files.

Nice stuff. Splitting it up by CPU makes things easier to find.

I've gone through this thread and the mr-bios user manual (133 pages) for v3.30, can't find what the maximum Hard drive limits supported are. Does mr-bios support drives > 128GB in the latest version (I believe version 3.46 the latest?).

MrBios 3.30 came out in in the 1996-1997 time frame,
MrBios 3.46 came out in in the 1998-1999 time frame,
Seems very unlikely it supported the 2001 standard.

528 MB limit - BIOS before July 1994 rarely support drives over 528MB. They were limited to Cylinders <= 1024, Heads <= 16, Sectors/Track <= 63
2015 MB limit - BIOS before May 1996 rarely support drives larger than 2015 MB. They were limited to Cylinders <= 4095, Heads <= 16, Sectors/Track <= 63
4.2 GB limit - Some BIOS before February 1997 have the first ECHS (Extended CHS) limit. DOS and Windows 95/98 cannot handle 256 heads. 'Large' mode in the BIOS produces an alternate geometry by doubling the number of heads and halving the number of cylinders shown to DOS until cylinders <= 1024. The limit for this method is 4032 MB (C=1024, H = 128, S = 63) for drives that report 16 heads.
7.9 GB limit - Some BIOS before February 1997 had a Revised ECHS limit. 'Large' mode in the BIOS presents an alternate geometry using multiples of 15 heads, up to 240 heads. This method stops working at 7560 MB (C=1024, H=240, S=63)
8.4 GB limit - Some BIOS before February 1997 has the final ECHS limit - Bios geometry selects head head value from the sequence 16, 32, 64, 128, 255 to present an alternate geometry up to (C=1024, H=255, S=63). Hard drives larger than 8.4GB report a geometry of C=16383,H=16,S=63 to indicate that they are larger than can be described using ECHS geometry translation)
33.8 GB limit - Many BIOS before August 1999 stored the cylinders as a 16 bit value, so they could not process cylinders > 65535.
137.4 GB limit - BIOS before September 2001 only used ATA-5, which used 28 bits to identify each LBA sector, limiting drive capacity to 137GB. ATA-6 added an additional 48bit LBA sector field. Hard drives over 137.4 GB should report an LBA capacity of 0xfffffff sectors and report the actual value in the 48-bit field.

Were there any MR-BIOS releases for motherboards newer than Socket 7? Or did it just end with Intel Triton boards? Did they support any other chipsets for the Pentium? I can see ony OPTi chipset, but nothing else.

They were taken over by eSupport/UniCore somewhere between sept 25, 2001 and november 30, 2001

Unicore was the patching/upgrade service from Award/Phoenix. So they swiftly killed off their only competitor after that.

Just a quick report - the MR BIOS image for the Octek Jaguar V seems to work on my C386MX board with an MX305/306 chipset. And it works vastly better than the AMI BIOS it replaced.
Using the stock 386DX-40 CPU, no FPU. Don't have a 486DLC to test.

Life isn't long enough to re-enable every hidden option in every BIOS on every board... 🙁

Nice! It's a cool board. I have it with the stock bios, need to get some eeproms to upgrade it.

Looking for Mr.Bios to suit my Micronics 80386 ASIC cache (09-00050-xx)

Tried one of the micronics ones that seemed
Like the best fit but no post.. I did place the mr.bios on the hi rom?
