correction for Gigabyte GA-586ATX:
https://www.ultimateretro.net/de/motherboards/2734#downloads

Wrong picture by "jaZz_KCS". This is from GA-586ATX3. Watch the memory slots orientation.
Should be removed/moved to GA-586ATX3.

QDI V4S471/G

Maybe you wish to add this custom bios i've uploaded there for this board. (second bios file uploaded in thread, first one still had one bit not flipped, which was necessary) I searched for the very latest bios for that chipset in ultimateretro page and then did some modifications to it.
So when adding that bios, it makes sense to comment on it very clearly, that it is not official. But at the same time that it does enable as many settings as possible in bios, and it fixes the L2 cache write-back on the board.

And on the CPU section, i can confirm this board to work with 5x86-75, which is 4x33MHz cpu with write-back internal cache. So probably all cpu's "in-between" are good to go.

"640K ought to be enough for anybody." - And i intend to get every last bit out of it even after loading every damn driver!

There's and unknown 286 board with BIOS: https://www.ultimateretro.net/en/motherboards/6749
Which I think is the same as the Chaintech ELT-286B-120GM: https://www.ultimateretro.net/en/motherboards/5176

Differences that I can see are that the Chaintech has:
-some silkscreen removed from unfitted capacitors, particularly around the ISA slots.
-an i286 12MHz, compared to an AMD 286 12MHz on the unknown board
-Has Headland HT101&2 rather than GC101&2 (think these are the same?, something about Headland buying G2 according to DOSDays)

Based on what I think are a few date codes, it looks like the Unknown board was made early 1990 and the Chaintech late 1990 (which would fit with the newer board having unneeded silkscreen removed). Chaintech may have a replacement KBC (copyright date goes to '92). The unknown board looks closer to original, and has Phoenix stickers on the BIOS and KBC, so it's likely that the Phoenix BIOS listed on that one is the original from the board.

Maybe copy the photo and BIOS from 6749 to 5176 and point 6749 at 5176?

board : CDTek Super 286 (ACT CHIP) https://www.ultimateretro.net/en/motherboards/6744
lists chipset as 'ACT A27c011', while the board does not have that chip on board.
Only an A27C001 is present,
unlike the two other boards listed on the search which do have the 'ACT A27C011' on board.

I recently came into possession of this board and almost missed it on UR due to this discrepancy.

I'd like to report a bad BIOS for PCPartner VIB804DSE (35-8804) https://www.ultimateretro.net/en/motherboards/6632#
There are different variants depending on what Super I/O chip is on the mobo, mine has the ITE so that's the BIOS I've tried. I had to program it directly into the chip via programmer since the original BIOS got somehow erased, and this one wouldn't work - it dies with code 41 and beeps that suggest memory issues or BIOS corruption.

Then I found this page http://bios.rom.by/PCPartner/old.htm but unfortunately the files are gone. But the vib804dse.zip filename is rather unique, so I searched for it and found it here: https://www.elhvb.com/mobokive/archive/Clayto … bios/index.html
This ZIP not only contains the BIOSes for all I/O chips, but also the flashing program and a brief README file. Again I've programmed the image directly to my chip (and it is a different file) and this one booted without any issues. Perhaps it would be possible to ZIP the existing file but add (bad) or (suspect) or something of the sort to the name, in case other files do work and it's a newer version, and then mirror the working file I found.

BTW the photo used for VIB804DSE is actually that of VIB804DS mobo. Not sure what the difference is other than E variant having a newer 586B chipset (instead of 586A). I had to peel of PC Partner sticker to find which one I have.

Another correction is to the Unknown (SiS471 3VLB) https://www.ultimateretro.net/en/motherboards/10291
First of all, this mobo requires 36-bit SIMMs (the 72 pin ones). This is rather important, it will not work at all with the more common 32-bit (no parity) ones. Also seems very picky about 8MiB SIMMs, it's better to use 4, 16 or 32 ones.
Listed CPU clocks are also incorrect, unless there are more clock chip variants - it should be 20, 25, 33, 40. It is possible to set 50MHz as well but it's not listed on the mobo silkscreen, seems to work though. VLB does not like clocks above 33MHz no matter the jumper settings but it could be down to my CL cards. At 33 it's perfectly stable. Also has cold boot issues with SX CPUs, this goes away once the mobo warms up. It's something NMI related and doesn't affect DX CPUs as these are jumpered differently. Again, this could be a problem with my particular mobo but I would list that in the known issues maybe?

I have something for Digital DECpc LP:

Here is BIOS image and pictures from front and back.

Those are from DECpc 466D2LP, model PC746-BB.

These are not yet added to the DECpc LP page but it seems someone has uploaded some pictures with later BIOS than I have. To whoever uploaded those pictures, could you upload the v1.22 BIOS image as well (I have 1.20)?

Soyo SY-030E2
https://www.ultimateretro.net/nl/motherboards/4650

I see pictures of both the 030E2 and 030F2 boards on this page. As with many Soyo boards, the changed letter is just a different revision of the same board and they usually use the same BIOS.
So this page could be made into a combined SY-030E2/030F2 page.
Looking at the pictures, the only difference I see is a 3.3V voltage regulator on the 030F2, but not on the 030E2.

I had an SY-030F2 board back in the day and it came with a REV. B1 BIOS. Later I found a REV. C2 BIOS that worked fine as well. Here are these Award v4.50G BIOSes:

The Siemens Nixdorf D1141 is missing a description of the front panel connector. I couldn't find the information on the web but a moderator of the Fujitsu support forum (German) suggested that it's identical to the one of the Siemens Nixdorf D1107. This one has the description in the 'Additional Technical Manual'
(I have the D1141 but haven't tried it, yet)

There are differences in components around the CPU area that I can see for a start. It's possibly a different revision of the board or a slightly different model. I have named it Chaintech ELT-286?-120?? because that is about as close as I can get. Maybe at some point the actual name will show up.

Missing board: PCChips M925ALU. The main difference with the other M925 models is it has the higher 533MHz FSB (P4M266/A northbridge -- the "A"), onboard 10/100 LAN (the "L"), and the onboard USB ports (the "U").

The manual for this model also mentions all of the other M925 models and their differences which is pretty helpful, presumably because this was (one of or) the latest of the M925 models.

Again, read from EPROM from my motherboard, older version of ones that are already in download section but since we're collecting 😀. I Tested both version from download section and they worked fine on my motherboard.

Read from EPROM from my ECS UM4980 v1.1
In downloads section in Ultimate Retro there's Award BIOS and blank spot for Phoenix one. I guess this is the one missing.
Just for kicks I tried flashing Award version and testing it on same motherboard and it works. Didn't knew that some motherboards could come with either Award and Phoenix BIOS'
