2* 27C512 is pretty big BIOS (plus a full set of DIAG tools in E000 segment), most of these mobos use 2* 27C128.
Looks to be pretty standard 286 mobo with CHIPS ICs, I have just posted a BIOS for a similar mobo: Re: 286 "CHIPS" mainboard with missing parts...

I would be interested in the Russian BIOS you have, please dump it if you have the means to do so. If it does use '512 EPROMs it might contain some useful additions that could be transplanted to other BIOSes.

I’ll have a closer look tomorrow and add some photos of the board and ROMs. They’re either 256 or 512kBit each. As for reading them I do have a untested vintage ISA card based programmer I’ll have a play around with but I’m hoping to get a T48

Here are the photos in question.
Indeed they’re both a 27C256 not 512.

A couple of years ago now I picked up this board off of eBay. With it came bios chips that are in Russian and thus, not really useful to me.

Hello!
Bios in the application.
I'm very, very interested in Russian bios 😀

If you don't have a programmer, you can try reading the BIOS in NSSI or ASTRA7
BIOS shadow (if present) - disable.

Hi, I don't have the board but I agree with the others to save that Russian BIOS.

Because, knowing how it handles codepages and characters alone would be interesting.

Maybe it was originally being used with a CGA or Hercules card with a Cyrillic font ROM?

Who knows. Definitely being worth to be preserved. 😃

Tools like NSSI or one of these tools can easily help to dump the BIOS.

Could you dump the KOMPAN bios?

Unfortunately he has not been back since 2023-08-29 according to his profile...

G'day, I don't have the motherboard on hand,but when I next do I can certainly dump it for you

That is absolutely terrific! thank you for supplying that. As I've already mentioned, I'll be sure to share the russian bios

Here is the Russian KOMPAN BIOS dump. Sorry for taking so long to get it. Hopefully some interesting information can be derived from it.

Would it be possible to also have the video BIOS?

That's really cool. I have tried to run the KOMPAN BIOS in the emulator and patched the VGA ROM to contain a cyrillic CP866 font.
Never seen a Russian BIOS before.

This is very interesting. I've never seen the motherboard work before, so this is new to me also.
I've never emulated a bios before, so I'm curious as to how you did it.

I used 86Box to emulate an AMI 286 PC with a NEAT chipset and a Trident TVGA8900D VGA card - just replaced the rom files of the emulator, so the emulation isn't perfect but close enough to see the initial memory test.
