G’day all,

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.
I’ll grab a photo of it tomorrow.
It uses two EPROM chips (27C512 from memory) in an odd/even config.
I was successful finding it online however, no bios dumps are available.

If anyone knows about this Taiwan made board with chips CS8221 chipset, or better yet, has a bios dump that might be compatible, let me know!
Thank you

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.

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

Big photo

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...

Hate posting a reply and then have to edit it because it made no sense 😁 First computer was an IBM 3270 workstation with CGA monitor. Stuff: https://archive.org/details/@horun
