ACER 286A REV 2.1 ( chipset Acer M1207-16) ( single bios chip )

For 286A check this thread and ask OP if he can help:
Re: ACER (?) - 286PLUS-16

Closest I have is a bios from a n M1209 motherboard. Deksor put the bios here:

But It looks like they have a 1207 bios's here:

I couldn't find online 🙁 maybe you have one in yours collection.

Thanks a lot

Found nothing yet
Curious if you are trying to update the BIOS or just find ones because your boards are missing or corrupt ?

missing bios chips ; (

Can you post pics of your boards please ?

I'd like to add them to UH19

Moreover this'd help us to figure out which chipset they use and find boards using the same chipset with a BIOS available 😀

sure, here they are

HYUNDAY Super 386S

He posted the bios !

I uploaded arteq's photo as well as dataino.it's bios here http://www.win3x.org/uh19/motherboard/show/5155

@arteq Notice that your board is also missing a dallas RTC chip

For the C386 I don't know if there's much to do right now. People have boards with that chipset but we don't have any bios in UH19 and it's unlikely that there's a bios for this chipset floating around online at the moment (correct me if I'm wrong !) Also the chipset seems to be "made" by the manufacturer of that board ... but to me it sounds likely that it's another unknown chipset under the hood !

For the Hyunday Super 386S the chipset used seems to be made of glue logic for the most part. It's possible that a very generic bios can work !

Deksor, do the different acer board revisions have a seperate listing?

No they don't.
