Could the M396F chipset be made by Acer? M1217 for example? Good try, but I doubt it. Ali-m1217.png m396f-sarc.png The dots are different, and also the traces seem to connect differently ! Chipset makers generally buy the chip package from other companies and just add the silicon, so it is entirely …

Nice :) Thank you I've made some progress with other PCChips boards such as the M321 or the M396F They both have chipsets with "quad dots" pattern. Four dots in each corner with the one in the corner of pin 1 being deeper than the rest. I've spotted this pattern on via chipsets, opti chipsets and …

Yes 😀 Also the BIOS string is ESIS-1393-040990-K0 and the chipset is SiS 'rabbit'

Well while dumping your 286 could be useful to someone owning the same board as you, unless your board is identical to his, it's not going to help a lot to identify it ^^

Maybe there are more infos in the bios ? Do you have anything that could be used to dump it ? (even a pentium era motherboard could do the trick with uniflash !)

Well ... Actually I compared the SARC RC4018A4 to the UMC UM82C491F because that was the first chipset that looked similar that I had in mind ... But what if it's really the same chipset ? I now have good reasons to believe it's the same chipset. RC4018A4.jpg UM82C491F.jpg Each chipset brand has its …

It is well known that PCChips is a shady company and that they've faked many things in their history. For example, in the pentium era they rebranded chipsets with many strange aliases that are documented here : https://www.hardwaresecrets.com/chipset-aliases-tx-pro-vx-pro-and-co/ For the 486 era …

Well it's not that surprising considering you have a 486DLC-40 ^^ (the chipset is probably a good one as well)

Just take a voltmeter and check if there's voltage on the pins 😀 If there's a voltage, the traces are connected because it wouldn't make any senses to have the power rails connected and nothing else ^^

Well I was wrong when I wrote that (an early version of the m919 has cache slots) however the one in your picture is the later model which has NO cache whatsoever, and the "empty slots" are indeed having the traces getting nowhere.

Try eBay. Beware of fake chips though. 1MB is going to be costly and won't bring you much though, 256KB is plenty enough.
