Also check, if you have correct BIOS for your board. I had a similar problem with 386 board (two banks, 8 RAM slots, only 4 worked) and problem was only in wrong BIOS. Board normally worked with this wrong BIOS, but only 4 RAM slots were functional. Some previous owner used wrong BIOS. My thread …

I again tested this card in two different motherboards and it works normally after every reset. Weird, it's somewhat picky. Maybe some settings in BIOS... Now is in my main 486 gaming computer and let's see...

Important update: it was wrong BIOS! I purchased Xgecu TL866II Plus programmer, tried some other BIOS and after three attempts finally find correct one! It's directly from DTK,(not Award or AMI), not much settings for chipset, but it works. https://hwmuseum.pp.ua/motherboard/2053.html

Good tip! When i got this board, BIOS chip don't have it's original sticker, but this silver piece of tape over window. Probably someone manipulate with BIOS. Must find original BIOS and compare with my current.

Correct me if I'm wrong: One CAS and RAS signal for each bank Here are 2 banks, each four 8bit slots = 32bit for 386DX = 2x CAS and 2x RAS signal from chipset to memory

Cache is detected and populated correctly for 128 kB by "PEM-0036Y Settings Sheet" from ultimateretro.net. Also silkscreen on board correspond to this. I measured resistance by your instructions and it's very high (5,6 MOhm) in all I/O in all three buffer chips.

Used 8 identical 1 MB modules with three chips on it, tried randomly changing their position in slots and nothing - still detected only 4 …

Probably no, HDD detection and configuration is still through motherboard BIOS. But Promise chip must have it's own "BIOS" stored somewhere, but on card is only one ROM for VGA. Maybe in Promise chip itself, datasheet would be very helpful, but it's unobtainable (or I didn't find it).

Have you tried reset internal memory in Dallas chip? Maybe it's content is somehow messed up and prevent notebook from starting. I think this notebook don't have jumper for CMOS memory reset, so you must force reset manually. It's on pin 21, but only models with "A" letter (for example DS12887A) on …
