Oh cool! Can you try my program anyway? 😉 I think then it should also be possible to call the Setup with a hotkey. Maybe I will take a look again if the mentioned adress is called somewhere within the BIOS.

Some photos of the manuals. Are you looking for something special? I cannot make a photo of every page. Maybe I can remove the binding and put it in my slide scanner...

Hi, yes, not much time at the moment... For the ISA card I have found the ROM images on my drive. They do exactly what I have written above, nothing else.

Therefore the card is working now and you can use the extra RAM under DOS? Great! Can you please post all the jumper settings for future reference?

Does not look that bad. Your card seems to have 2mb onboard. The screenshot Shows 512kb is ok, indicated by the blue 0000000... The 45080008 indicates some error. For me it seems only the Last 512kb is working. I would remove all ICs except the ones in bank 0 first to locate the error. Then run …

This one looks similar, but has 2 DIP blocks https://forum.vcfed.org/index.php?threads/qua … am-board.74375/ Did you read the thread from the beginning? If you dont find any information about the card run testext.exe first to get the current configuation.

There is no need to mess with the KBC. Try a spare from any 286 386 486 board. 27c512 for the main BIOS is fine. You need to make sure to fill it with multiple copies if its bigger than the image file.

Is this 8088 or 8086, cant see on your photos? For me it seems all tests are OK and it tries to boot - but it doesnt detect the floppy? I would try to insert a ROM-card, i.e. XT-IDE and verify its executed.

Please upload a copy of your current BIOS. We can see if the checksum is OK and if yes try to get it running in PCem.

I think chances are high if you take a program like ATSETUP.COM and replace all references to port 70/71 with 03E0 / 03E1 you will get something useful as this seems to be the same RTC than in a AT with a different port?

So I am quite sure the sub at C538 is for reading data from CMOS (Port 03E0 / 03E1). The data to read is given in AL when it s called: F000:C51E BAE003 MOV DX,03E0 F000:C521 EE OUT DX,AL F000:C522 EB00 JMP C524 F000:C524 EB00 JMP C526 F000:C526 42 INC DX F000:C527 EC IN AL,DX F000:C528 C3 RET F000: …
