or if Address 11 or Data 7 are not connected somewhere That's actually quite likely... Do a diode check with a multimeter (the cheapest 5$ Aliexpress / Poundland / whatever model will do), putting red at A11 and black at +5V, and a second check putting black at A11 and red at GND. If neither of …

Do you have an eeprom burner? You may try Mr BIOS That's another idea. I've also found some additional M321 BIOS .BIN files. I *might* be able to scrounge up an EEPROM burner-- I have a friend with one but he hasn't seen it in ages so it's probably buried under anything/everything right now. I …

I have an M-321 rev 2.6 (or 2.7?) board and recently acquired four 30-pin, 16MB SIMMs, hoping to bring it up to 64MB or potentially 80MB by having four 4MB SIMMs in the other bank, but the RAM counts up to only 16000 bytes with those 16MB SIMMs in either Bank 0 or Bank 1 and the other bank left …

Make sure VIDE-CDD.SYS looks for the drive on the right IRQ and port, so be sure you're setting the /P switch for that driver line correctly: /P:168,10 . CDSETUP just activates the IDE port, VIDE-CDD.SYS then looks for a CDROM drive attached to the port you tell it to look. https://www.vogonswiki. …

You haven't specifically said if the drive is assigned a letter in DOS. For a CD-ROM drive, it's not enough that the BIOS enumerates it-- it needs a device driver (such as SBIDE.SYS or CDMKE.SYS or any number of others depending on drive) and a network redirector (the latter typically being MSCDEX. …

You may need to register the .DLL by opening an elevated command prompt, changing to the \windows\system32 directory and then issuing the command regsvr32.exe /r dllfilename.dll But if it's not a 32-bit .DLL, it probably won't be able to be loaded because of the removal of the 16-bit subsystem.

From the collecting point of view 386sx is interesting to me as "a last 16 bit x86 cpu". I read somewhere it really is 32bits internally, but with only 16 bits exposed. This makes no sense to me at all. If it really is 32 bits internally than what is the difference between 386sx and 386dx? Just the …

I honestly never understood the point of the 387sx The point of the 387 (whether S X or D X is to provide floating point operation to the system. All it does is floating point; it does not replace the 386 itself. Are you thinking of the 486SX/487SX (in which the 487SX is just a 486DX that takes …
