aren't the analog pins connected to the dvi ones ? ie measuring continuity between the pin header and dvi pads should give easy results. since there's no backside visible i'm assuming that the dvi connector is only lacking the pins, but the pads/holes are available on the pcb under the connector and …

The topic of ISA crops up from time to time, and I wish I had bookmarked some. The problem, if I recall correctly, is that the below 16MB address space is no longer available for the pcie space, and thus also not for the pci or isa space. Virtualization should be possible, direct hardware access not …

Speccy is not necessarily wrong . If 8GB is statically allocated to the onboard GPU, I am pretty sure that one would see similar results to those shared. I think it's worth checking that before popping the hood, IMHO . Given Bitwrangler's suggestion, I'm assuming speccy might not be wrong and reads …

That´s strange, there´s no E-series that contains the value 6.0 https://www.eevblog.com/forum/beginners/common-resistor-and-capacitor-values/ and I have never seen a 6.0µF (tantalum) capacitor. Just wondering if there´s another code applying here? You are right. lousy guess of mine. Found a picture …

Please, Do us and yourself a favor and take out the ram, take a photo of the label and post that. Or if you can take a photo of the label that's on the ram without taking it out, do that.

FYI, a tantalum is a capacitor, most of the time those yellow/orangi ones, like the one marked 4µ7 35V ... not a resistor. I still have a few conner drives, maybe I have the same one as you, I'll have a look and get back to you if something turns up. edit: a quick look around didn't give me the same …

from looking at the bios file size you're looking for a 128Kilobyte eeprom or compatible. like a 27c1000 or a SST39SF010 or ... though the motherboard might also support a 256Kilobyte chip, going from the labeling you've noticed. like a 27c2000, or a SST39SF020 or ...

Have you tried swapping your memory banks around, or with just one bank filled ? I can't recall if you already tried this and am a bit too tired atm to check.
