I looked but did not find a full manual. You are lucky to find jumper settings on many old 486 boards. Maybe someone else can dig deeper and find it though some of the full manuals are lost forever...

Thanks for checking! Yeah, I am prepared to accept that, but I figure it HAS to exist somewhere. And I know this mobo is a bit known, so hopefully someone turns up with it.

I had a look but I don't seem to have it (was fairly unlikely for me to have the actual paper manual though but was worth a look 😜 )
Only thing I could find was this here:
ftp://ftp.aopen.com/pub/tech/jumper/
The site is (still) up and it has the jumper settings of the VI15G listed there as well along with many other contemporary boards.

The VI15G is kinda an oddball in a way because (afaik all of) these had gold plated SIMM sockets instead of the silvery ones that virtually all newer boards have.

Oh man! Awesome! This is nice to have, saved the file. I'd rather see something directly from Aopen rather than another site, so that is reassuring. And, thanks a million for checking for the paper copy as well!

Tardy to the party, but that AOpen ftp link didn't work for me. I found this:
https://stason.org/TULARC/pc/motherboards/A/A … -486-VI15G.html

It has jumper setting info. I needed something to compare against as my turbo button was behaving like a sleep button and want to understand how the turbo button was intended to work on my model.
That discussion is here: Turbo button on 486 acts like a 'sleep' button

Hope you got it working!

I owned this board over 25 years ago. I got it second hand from a friend of a friend. I am pretty sure either it came with the manual, or I had the PDF manual for it. The board is long gone, but it's possible I might have the pdf manual on one of my burnt CDs from the late 90s. I'll try to have a look. No idea if my current drive can read my old discs. I had no idea this manual was MIA.

I found this somewhere, files dated 1999...has more info than the FTP files..

I checked my old files today. Didn't see any motherboard manuals.
If I stumble across it later I'll post it here later.
