I have this WD 90c33-zz that has no video output when used in my 486 pc. I am going to replace the VGA port because it is corroded, but I am wondering if anyone knows the correct jumper settings or has a copy of the manual.
My 486 pc is known to be working, and has a 486 dx4100 and 16mb of ram. I have removed most of the other parts including the soundcard to see if it would work without, but it did not.
I have attached some photos, one of which I have circled the locations of the jumpers. There are a few, and they are labelled:
JP4 (which is a connector)
It is possible for this board to have switches, but they are not installed. It is also possible for this board to have 2mb of ram, but it only has 1mb.
