I have this ISA 486 board here which I pulled from a complete system, and it doesn't POST at all. In fact not even the PSU will spin up when attached to this thing, which is probably not a good sign.
Physically it looks perfect, and the system I pulled it from was in fantastic condition. There's no battery damage, etc. I've tried different CPU's in it, pulled out all of the socketed chips and re-seated them, etc, but all I ever get is a quick flash of the green LED down near the cache chips and then nothing. No beeps from the speaker.
My last hope was that the jumper settings were wrong, but I've found this stason entry based on the "486UF" on the board and they all look fine:

There are some undocumented jumpers though, so I was wondering if anyone here has any ideas, or even experience with this board?
