Paul,

Time for the multimeter I'm afraid.

You're in Smithsonian country.

My apologies, I forgot to mention its still connected & working. I just
don't want to go yank the connections without knowing where they belong - I
am/was intending to move the board into another case.

I'd get all excited, but Google search is useless right now.

I did, and again found that out. :-( Not that DDG did any better (less
cruft though).

Bing.com gave me this for example. I'm not expecting to find your exact
board, and the purpose of showing this is to "show what DFI was thinking".

:-) All I see there is the names of motherboard related connectors randomly
strewn over a white page. A nice example of how /not/ to convert a PDF.

Note that ODM boards, made by DFI for FS,

Facepalm. That "for FS" only now made me realise that thee "-FS" on the
end of the motherboard ID is short for "Fujitsu-Siemens".

do not have to follow retail motherboard conventions.

Which is, to me, another good reason to get the exact specs. Although
none of the frontpanel stuff is going to supply current on those pins,
connecting two output pins to a simple LED will be confusing. Worse:
connecting the powerbutton over them could destroy either pin. :-(

Thanks for the searching and links though.

Regards,
Rudy Wieser
