Hello all,

I've been given an old tower made by Fujitsu-Siemens, with an NS30/35/36-FS
rev-C2 motherboard inside, which seems to have been made by a company named
DFI.

I have already found some data about it (max processor speed, type of memory
used, etc), but I'm missing one important part: the physical layout of all
connectors, and especially the description of the pins of the headers (onto
which the frontpanel stuff - buttons, leds, etc - is connected).

I've ofcourse also tried to search the DFI companies site, but probably due
to the motherboards age (2003) the info (and downloads) for it seems to have
been purged. :-(

tl;dr:
Does anyone know or have (a link to) the "how to connect" guide to an
"NS30/35/36-FS" (rev-C2) motherboard for me ? TIA.

Time for the multimeter I'm afraid.

You're in Smithsonian country.

I'd get all excited, but Google search is useless right now.
Google and Bing used to give almost equal results. Now,
bing.com is beating them a bit in terms of pages returned.

Google used to do "load shedding", which is why I had to tell
people occasionally it could take 24 hours to find a breadcrumb
for them. It's a lot worse now.

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".

Front panel header example.

Note that ODM boards, made by DFI for FS, do not have to
follow retail motherboard conventions. A retail motherboard
from the era might have up to 20 pins for the panel header.
Whereas ODM standards are to use an 8 pin pattern, with PWR/RST/IDELED/PWRLED
type functions.

On page 20 for example, pins 3,4,5,6,7,8,9,10 are the
ODM subset of pins. Two switches, two LEDs. DFI could simply not put
header pins into the other holes, to satisfy FS as a customer.

And the Green Switch might be a Sleep button, but I can't
be sure of that. PCs have had more than two switches on the
front, but I don't know what that was for. They also had
Power LED, IDE LED, as well as Message LED, where Message LED
might have lit up when an email poll picks up new mail. I don't
think I've owned a PC with that on it :-)
