Here's some fun infor for all. I finished my I-opener project and got my cheap portable device, so when I saw this I ran out today and was lucky enough to get one for $49, no TOS. 2 others in my office all managed to get theirs from compusa in Nashua, NH. The one in Salem started TOS'ing and one guy was not lucky enough to get one from there.
Anyways, on to the fun.
I got the spec for the SuperIO chip from National Semi: http://www.national.com/ds/PC/PC87317.pdf
I decided to see what was hooked up. I decided to look for the IRDA since it might be interesting, and I finally found it. It is located on the CN28 connector (front left of MB). It is currently half used. I found the following pins:
Speaker (as labelled) pins 2,4,6,8
IRDA pins 1,3,5,7,9 are as follows: +5, IRRX2 (pin 79 superio), IRRX1 (pin 80 superio), GND, IRTX (pin 81 superio)
Also of interest are: pin 8 +5 and pin 14 GND.
I also managed to ohm out, but don't quite know what it means: pin 11 is Battery/help voltage (Not really sure what it means or which. and pin 13 is switch_bar (pin 66 on superio) a momentay switch to GND will signal ACPI that you wish to turn power off. My guess from glancing at the docs is that pins 8-13 are for suspending etc... and providing a status LED from one pin.
This is all ohming out and specualtion at the point. I don't have a hard drive in yet, I'll let you know if I can try any of it. Questions I still have are:
What is the IC card interfaces (TTL and RS232), standard COM ports, or something more fun. and what other neat things can be done. The super IO supports floppy drives...
