I'm wondering if anyone has any tricks or sources to get
GOOD data on the operation of motherboards.

Specifically, I have an older ABIT KT7-RAID motherboard
that I'm looking to have some fun with, but I need to
know more about the headers.  It has two SMB headers,
which the manual describes as "I2C compatible", and an
IR data header, which is basically a 5-volt serial port that
comes complete with its own ground and power pins.

My thought is to take Wouter's Wisp628, put it on a tiny
little board and hide it in a spare drive bay.  Connected
to that little serial port, that'll give me a slick way to
program PICs simply by having a socket on the front of
my PC, or to do ICSP by running a cable off a header on
the front panel.

Problem is, I don't know how much current I can source
through this thing, and I don't want to find out the hard
way.
