On the Dallas web site (or maybe the related, i-butting site),
I found an RS232 <-> 1-wire interface that attaches directly to
a DB9 or DB25 serial port. They're obviously eager to promote
this protocol because the plug-in interface was only about $10.
There is also free interface software available for downloading
(MS-based, Linux-base, microcontroller, even Palm Computing and
Handspring's Visors!), so maybe this little fishing expedition
won't be as difficult as I thought.
The program posted by Tom Trottier looks very interesting.
*** Thanks Tom !!! **** I wish I knew who wrote it or whether
it came from IBM as a fix to a common problem. But it makes
sense, if the laptop can update a charge counter in the pack
then it can probably reprogram the other memory locations.
Hmm... is it done through a special bios call?
