Thanks for the direction. Pretty much what I figured. I've been reading
some of the forum postings. Being an old assembly language programmer, it
might be fun to get back into a project like this. I have a Canon S410
along
with the SX100 so I could play with two different platforms for a while to
get aquatinted. FWIW I did get ver.req working on both cameras.

Thanks again.

That's a start! Getting ver.req to work, at least that a sign of
viability. Now
if you can get a firmware update option to show on your menus by putting a
*.fir
file in the root folder of your memory card, it's more than likely
possible. Use
any of the pre-existing ones to test it, it won't harm the camera, you
just want
to see if you can get a firmware update menu option while in playback
mode.
That's the snag that S5 IS and some other Digic III models have run into.
Canon
changed either the filename recognition or firmware update method. It
might be
nothing more than just a change in the filename extension from *.fir to
*.frm to
get the camera to show the firmware update menu. Nobody will know until
they
stumble across it. That first kite-string across the canyon has to be
there
before you can run the cables across for the main bridge-building task.
It's
there, it's just a matter of finding it. Winter is coming up. I'm sure
some
bored S5 IS owner will press enough buttons during start-up and try enough
different filenames during commercial breaks while watching movies. Or
they'll
just study all past firmware update procedures used on all cameras and
find it
that way. What they find can then be used on all the other Digic III
cameras
with a similar drawback. Just the challenge of finding it can drive
someone,
knowing it has to be there, even if they don't want it for CHDK.

Too bad that Canon can't recognize the superiority and full potential of
their
cameras that allow CHDK on them and how much that could increase sales on
all
newer models. Instead, their "intelligent"? execs took the paranoid route.
They
could do with a good corporate psychologist and some anti-psychotic
medication
in their water-coolers for that problem. :) They wouldn't have lost so
many
sales on the S5 IS. Just another sign too that Canon doesn't care one bit
about
what their customer wants and needs. You have to buy what THEY decide you
will
need. A most juvenile and insecure PR department if I ever saw one.
Typical
insecure, childish, male-ego control-issues destroying their own futures.
It
hurts them on all fronts if they don't want to play along. Their loss.

Again, good luck! Looking forward to seeing SX100 IS and S410 listed on
the
compatible cameras list.


I downloaded and installed a ps.fir file on both cameras and no joy. But,
I'll keep tinkering.
