[LinuxBIOS] alix1c

[Peter Stuge]

Limited success.

LinuxBIOS-2.0.0.0Fallback Fri Nov 16 05:46:41 CET 2007 booting...

I added a POST code and a while(1) near the end of hardwaremain.c
after this message. The board shows the POST for about a second and
then powers off.

If I move the while(1) to after init_timer() it pauses on POST 11 for
a second or so, then shows some other codes quickly, then 80 and
then power off, even though init_timer() seems to be do {} while(0)
on the alix1c. This is also the behavior I get with a fresh checkout.

take the jumper off the power pins, It is delivered with the jumper on.

Hahaha! Lovely! =) Thanks.

I did not think about this at all because it does not behave the same
way with the onboard BIOS. Does anyone know what can be done to
appease the hardware into _not_ shutting down even though pwrbtn is
held pressed from boot?

See this:

and its thread.

LB is programming the power button to shut down after 4 seconds. If you 
don't want it to shut down *don't do that* :)

Thanks for even digging it up for me!

Check. :)

I think I will add a new option for this.

Be careful with that - the failsafe is generally considered be a pretty
valuable addition.  I can't think of any pratical reasons why you would
want to not have the failsafe.

Even in this case, it wasn't the failsafe that was to blame, though it was
what was giving you heartburn.

I stand corrected - there are indeed some good reasons why you want the 
power button wired to ground.  Carry on.

Yes, there are some no power button (instant on) implementations that 
are interesting for Geode systems. Peter's patch will be a good addition.
