Hello
Is there any possibility to activate the case LEDs? I mean the heartbeat and
the network activity
I have a A180 machine

Yes.
I was already asked this weekend to dig up technical info on LED
and soft power control. I guess this is my reminder to do that. :^)

Isn't there a PDC call (pdc_chassis?) to do this? Or is the heartbeat
LED done by hardware?

A couple of months ago, I asked the same question, got answer to look in the
mkLinux sources. I did, and I think it was a register (outb(0xblabla);).
Wrote a driver (and for WAX, got a Intel Flash 32 EISA running), can't
release it now, because of some copyright issues...

I think that the heartbeat LED is software because it starts with the kernel
boot and if the kernel stops the LED stops
blinking too. Is better to implement a software monitoring tool because you
have to watch the software for hanging.
Alex
PS. There is a function in the kernel source in
linux/arch/parisc/kernel/process.c named machine_heartbeat(). Any connection
with the heartbeat from the chassis?

I dug up the info but it's not in a form I'm willing to publishing.
However, someone did volunteer to look at this and I've provided them
with this info. So it will make into our CVS source tree and get
published that way.

Not AFAICT. PDC_CHASSIS is documented in the pdc32.pdf found on
http://www.parisc-linux.org/documentation.html
But my gut feeling is parisc specific code could make some PDC_CHASSIS
calls to set up "sysstat" field (eg initialize, shutdown, run states).
Does anyone know if the chassis codes used by HPUX are published?
It would be cool if parisc-linux used the same codes where possible...
> Or is the heartbeat LED done by hardware?
Code I've looked at before seems to all do it in software.
