Reset Button

I can't remember if I read it here or somewhere else, but I half remember someone mentioning that you can re-program the reset button through one file somewhere (in /proc maybe, can't see it though). Did I make this up or what

If I didn't can you put anything you want in there?

cheers

This is not possible.
The reset switch is not software related.

The reset button on the front of your PC will ALWAYS reboot the machine. However I believe that Linux allows you to re-program the 3-fingered-salute combination ctrl-alt-del. I think it's an X-Windows feature?

I realised that the reset button just moves the program counter back (can't remember the address now though). Should have asked if this creates some interrupt that linux could catch.

Can I change the inittab to point to any script of my choice for ctrl-alt-del??

Cheers

ca::ctrlaltdel:/sbin/shutdown -t3 -r now

change that to whatever you want. some sites recommend setting it to an echo and a log action

YAY, nice one

Cheers all!

Now, what can I have it do...

You can rewire your reset button so that it suspends you computer ... i know you can do it in Win cuz my bro has his set up like that.

Not sure about Linux.

well, all atx compatible mobos have reset and sleep connectors on them, so that's easy enough. That is, if you're case isn't good enough to have a proper sleep button already anyway.

Then again tho, Suspend To RAM support on linux is minimal at best.

So! lol, here we still are. Old thread, yes, but the perfect place.

Has anything changed as far as hooking the RESET button to make it do something other than kill instantly?
Anything I haven't found by Googling, that the newer kernels can do to 'software-rewire' the RESET button so that acpid can catch it?
Or is it really still a 'hardware' hard-wired button?
I did not see anything recorded in acpid.log after I pressed RESET, but then again, the machine reset pretty quick when I hit the button

I am about to have a look inside my machine anyhow; I have a new motherboard (6mos old or so) and seem to have fairly complete ACPI support (at least in theory). Maybe if I have no other connector to connect the RESET button to, I will just disconnect it. After all, the power button works fine, and IS ACPI-hookable.

I bloody well HOPE the reset button is hardware, I hate the feeling of something like that being programmable. What they did to the POWER button is unthinkable - to turn off my machine, I have to HOLD DOWN the button, and you can't buy a case with a switch that's a SWITCH. Why does "shutdown in windows" powering down the machine mean that I have to hold the button on the front of my case down?

In many cases (resetreset) the power button function can be set in your BIOS. There are often options like "Suspend, power off instantly, or 4-second delay".

A case with a SWITCH would be rather pointless, as the power button is a momentary SPST button, and does not maintain connectivity after being released (unless maybe the case is old as hell, and then it *may* have a SPDT switch-button). It only sends a signal to the motherboard to tell the power supply to turn on (by dropping the green wire to ground).
