Where are the Panic.Logs?

[0xbaadf00d]

I am unable to find the panic.log file, and nvram - p of course does not work either.

 

Where did the panic.log go, or how can I generate one?

 

Thanks

It doesn't exist and you can't create one. This is because when the kernel panics, it saves the panic information into nvram, from where it is retrieved and logged at the next boot. But the x86 BIOS doesn't have nvram, so no panic.log. But you can boot with debug=0x100 to have the panic information dumped to the screen.

Thanks. But how do I boot with debug=0x100? nvram to set the boot options is not an option either... :-/

 

Thanks

Just like you would boot with -x or -v: When the Darwin boot loader asks for any key to enter boot options, press any key. Then, at the kernel command line prompt, enter debug=0x100 and hit Enter. You can enter almost anything you would put into boot-args on a PPC at the Darwin boot prompt on x86.

Forgive my ignorance, I have never seen this Darwn Boot loader. How do I activate or access it?

 

Thanks

1. Turn on your computer.

2. Wait for the BIOS messages to flash by.

3. As soon as it says something like press a key for startup options, and starts counting down the seconds, press a key.

3a. If you don't get this message, start over, and press Shift (for example) when the BIOS messages have almost finished flashing by.

4. At the prompt that appears, enter "debug=0x100", without the quotes, and press Enter

5. Wait for the kernel panic.

6. When the kernel panics, it will print some lines of text onto the screen.

When I turn the machine on, I see no BIOS messages flash by. I just see the grey screen with the white Apple and the progress indicator.

 

Probably I should note this: I may be the only person on this board, but I am running OS X on a DTK, not a standard PC,

Completely off-topic, but many of us wanted to know, does the mac chime when you turn it on?

That's what we need created. I want to hear the chinme and the car crash. But we diffently need some type of panic log. Maybe the next update will have one.

OK, that explains some things. Sorry for my last post then. Well, I guess you should get a prompt or something by pressing some key combination when turning the box on. How do you activate verbose boot, or single user mode? Well, there has to be a way to set kernel debug flags. This is a development machine after all.
