I (alas) have no remote machine. WHat are the magic sysrq keys on a Mac?

The default is 0x69 (F13).  Read more about the Magic Sysrq here:

/usr/src/linux/Documentation/sysrq.txt

You can change the key used.  Use "showkey" to find out the keycode of the
key you'd like to use, and then change the following line:

         ppc_md.SYSRQ_KEY         = 0x69;

...which should be around line 667 of the file
/usr/src/linux-2.2-stable/arch/ppc/kernel/pmac_setup.c

Note, you must enable "Magic SysRq key" under "Kernel hacking" when
compiling your kernel.


Thanks,
