Hi Wally,

The "Kernel Programming" manual indicates that the DB_NMI nvram option:
nvram boot-args="debug=0x4"
will drop into the debugger on NMI (Command-Power or interrupt
switch), but I find that just pressing the Power alone will cause
this. Is there any way to force that Command has to be pressed as well
(I like to use Power alone to cause the system to sleep)?
On newer systems without separate reset and NMI switches, if boot-args
has the debug flags set, the power button then becomes an NMI button.
