Re: Prod kernel hangs on mac mini

Thanks for the suggestion.  I did try ofwboot.elf at one point, although 
I can't recall what happened with it.  I was learning to deal with open 
firmware...

This morning when I booted it up I got an ominous sound: three beeps.  
This apparently means bad RAM, so I started to think maybe the problem 
is my hardware.  However after opening it up, vacuuming it out and 
re-seating the RAM , it seems OK at least according to apple's hardware 
test.

Meanwhile I also picked up an iBook G4: trying to load 9 on that leads 
to a very similar problem; it runs the install OK but doesn't boot the 
installed kernel.  This time it doesn't enter a loop trying to load ddb, 
just hangs after the 4x memory region lines.

However, I had more success with 10-rc1.  The iBook installs and boots 
into the system.  Progress!  Also the mini has just installed the rc 
version, and I booted into that too.

Now I'd like to work out how to get some extra software installed, so 
learning about pkgsrc...

Thanks,
Alex
