I believe that the correct sequence to reset the pram is ctl-option-p-r rather
than apple. 
Showing my complete lack of knowledge for macs but,
   What the heck is the option key?


On a 7200 there's no video output for OF, but you can access it
through the serial port.  Hook up a serial crossover to another box (I use
38400-8N1 with hw flow control turned *off* and it works just fine), and do
ctl-option-o-f while it's chiming and you should get an OF prompt on your serial term. From there you can setenv boot-device appropriately and that might get you up and running without zapping the pram. 
OK, thanks for the info hopefully I'll be up and running tonight.

Hopefully that's all correct and slightly useful. =)

Hi,

I inheritted a PowerMac today - no OS and set about installing Debian on it.
Booted from floppies and installed from NFS.

When the question "Make Linux Bootable Directly From Hard Disk'' came up
see sec7.17 http://www.debian.org/releases/2.2/powerpc/ch-init-config.en.html 

I followed the instructions.
  ``Execute a Shell'' and run:
           nvsetenv `ofpath /dev/sda2`

replacing sda2 with sda5 (main linux root partition)
After hunting the mailing list I beleived I should type nvsetenv boot-device `ofpath /dev/sda5` 
So I did. I then followed the instructions to reboot.

Now on restart the monitor goes into sleep/suspend mode.

ctrl+apple+reset reboots the machine but I can't get any furher.
I have tried ctrl+apple+p+r but that does nothing - (during power on/reboot...)
I'm lost as to how to solve this - I'm new to macs but am fairly familiar with the prom from Sun machines. 

Could someone give me some pointers?

I'm not on the list so please CC any responses to me.

Regards,
  /James
