Anybody know how to netboot Debian on a PowerMac?

[Rick Thomas <rbthomas@pobox.com>]

I'd like to setup a PowerMac to run diskless.  (I know, disks are  
cheap -- this is just for fun.  Also, it's a dry-run for a non-powerPC  
system that really does need to run diskless that I have been asked to  
set up for Work.)

I know I'll need to provide a dhcp and tftp server (I'm planning on  
using dnsmasq for both), and I'll have to boot via Open Firmware.  But  
the details are a mystery to me.

Questions:

1) What files do I need to put in the tftp directory?

2) What options do I need to specify in the DHCP reply?

3) Can I do an install completely over the network -- no CD?  Same  
questions as (1) & (2) for the install.

4) What exactly do I need to type at the Open Firmware prompt in order  
to get the process started?


Thanks in advance for any help!
