updating yaboot

[Raymond Born <ipcray@comcast.net>]

I am a Linux beginner with a Mirror-door Dual1GHZ.

I have tried endlessly to get both Mandrake or Debian Linux to boot on 
this system.
I have 3 drives, 2 in the ATA-100, 1-ATA 33 (Linux Drive)  in the ATA 
66.

I have properly partitioned and installed.  This last time I did not 
even install 1.3.6 yaboot onto the apple bootstrap, knowing I need 
1.3.10 to work on my machine.

How do I manually install yaboot without being able to see that drive 
from OSX?  Can I see it from OS9 or some other means?

I have extensive overall computer knowledge in both windows and macos 
environments since the PCAT and Apple IIe.  I have no Linux experience 
at all.

Please help.  35-40 hours and nothing but a white screen at startup.
