Machine boots directly into Mac OS X with no yaboot boot menu

[steve s]

Hello again

I have been able to get linux to start by in 2 different ways.

The first way is to insert CD 1 of the yellowdog linux 4 CDs and hold the 
"C" key until the machine boots from the CD. The installer appears with all 
the usual installation options as well as the two yaboot linux startup 
options I made. I get into linux fine through here by just selecting the 
linux starup option I had set as default (2.6.10-1.ydl.1 kernel).

The second ways is by following the instructions at this web site:

http://penguinppc.org/bootloaders/yaboot/doc/yaboot-howto.shtml/ch9.en.shtml

under the title "9.2 Loading Yaboot". I strt my machine and hold the 
Command-Option-o-f keys and the open firmware screen appears at the prompt I 
enter:

0 > boot hd:2,yaboot

and yellowdog linux starts.

BUT I dont want to have to do this everytime to use linux, I had yaboot set 
up and now it is gone. Is there anything I can do to get yaboot running 
again so I can choose which OS to boot each time I start up?

Thanks for reading.
