Apple xserve : how to boot YDL from the cd-rom drive?

[jfaslist]

Hi,
We have a Apple Xserve G5 cluster node, with a cd-rom drive, but without 
graphic nor keyboard.
I have downloaded the yellow dog 4.0 CD-ROM ISOs and want to install 
that distribution on the xserve.
I am able to get at the openfirmware prompt, over the serial port. I 
have tried to use the boot command but couldn't find the  right 
invokation. Using SPARC systems with OBP firmware, I do "boot cdrom" and 
that's it. I was hoping to do the same  here.

Is it possible to install linux by just using the OpenFirmware console? 
If so how can I do it?
Is the YDL 4.0 supposed to work on the  xserve G5?

I have found the following links but they  don't seem to apply to mycase.
