Quadruple Boot System

[Greg Hamilton]

I have OS X, OS 9, YDL 3.01 and Debian installed on my iBook. I 
sometimes use MOL to run OS 9 and OS X from YDL. Haven't installed MOL 
in Debian yet.

This is the way I have things laid out at the moment. Bit of a dog's 
breakfast unfortunately.

Install OS 9 first. It creates a bunch of little partitions (hda1 - 
hda8) which it requires to boot.

I made the mistake of putting OS 9 and OS X on the same partition. 
Yaboot and MOL both have problems with this and when I change the boot 
OS for this partition it changes the Open Firmware default boot volume 
so no more yaboot.

hda10 is a bootstrap partition which contains the yaboot boot loader. 
If I boot this partition the yaboot menu is displayed and I can choose 
to load MacOS from hda9 or YDL from hda11. If I'd installed OS X on a 
separate partition I'd be able to choose Linux, OS 9 or OS X from here. 
You should be able to add your OpenDarwin partition to yaboot as well, 
though you may have to identify it as a second OS X partition in the 
config file. Can't remember.

hda12 is my Linux swap partition.

hda13 is a second bootstrap which I use to load Debian which is on 
hda14.

Initially I installed Debian without a bootstrap partition as I assumed 
I could configure my existing yaboot to load Debian. I wasn't able to 
get it working. I think yaboot was trying to load the Debian kernel 
image from the YDL volume. The configuration I was hoping for is almost 
certainly possible but I couldn't figure it out.

If you bugger up your boot loader setup don't forget that if you hold 
'option' while booting OpenFirmware displays a list of the available 
bootable volumes for you to choose from. Boot into YDL, run ybin and 
your back in business.
