yaboot: multibooting problems

I bought my systems used. $200 total for: a G3 B&W, a G4 Quicksilver, and a G4 iMac. I spent $83 on a used SunBlade 1000. Do you know where I pick up my spare parts? In the trash, in dumpsters. My "elephant in the kitchen" is that I am poor.
I did not spend all of $283 in a single day. It was over a period of a year.

The PowerPC systems that can virtualize are way out of my price range even for the used ones.

What I asked for was help in making two systems bootable.
I've dd'ed ofwboot to a bootstrap partition before OpenBSD.
I haven't done anything outside of installing NetBSD.
The Open Firmware disk paths are easy.
Which partition on hdb is easy.
How to place ofwboot.xcf, ofwboot, and ofwboot.elf, where to place, and how to get OF to boot indirectly through yaboot is not.

Although this may not be the answer you are looking for, have you considered virtualizing some of the operating systems? Although PPC does not lend itself well to that task, the idea that you are running that many operating systems, to me at least, suggests that it might be time to solve the larger problem, rather than just working around the elephant in the kitchen.

## yaboot.conf generated by debian-installer

## run: "man yaboot.conf" for details. Do not make changes until you have!!
## see also: /usr/share/doc/yaboot/examples for example configurations.
## For a dual-boot menu, add one or more of:

## bsd=/dev/hdaX, macos=/dev/hdaY, macosx=/dev/hdaZ

device=/pci at f2000000/mac-io at 17/ata-4 at 1f000/disk at 1:





What does not work:

>boot hd:6,ofwboot.xcf /bsd

>boot ultra1:6,ofwboot.xcf /bsd

>boot /pci at f2000000/mac-io at 17/ata-4 at 1f000/disk at 1:6, ofwboot.xcf /bsd

I've dd'ed ofwboot to hdb5.

Not sure as to how to enter the information into yaboot.conf.


Sorry about the copy and paste from another mailing list but, there seems to be no one and very little information as to setting up my system.

I have debian, netbsd, and oipenbsd installed on the machine, each has a bootstrap partition before it.
I have room to install freebsd.
I have space left over- 60G- for one more system.

The freebsd bootloader is recognized by open firmware, netbsd and openbsd do not have such available.
I found an email from 2001 by ??@alaska.net on multibooting with netbsd.
