To use it, place yaboot_0.5 and the corresponding yaboot.conf files at the root level of your MacOS hard drive (or on a bootable disk). If this is your first boot (that is, you are installing Linux), you will also need the vmlinux.benh.15 kernel from ppclinux.apple.com/~benh/ (click on "precompliled kernel"). to use yaboot, restart your machine into Open Firmware by holding down Command, Option, O, and F at startup until you see a white screen with the "Welcome to Open Firmware" message and the prompt: 0 > At this point you will need some magic. Finding the appropriate incantation to get OF to find yaboot is tricky on a non-stock machine. On my sawtooth G4, I type: boot hd:,yaboot_0.5 Your mileage may vary. yaboot will load adn give you a standard Linux boot: prompt. Type the name of the appropriate image in yaboot.conf and the machine should boot. After installing, you should be able to place yaboot in its own partition using the ybin utilities (I haven't done this yet, so I can't help here.) How should the yaboot.conf file look? Well, here's what mine looks like: image=hd:1,Linux-G4 label=install-linuxppc initrd=hd:1,ramdisk.image.gz initrd-size=8192 novideo image=hd:1,Linux-G4 label=debian initrd=hd:1,root1440.bin initrd-size=8192 novideo explanation: image is the name of your kernel (in OF notation - /dev/whatever notation won't work!) label is name of this boot method initrd is optional, and specifies the name of the boot ramdisk (for install only) initrd-size is the size of your ramdisk in memory (8192 seems to be standard) novideo indicates that the kernel should use the Open firmware-initialized video, rather than initializing video itself. Try it both ways and see how it works. This should be enough information to get you up and running... Oh, and thanks to Ben Herrenschmidt for all his work on the Linux kernel for PPC and getting it to boot. You've done a wonderful job! Jason
