You have two options here: PC style partition table with a small hfs partition on (or fat12 but you'll have to change the yaboot.conf string and rebuild yaboot) Mac style partition with Apple_Bootstrap and an ext2 partition. I've done the latter, attached is a script I used to create a USB image. You can do this in OS X too using hdiutil and friends (disktool, pdisk). Some macs seem to be fine with finding the USB device and displaying it in the chooser (hold down option on boot), others weren't. If yours doesn't you'll have to find the device in OF and boot off it. Also attached is the ofboot.b and yaboot.conf used - the kernel and ramdisk are from FC4 ppc. Tested with OS chooser on a dual G4 PowerMac (yiou get a disk icon with penguin and usb icon below). Select disk, click -> arrow. Using fedora core 4 - note you'll have to setenforce 0 as selinux doesn't allow partitioning a file otherwise. device was /pci@f2000000/pci-bridge@d/usb@9/disk@1 The above booted fine got to yaboot and booted kernel. hth Paul
