Hi All, Thanks to everyone who provided some advice. I just wanted to report back with what seemed to work in the end. It was a combination of all the different advice I got. Recall the partition map: ... 10: BootX (HFS+) 11: / (root) (UFS) The working set of OF variables is: boot-device = mac-io/ata-4@1f000/@0:10,\\:tbxi boot-file = mac-io/ata-4@1f000/@0:11,\\mach_kernel.new The odd thing was that boot-file had to be the explicit device path and none of the device aliases that name the same device node. My guess is due to the fact that OF loads BootX from partition 10 and BootX then looks at boot-file to find the kernel. I'm not quite sure why it can't handle a devalias. Thanks again!
