I am trying to configure the Open Firmware (OF) NVRAM settings such that Linux is booted by default, but I can't make it work Can anyone help? I have 2 IDE disks. ide0 is used by MacOS and ide1 is for Linux. The root partition is on ide1 (hdb5). I followed instructions in the LinuxPPC Installation Guide but when I try to boot, OF displays boot MAC-PARTS: LOAD (interposed) not supported load-size=0 adler32=1 What is this message telling me? Is the machine still trying to boot MacOS? I set the following variables using the OF "setenv" command:- boot-device ide1/disk@0:5 boot-file ide1/disk@0:5/boot/vmlinux root=/dev/hdb5 hda=noautotune hdb=noautotune boot-command dev ide1 cr set-timeout 0 cr boot load-base 0x100000 (and 0x4000, 0x60000, 0x10000...) I guessed that ide1, partition 5 would be represented as ide1/disk@0:5. What does that @0 represent? Perhaps I need to set other variables? OF displays its versions as PowerMAC1, 1 1.1f1, Open Firmware 3.1.1. I also noticed that the LinuxPPC "nvsetenv" command doesn't display that variable values as listed above. Effectively, any changes to boot variables I make with "nvsetenv" seem to be localised to the Linux environment; they are remembered between reboots, but the values are different to those displayed by the OF "printenv" command. It's as if the OF "setenv" command and linux "nvsetenv" command modify different copies of the parameters in NVRAM!!!! Is anyone else seeing this?
