I've been running Leopard on my PowerMac G4 (Digital Audio). When I originally installed it, I used Firewire Target Disk Mode to do the install. Now I need to do a re-install to fix some errors from the 10.5.6 update, but since my MacBook Pro only has FW800, and my cable is 6pin-6pin FW400, I'm trying to use OpenFirmware hacks to install it directly. I used the hack used by LeopardAssist to set my processor speed (at least as reported to the system by OF) to 867MHz, and the system booted and I was able to launch the set-up application. Unfortunately, this system does not have the required amount of RAM, and I don't have any PC100 just lying around. Is there any way to use OF to fake the amount of physical RAM I have installed? Or would that assign memory addresses to RAM that does not exist? Thanks for your help.
