i have a 1998 seriex powerbook g3 with 3 OSes (OS 9, OS X, and LINUX) i know there is some way for the mac's open firmware to be configured to present a nice little menu to select the OS, but i'm not sure how, does anyone know ANYTHING about this? the OF version is 2.0.2 i think
Also, I think if you hold down the Option key when your computer starts up, it will list OS's that you have loaded, but a) I think it lists only one OS per volume, and b) I don't know if it will recognize Linux.
