There's some goofball firmware restriction that bootable drives on the Beige must be set to "master". You can boot a "slave" CD only using XPostFacto's "helper disk" boot process whereby the boot starts off on a master device, and is then transferred to the slave device. If you have only one bootable CD and one bootable HD they need to be on separate busses and both set to master. The Rev.A ROMs don't even support slave devices at all, so they both must be master for Rev.A ROMs. For Rev.B & C you'll need to be sure the CD drive is set to master if you want to boot it directly using the "C" key or with startup disk. I normally left my CD drive set to slave and used XPF to enable slave drive booting on those rare occasions I needed to boot a CD. Alternatively, XPF's Helper Disk boot can also enable booting from Firewire devices, so a FW CD is also a bootable option. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed Low End Mac's G3-5 List, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.
