Sometimes, the drive doesn't appear in the bios, but boots. It is working fine, however, there are strange things. I didn't really notice anything bad, all the new hardware parts, airport, etc were detected instantly.
Only the booting is slightly longer than usual.
I was able to boot the system, and I can use it now, it's not really slow at all for general usage. Then, I was curious, how would my PB react to this new situation with a -supposedly- bootable version of 10.4 on the usb drive.Īnd, tadaa, as I went into the bios, the drive showed up ! I wasn't able to select it as a startup disk, either. I have tried booting the mini from the external drive, and it did not work.Įven if i held down the option key, the drive did not show up in the bios. I borrowed the mini, did the backup, and in SuperDuper, all of the booting related options were greyed out. Then, I have stumbled upon this site, and with SuperDuper, I have made a complete backup of the neighbour's mac mini. I was told by apple tech support, that booting off the external drive is impossible on g4 computers. I had a PB G4 with a dead internal hd, and I have bought an external usb 2.0 drive. My system is running 10.4.8, so I'm not sure if this is a 10.4.8 feature, a SuperDuper! related thing, or if it has to do with some other factor, but it works, and that's all I care about. But for recovery purposes, this could be invaluable. OS X booted successfully off of the external drive, albeit slowly. It showed my internal drive as well as my external backup drive as valid boot drives, so I chose the external drive. Today, just for fun, I rebooted my PowerBook G4 with the USB drive connected while holding the option key to load the boot drive selection menu. I backed up my internal drive to an external USB 2.0 drive using SuperDuper! (a great application, by the way). This hint talks about getting a PowerPC Mac to start from a USB 2.0 drive, but it involves messing around with the system's NVRAM, which can be a complicated thing to do.īut today, I tried something new. This isn't so much a hint as much as a discovery, but it could be useful to someone.
