Easily boot from USB 2.0 drives on PowerPC Macs
Authored by: bjsvec on Oct 24, '06 07:54:23PM

This didn't work for me. I have an iMac G5 1.8ghz running 10.4.8 and an Iomega 250GM USB drive.
I tried it with bluetooth keyboard and usb keyboard. Both let me hold option to get boot menu, but all I see is my internal drive and I don't even seem able to select that. I see a reload icon and a right arrow icon and the drive in the middle, but the arrow keys don't do anything..

Is there something that needs to be done to set the external drive as bootable to be recognized on this menu?

Use the appropriate tool to copy the System files to the external drive and use the mouse to select it in the menu that appears when you hold down the OPTION key during boot? =)

Sometimes if volumes don't appear in Startup Manager (what you get when you hold down the Option key at startup), you need to reset the Mac's PRAM, NVRAM, and Open Firmware. Shut down the Mac, then power it up, and before the screen lights up, quickly hold down the Command, Option, P, and R keys, until the Mac has chimed twice more after the powerup chime. Then, before the screen lights up, hold down Command-Option-O-F until the Open Firmware screen appears. Then enter these lines, pressing Return after each one:

reset-nvram
set-defaults
reset-all
