Q: how do i install and boot mac os 10.4 on a usb flash drive?

USB drives generally aren't bootable on PowerPC Macs such as yours.

At some point in the past, when the hardware was more recent, some said they

were able to make it work. To boot a PowerPC G4 iBook (USB2.0 ports) from a

USB flash drive memory device. The read/write speed of the USB flash had to

be optimal and the capacity large enough to accommodate the booting and also

the necessity for Virtual Memory to run on the USB flash drive, as with a HDD.

Some suggested they made a clone of a working system, boot from USB flash.

There still are some bits and pieces of information pointing to discussions or

other topics of similar concept; some of the older sites aren't online any more

where claims and 'proof' were given that this worked out OK. Figuring the older

Apple portables were adapted to use CF or other camera memory cards, for use

in systems prior to OS X...

Sounds like a fun diversion, to take ones mind off weather, and other incidentals.

Its not worth the trouble making a bootable usb version just use the cd i would suggest
