USB boot is different on PowerBook. Download morphos.iso and put iso image and mac_ppc32/boot.img to your pendrive.

boot ud:,\boot.img bootimage=umsd0:morphos-3.1.iso

(bootimage keyword can be shortened to bi)

Just in case someone doesnt know: to get an access to OpenFirmware on Apple machines hold down apple + alt + o + f keys.

(FAT32 partitioning is assumed. I dont know if Apple firmware supports USB boot from any other common file systems there. Amiga file systems certainly are not supported there.)

It is also possible copy all files to USB pendrive and boot using bootdevice argument. For install/update purpose using iso image is certainly better.

Where is the directory for mac_ppc32boot.img?
Where on the pen drive do you put the iso image and mac_ppc32/boot.img?

Boot image is inside ISO image. Copy both boot image and ISO image to the root directory of your pendrive, hold down apple + alt + o + f keys and you get open firmware console where you can type boot command.

FAT16 probably works.

Morphos on my MacMini booted from a USB FAT32.
The whole system was copied from the ISO.
Boot.img for MacMini just moved to the root.

Previously you should check whether OF sees pendrive.
Top list the files from the flash drive.
