Re: ppc USB boot
Thanks! I'd heard rumours of usb boot workarounds before but never the recipe.
I've done lots of firewire target mac installing (saved me a couple of times) but got nowhere aiming Linux ISOs at mounted FW targets trying from OSX Mtn Lion, getting less Unix all the time.
G4/5 = Leopard-max / G3 Tiger-max, ppc needs Linux or die. These ATI cards are useless for video but 1.42 & 1.25 GHz are still half-decent machines, G5s can still do some heavy lifting. My G3 is more like toy status; I just reinstalled OS9 after a LVM install claimed ownership: what a blast from the past! (y2k) lol All this info gives me incentive to try again to get the DVD-less testing, do what I can to keep ppc demand for distros alive - wish I'd gotten the 13.04 radeon cards tested in time to file better bug reports ...next time, thanks again
