I've got a DMG for 10.6 that I could use for rescuing a MBP...except the DVD drive is DOA. I've read many writeups on installing later OSX versions to a USB stick that is bootable, but have not found a working solution for 10.6 flavor. All the writeups talk about locating the InstallESD.dmg buried within, but I've not found same inside 10.6's DMG. I tried just copying the whole DMG over with CCC. That got me a USB that the machine OK's as a bootable volume, but attempting to do so got me three long boops from the speaker, and nothing more. Suggestions?
