Some of you have inquired about why there is no TenFourFox 31.2.1, and the reason is the issue it fixed (incomplete pave-over installation) doesn't apply to us. I'm waiting for build tags to land and then we'll pull and build 31.3 for the weekend. I've gotten most of the new assembler for IonMonkey PPC completed, and once I get 36 aurora to work, then I will turn my attention to the macroassembler.
Finally, from the world of the Web, a primer on booting Leopard from a USB stick. This probably works for Tiger too.
Note the interesting limitation he discovered that 10.7+'s Disk Utility cannot create Apple Partition Maps anymore, meaning they can no longer create bootable volumes for Power Macs. Keep your Snow Leopard Intel Macs humming. :( Seems to work on Mavericks and (reported) Yosemite, so maybe it's just Lion?
