Thanks, Bunsen. But my iMac is a Nov. 2009 model (i7 QuadCore). It won't boot from a Tiger DVD. It's times like this I get frustrated with Apple. It makes logical sense for them to severe compatibility with past OS's on new hardware, since it reduces their workload. But it's a false limitation imposed on the hardware, since 2009 hardware that can run Snow Leopard technologically speaking should have the ability to boot Leopard and Tiger too. And the end result of Apple's self-serving interests is that we the consumer have to pay for it, and jump through hoops to accomplish backward compatibility that Apple so greatly disdains. Of course, this thinking is very much Steve Jobs -- the man who saved Apple and boosted my AAPL stock price into the stratosphere. And none of us here can argue about the greatness of Apple hardware and software. It's truly a Love-Hate relationship.
Anyway, there must be someone among us who has figured out how to get a hard drive formatted within Lion for use with OS 9, right? And truly, if we can figure out how to network Lion & OS9, surely there must be a way to format an external HD with OS 9 drivers and create partitions smaller than 1.07GB in Lion too. Are there few among us who use Lion on their modern Macs?
