I need Tiger to run my design software and Leopard came on my new Mac Pro. How do I get both on my machine to boot from one or the other? Or is it possible to run both side by side as with Widows.
I read the thread for Panther and Tiger and wondered if Tiger and Leopard would be different.
Thanks for your help!

It seems like the same process would work, If it doesn't you could try virtualization software (I've never used virtualization with a mac client, but I'm sure it exists) to tun tiger for your design work.

I'm surprised that any Tiger software wouldn't work on Leopard, have you actually tried installing it?
