I wanted to keep Tiger as my main OS, but fiddle around with Leopard to see what all the fuss is about it. I have a Seagate 320 gb usb 2.0 harddrvie with 150 of space partioned for Tiger. Is it possible that I can install and run Leopard off the ex HD?
Got a tip for us?

First, read this:

Next, try reformatting the USB drive using the above information. Then try to install OS X onto it. Then report back here.

I'm almost positive it's Mac OS X itself that can not be started up from a USB drive, irrelevant of hardware.
Yes it is. And yes, use USB. I extracted the disk image to one partition and then used this to install onto the other partition.
iBooks could only use Firewire to boot; new intels use both.
edit: I just realized that you have already done this, but heres what I did.
I did the same thing your wanting to do.
But I have Leopard running as my main.
I had Leopard installed on my Mac mini's internal drive, I put a little 20GB partition on it and installed Tiger.
I then used Carbon Copy Cloner to clone everything on that partition (which had Tiger on it) to an external USB drive.
Once it cloned it, I then erased the partition on the internal drive, and can now choose between the two OS's on startup by pressing and holding down the option/alt button (just like bootcamp does).
You can download Carbon Copy Cloner off the Internet for free.
Just my two cents in this,

Yes, You can install 10.5 on any USB or Firewire drive, assuming that it is GUID partitioned, and large enough for the OS.
