This is a Toast image file for the Leopard Installation Disc. It works best with Toast:
Open Toast,
Select Copy,
Select "Image File",
Select the image file--->osx-leopard105.toast,
Insert a DVD-DL,
Burn the disc in the following name:
Mac OS X Install DVD.

Once it is done, ENJOY LEOPARD!

NOTE: I have tried this. It installs very well, and has installed on five different machines: Macbook (4), and iMac Aluminum 20". The install may "Freeze" the first time, but second time is a charm :)


Cheers Boys!
