[Macpartners] OSX 10.4 iso disks

[Jonathan McIndoe Hunt]

Hi Felix,

The trick is use Disk Utlity on a Macintosh to burn the ISO images to 
CD and use that to install Mac OS X 10.4.  What application did you 
use to burn the ISO image to CD?  I have validated that the CD-R 
created using Nero on a PC fails as you have experienced.

Tiger cannot be installed from a virtual disk on pre-Tiger systems 
because of the underlying file system changes necessitate have the 
booted OS being Tiger which is why you couldn't install from teh 
mounted disk images.  The ISO images are for CDs, so burning all four 
to a DVD won't yield a useful disk as you discovered.

We will track down the issue with the image not being bootable when 
burnt from some applications.  By using the ISO format, the CD-R 
created from the image should be indentical and independent of the 
burning tool or platform on which they were burned, but alas you're 
finds as well as our latest test show that not to be the case.

A brief definition of ISO images can be found at 
http://en.wikipedia.org/wiki/ISO_image.

Thanks,
Jon
