is there a difference if im trying to burn a bootable dvd?

Just go to Disc Utility and press burn.

By any chance, is this for Tiger?

I can't get mine to work. It keeps kernel panic-ing at setup. It might be a bad DVD so I might try burning it again.

If it's supposed to be bootable, and burning it using Toast (or Disk Utility) doesn't work, try this: lock the disk image first (do a Get Info on the file, check "Locked" ), then use Disk Utility to burn it to a blank CD or DVD. Make sure you don't double-click on the disk image file (therefore causing it to mount) before you burn it.

As for the Tiger developer preview installer crashing, it's a very early beta build so no surprise there. :-)

from a certain forum

"Penguiner, gorman, Mullet, matrix918, and I were hacking around with the Preview last night and early into the morning to see what was up with the kernel panics people have been getting. It seems that that bootloader (or something that happens right after) is checking for certain models of machines, but the 'wrong' model is returned by the Open Firmware (even though it's the correct number for your computer, it doesn't match what the disc is looking for) and thus it panics.

Here's a really slick way around this problem that penguiner came up with:

1. Start off with a machine that has two partitions.

2. Have the Preview dmg on the partition you're booted from, and format the other partition to Mac OS Extended (aka HFS+) with Journalling turned ON. It seems the Preview won't install without journalling, for now.

3. Mount the Preview dmg, and the Install Mac OS X window will open. Close it and re-open the root of the mounted disc. Note that the ' Install Mac OS X' folder is inside the root and is not the root of the disc/dmg itself.

4. Inside the root of the dmg is all the system information needed to boot off the DVD. Including....the OS installation software!

5. Open the System folder, Installation, Packages and double-click OSInstall.mpkg ( /System/Installation/Packages/OSInstall.mpkg ). That is the OS installer for the Preview.

6. When it runs, pick the blank, journalled partition of your drive and install. Everything is installed with this mpkg. Then pick it in the startup disk pref pane.

Neither I nor penguiner make any guarantee about this. It's totally the wrong way to go about installing an OS. But a hack's a hack. Nice work, guys. Your mileage may vary.

I had a theory based upon this to use a single partition drive...If you made a 10.2 or 10.3 bootable CD with BootCD (google it) and had the dmg file on a FireWire drive, you could do the same process as above, but booted off a CD and installing off the FireWire drive ONTO the internal drive of an 'unsupported' machine. I have not tried this yet, but will soon...I need to back up my PowerBook5,2 ;-P "

If you're trying to install Tiger DP using the hack you posted above, just focus on the following steps:

1. Start off with a machine that has two partitions.

2. Have the Preview dmg on the partition you're booted from, and format the other partition to Mac OS Extended (aka HFS+) with Journalling turned ON. It seems the Preview won't install without journalling, for now.

Your Mac's hard drive needs to have two partitions at the least for the hack to work. Place the .dmg on your current system partition/startup disk (the one you're booting from right now) and make sure the other partition is formatted as HFS+ with Journalling enabled. The assumption is you're currently running your Mac from the main partition (where the .dmg should be).

3. Mount the Preview dmg, and the Install Mac OS X window will open. Close it and re-open the root of the mounted disc.

Do the above. "Re-open the root of the mounted disc" is just a fancy way of saying double-click on the disk to see its contents, hehe.

4. Inside the root of the dmg is all the system information needed to boot off the DVD. Including....the OS installation software!

5. Open the System folder, Installation, Packages and double-click OSInstall.mpkg ( /System/Installation/Packages/OSInstall.mpkg ). That is the OS installer for the Preview.

Look for the OSInstall.mpkg file at the above location and run it to install Tiger DP. Choose the other partition as the installation location. Once the installation's done, change the System Preferences -> Startup Disk setting to boot from your newly-installed Tiger DP system. ;-)

The beauty of the hack is that it doesn't require you to boot from a Tiger DP CD/DVD. I'd only install Tiger DP for demo purposes though. Early build = buggy = not ready for primetime. :-)
