Got Tiger? Noticed that there is no Apple Hardware Test CD? No cause for alarm – boot from the install DVD and hold down the D key. Abracadabra! Mac boots into diagnostics – good for checking for faulty RAM.
Another helpful hint from the [coretech](www.coretech.net.au) team.

Or you can hold down the option key to go into boot manager, and then choose the diagnostic DVD-PARTITION from the list.
