A1181: How to run ASD or AHT on this macbook? I have Lion installed on this 2007 macbook. OS was installed from A1384 USB drive.

How do I run AHT (or ASD) on this macbook? I tried hitting / holding "D" during normal bootup and it will start normally. When inserting the stick it will run into Install screen with no options or menus for AHT/ASD.

Is there a source for a CD/DVD to burn with those tools?
The only official source, if you have lost your original OS X DVDs is to purchase one from the Apple Store

Later models have the Hardware Tests built into ROM, earlier ones must use those on the DVD.

If you've got a [physical] Apple Store near you, they're usually quite obliging for that kind of thing.
