i want to run Apple Hardware Test but lost my original installation disk... i have a 13" 2 GHz Intel Macbook that was purchased in late 2006 and my build is 10b504. im currently running Snow Leopard on it... does anyone know where i could find a .dmg file of this or something?

some information i have learned thus far:

Apple site has some AHT downloads available, but the only ones i could find are computer specific for pre-2000 or early 2000s

AND retail Snow Leopard does not come with AHT... i need the computer specific version of AHT that fits with my 2006 13" Macbook
