Heh, the hardware is cake man, don't sweat it, the scsi stuff is just knowing how long the cables are, it doesnt ask you bus widths or anything like that, the OS technologies, you should study for, make sure you know the boot processes, for both 9x and 2k, and what each step does. Also know the diagnostic tools for both (such as drwatson for 9x, etc etc.) The pringer questions are easy, the hardest kind are the laser jets because they are more complex than bubble or reg ink jets, just learn the steps in order, and what each step does, that way you can use logic on their questions.
