Ok, I can see how this works. If I load the overlay for 'quick test', then manually go into diagnostics and load the 10 or so different pages, I can see what is included in the quick test. If I use this procedure for each of the pre-done overlays, I could figure out what is a subset of what, and build an custom overlay that includes what I want.
Is this printed out in the manual anywhere to help me with this process? I'd like to avoid manually paging through and recording each screen to accomplish the goal (issue one command, have it run all the procedures I want then tell me the answers all without user intervention).
Is there any way to concatenate the tests available on the main screen? In other words, somehow enter 1,4,5,M and hit "Go" to run the Quick Test overlay, followed by the CPU test overlay, followed by the Motherboard test overlay, followed by the Maximum System Load test -- all without user intervention? I realize there would be some overlap, but this would accomplish the goal.
