My 4DXi comes with instructions to put the board into 'oops' mode by shorting pins 7 and 8 of the primary (there are two, BTW) serial port at boot-up. One additional note on Ampro boards: I purchased an Ampro 4Dxi from Trilogic a couple of months ago. Trilogic is a nice company in Massachusetts that I learned about from the MIT pages... Anyhow, I had trouble getting it to accept keyboard input, and after getting out the prints from the manual and a VOM, I found that there was no keyboard power from utility connector J5...in fact the pin for keyboard power was missing (pin 8) and the barrel on the board was just filled with solder. HERE IS WHY I AM BORING YOU WITH THIS STORY!!! These boards are mass produced using chip insertion machines and then wave soldered. It is likely that my board wasn't the only one with this fault on that production day. The fabrication version on my board is listed as a CM2-4DI-Q-81 revD. So, if you just bought this great little board and you can't figure out why you can't escape into setup at boot time...check for 5 volts at pin 8 of connector J5! You may not even have a pin 8... The good news is that both Ampro and Trilogic are great companies and they were really quick with their RMA substitute.
