Power cycles on/off 3 times before booting properly from cold start, no other issues (New System)

If ECS suspects that the BIOS is initiating a system reset, then perhaps the system is partway through BIOS code execution. I would recommend inserting a POST code display board into the system to see the last code written to I/O port 80h by the system.

Once you have this, contact ESC (or the BIOS vendor) and give them the last POST code you see on the display. If they have the source to the BIOS (they may not, unless you have a highly specialized embedded PC), they may be able to look up the code in the source and tell you the last thing to happen in the system before the reset condition occurs.

If ECS doesn't have source code to the BIOS, see if you can find the POST code meaning at: http://www.bioscentral.com/.
