Presentation, Bundle and Manual
Like the ECS 915P-A sample, the 915-A essentially turned up in OEM fashion with nothing in the box bar the mainboard and the driver CD. Here's the box art.
ECS confirm the bundle to be: I/O Backing plate, Manual, Driver CD, S-ATA Cable, S-ATA Power Adapter, IDE HDD Cable (Ribbon), FDD Cable (Ribbon), exactly the same as the 915P-A. It's a bundle that doesn't inspire, excite or otherwise cause any emotion whatsoever, but which will let you get the board up and running with a minimum of fuss.
The manual, which I've since had a chance to read after the sample went back to ECS, is succinct, well written by an obvious natively English speaker and is easy to search for the information you need.
