How read the HCL?

I am lookng at the Hardware compatibility list for BExec 2012.

1. What does the column mean that says "Library Inquiry/Drive Inquiry"?

2. I dont see the HCL for BExec 2010.  Is Quantum i40 Scalar on it? How about Overland NEO Storageloader.  More details....hmmm.  Hmmmm, maybe better if ya point me in direction of the HCL. Thanks!
