It's relatively important to know that only the DOS-version, and only 
P14 (and below, probably) allows cross-flashing HBAs).

The tutorials don't really say that, they kind-of assume that you will 
use the DOS-binaries anyway.

In my IT-career, I've really only touched DOS a very small amount of 
time. Imagine my aversion at creating a DOS boot-disk ;-)
