This is all a bit crazy.  Is the LSI series of HBAs really the only choice
outside of onboard controllers?  It seems like they are troublesome, support
is spotty, and this whole flashing process gives me nightmares.

Also personally, with the few boards I’ve seen with built-in LSI adapters
have always been a little wonky compared to their non-LSI counterparts.

Is this all just the end-result of LSI basically buying up everyone?
