Hi...
Got two questions, really, first is more general:
I have a semi-newbie question. What exactly is tagged command queueing?
Does it mean I can send commands for different drives to the controller and
it will queue them or does that mean the device itself handles the requests?
Lets suppose I have 1 drive that allows queuing and another that doesn't.
Does that mean anytime I send something to the non-queueing drive I have
to wait on that drive before sending any other commands over the bus? Or
is the driver re-entrant such that one thread could be servicing the NQ
device while other threads would be putting queued commands on the bus
for other queueing devices?
2nd -- where do I find the Hardware Programmers Guide for the adaptec
series -- specifically the 7890 -- like what language is downloaded into the
drive, hardware states, etc? I can't seem to find the right location on
the adaptec website.
Thanks!
