I think I fully understand Plug and Play. It is a very desirable
goal to be able to plug in a peripeheral device into a bus slot
and have the system recognize what resources are required and insure
no conflicts exist. True it allows software to be written to
automate this configuration. It is still my contention that a well
designed board will allow the manual overide of these features for
the power user, who has the right reason to make the override.
I would call it Power user Overide. I've been writing software
and designing hardware too many years to assume that I can do
everything after the hardware is powered up. So as long as other
design considerations allow it I will always choose the board that
will allow manual setting of at least intial resource allocations.
I fully prefer those that allow me to do power on configuration, either
automatic or semi as long as they also give me manual options as well.
I believe that the better products will have both features
and and are well worth the additional cost. My time is way too
valuable to try to save the last penny on hardware outlay. I also
prefer those products that provide excellent documentation, prefererably
machine readable. Right now Plug N Play still seems to be a selling
feature that is substituted for poor documentation in some off brand
boards. In my recent upgrades I ran into poor PnP and good PnP
implementations. The good implementations were not afraid to give me
manual options as well. Be careful in sellecting Plug N Play products,
Especially if you want to mix it with non-plug and play boards on
platforms that use more than one OS. My recomendation to a hardware
designer who is developing a new product is still please provide some
manual control to give the power user some flexability to over come
unforseen requirements.
PCMCIA is one place where the manual overrides is probably
one place where the manual override in impractical.
By the way there are users that I fully recomend plug and
play to. I made the assumption that the Hardware person who asked
about pitfalls was truely interested in why some of us had found
problems with PnP. I did not say that I had abandoned PnP, only
that I was selective in which PnP devices I bought.
