	Well, I don't believe either of these are actually DIRECTLY supported
by AIXv3.1.  Check with your salescritter for further clarification on that,
though.

	Well, there's nothing per-say broken with the drivers in 
/usr/lpp/bos/samples, they're just not complete.  The headers say something to
the effect of "this is only a partial driver".  Basically caveat hactor...:-)
As for information on writing drivers for the 6000, InfoExplorer has books on
supplied Kernel Extensions, which talks about device driver operations and 
Kernel Extensions and Device Support Programming Concepts, which has a chapter 
on writing a device driver for AIXv3,

	There is also an article in the first (I believe) edition of AIXpert
magazine (an IBM publication about the RISC System/6000 -- see your sales rep.
to get a subscription) which has an article on the how/where/when/why/what of
writing an AIXv3 device driver written by Sam Drake from IBM's Almaden Research
Center.

	Hope those help.

These opinions are my own.  I doubt IBM wants them.......
