Probably the best general overview of Mach is now the Chapter in
Sliberschatz and Peters Operating Systems Concept book that Richward
Ward refered to a couple of posts ago. In genreral, if one is talking
about Mach 2.5 and there is not a specific Mach way of doing something, e.g I/O,
then use the Unix (4.3 BSD) way. All the Unix kernel interface is
supported so that Mach didn't have to rewrite something that was not
central to its design. If you are talking about Mach 3.0 then it depends
on what sort of servers you have running and what functions they support. 
At the moment most Mach 3.0 servers are still in the implementation or
early testing phase.
