The Series 700's use EISA for expansion as of the HP-UX 8.05 release.  The
first machines are running 8.01.  8.05 will be the release shipped to all
but the very first customers.  Approximately mid July, 1991 a version of
the HP-UX Driver Development Guide for 8.05 will be released.  This will
include information for developing EISA kernel drivers on the Series 700.
This release will also include information for develping VME, DIO, and EISA
drivers on the HP-UX 8.0 release for our Series 300/400 SPUs.

A version of the HP-UX Driver Development Guide for 7.05 (VME, DIO, and EISA
on the Series 300/400 SPUs) is currently available.  The part number for
this guide is 98577-90012.

Note that drivers' developed for EISA on the Series 400 are source code
compatible (assuming they follow conventions and calls as outlined in the 
Driver Development Guide) with EISA on the Series 700.

HP-UX kernel driver semantics are BSD based with the addition of some HP
specific services related to an interface select code (isc) structure upon 
which services such as select code and device queueing are based.  In 
addition, the HP-UX kernel auto configures based on code using the isc
structure and services.


Usual babble about ideas comments, etc being mine and not my company's ...
