This subdirectory contains the driver for Adaptec's AIC-7800 Family of Host 
Adapters for NetWare 386 v4.xx SCSI and Advanced SCSI Programming Interface
(ASPI) managers. All of Adaptec's NetWare 386 drivers have full support for
standard SCSI disk drives, "NetWare Ready" drives, and removable media disk
drives (including optical drives).

The driver also contains a built-in ASPI manager.  This allows for other
NetWare Loadable Modules (NLMs) to gain access to the host adapter.
Given the flexibility of ASPI, several companies are currently providing
server-based tape backup solutions through ASPI.  SBackup is a server based
tape backup solution which is shipped by Novell with NetWare 3.11.  SBackup
supports the ASPI interface.  There are other ASPI modules already developed
or under development.  A programming specification is available from Adaptec
if you are interested in writing your own NetWare 386 ASPI module.

If your file server does a lot of IO operations and you want to try opti-
mizing its performance, you can adjust the "max_tags=?" and "max_notags"
command line switch.  For example:

:load aic7870 max_tags=2 max_nontags=1
           or
:load aic7870 tag_disable=ffff max_nontags=1

The first example is set for tag-queuing drives and the second case is for 
non-tag-queuing drives. The max_tags parameter can be set as 2, 4, 6, 8, or
10.  The max_non_tags parameter can be set as 1 or 2.
