NetPort & NetPort II: Compatibility with DOS 5.0
DOS 5.0 AND NETPORT
We have tested NetPort with workstations running DOS 5.0, and did not find
any compatibility problems. DOS 5.0 offers the user a level of memory
management beyond that of any previous version of DOS. For that reason,
users may have concerns about the functionality of software utilities when
upgrading to DOS 5.0.
In general, NetPort utilities are not resident, that is they do not remain
in memory after you have "run" them. For that reason, the use of DOS 5.0
Upper Memory Blocks (UMBs) does not make sense with such NetPort software
as NPCON, NPLIST, NPQUERY, etc.
The significant exceptions to this are NPREDIR and NPMON. These are both
TSR (Terminate and Stay Resident) utilities.
NPREDIR stays resident in the DOS workstation in order to "capture"
output to the printer port and redirect it to the NetPort via the
network. NPREDIR requires approximately 14k of memory for the first
NPMAP connection, and another 4k for each additional NPMAP
connection.
NPMON allows designated operators to their assigned NetPort servers,
and uses approximately 20k of memory.
Either of these can be successfully loaded into UMB memory, thereby saving
conventional memory on the workstation. In order to configure your system
to load NPREDIR or NPMON into UMB memory, refer to your DOS 5.0 manual,
the manual for your 80386-control program (QEMM386, 386MAX, etc), or the
manual for your UMB utility program (QRAM, MOVE'M, etc).
If you are using DOS to manage UMBS via the DOS=UMB line in your
CONFIG.SYS file, you would simply prefix your NPMON or NPREDIR command
with LOADHIGH or LH. If there is a sufficently large UMB area available,
DOS will load the utility into that UMB area. Otherwise, the utility will
be loaded into conventional memory.
For more information on Upper Memory Blocks (UMBs) in general, please
refer to FaxBACK doc number 1158.
If you are experiencing problems with your NetPort utilities after
upgrading to DOS 5.0, please verify that you are not experiencing network
problems in general. DOS 5.0 may require that you update some of your
Novell files. Refer to the NETWORKS.TXT provided with DOS 5.0.
