We have tested the starter package with DESQview versions 2.25
and 2.26, The LAN starter kit consists of (2) 2mbps lan adapters
and a system disk.
Installation was rather easy, and the instructions in the manual
are complete. If you are installing this system on a 386 and are
using QEMM 4.23, you must exclude the lan adapter rom address
space. These are documented in the Lan Adapter user manual on
Pg. 6 (table 2). Default is D800-DFFF.
LANBIOS.EXE is the program that activates the network
adapter in your PC. It uses 1K and can be loaded high.
REDIR.EXE is the networking software. Each PC has to run
this to be on the network. It uses 11K and can be loaded
high.
SERVER.EXE is an additional program that enables the PC
running it to be accessed as a file server rather than just
as a workstation. It takes about 22K and in most cases can
also be loaded high.
Lantastic uses DOS SHARE.EXE to provide basic file protection and
locking. Non-network versions of software can be run by only one
user at a time.
We find that with DESQview 2.25, you may want to try using an
undocumented parameter, /DT. This tells DESQview to inform DOS
when DESQview closes files. Generally, DESQview is able to run
many programs without using DOS, and for the sake of speed we
don't tell DOS when we close files. Network software that
requires running SHARE.EXE may need /DT to keep things straight.
This may help if you are experiencing lock-ups running DESQview
on a Lantastic server.
I have been able to run DESQview 2.26 from the workstation as
well as from the server. But as a rule, each workstation
should run DESQview locally or run it from a unique directory on
the server.
Since the servers in Lantastic are not dedicated, DESQview can
be run on a pc designated as a server. If you do this, you must
login to the server like the workstations do, to minimize
degradation of performance of the network as a whole.
There are also two other programs, net and net_mgr, which can be
run on a dos command line or as a network menu program if no
parameters are given to them. This is the only part of Lantastic
that could be run in a DESQview window, but is not recommended as
it may cause lockups.
The network drivers (lanbios.exe, redir.exe and server.exe) MUST
be run before invoking DESQview.
Also it has been noted that when running DESQview on the server and
using the Lantastic print spooler, DESQview's "Manage Printer
Contention" option should be set to [N].
