-
- We have tested the LANtastic starter package with DESQview
- versions 2.2, 2.3 and QEMM-386 versions 4.2-5.1. The LAN starter
- kit consists of two 2 Mbps LAN adapters, cable, & terminators and a
- system disk with version 3.02 of LANtastic NOS.
-
- 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-386 or other memory manager, you must exclude the LAN
- adapter ROM address space, D800-DFFF. See page 196 of the
- LANtastic NOS user guide for more information.
-
- The new 10MB Ethernet adapters do not use any ROM or RAM
- addresses so no exclusions are necessary.
-
- LANBIOS.EXE is the program that activates the network
- adapter in your PC. It uses 2K and can be loaded high.
-
- REDIR.EXE is the networking software. Each PC node on the
- network must run this. 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 in addition to
- being a workstation. It takes about 30-50 K and in most
- cases can also be loaded high.
-
- LANtastic uses DOS's SHARE.EXE to provide basic file protection and
- locking. Non-network versions of software can be run by only one
- user at a time. Some users have suggested:
-
- SHARE /F:4096 /L:200
- in AUTOEXEC.BAT.
-
-
- RUNNING DESQview on LANtastic NOS
-
- DESQview should be run from a local disk or from a unique
- directory on the server. Initial installation of DV will take 350-
- 400K of disk space.
-
- You may want to try using the DESQview parameter, /DT (DOS
- Terminate). This tells DESQview to pass any calls to terminate a
- program directly to DOS, instead of having DESQview itself
- perform the termination. Some DOS utilities (such as SHARE.EXE) and
- networks may not be able to keep track of programs if DOS doesn't
- see terminations.
-
- The network drivers (LANBIOS.EXE, REDIR.EXE) should be run before
- invoking DESQview. Loading them in a DV window is difficult at
- best, and will severely degrade the performance of the network.
-
- NET and Lanpup can be run in DESQview to access network features
- like Mail and Chat. If you use Lanpup, you should run it in
- Stand Alone mode (/S) inside of DESQview, not before it or else
- multitasking will stop while LANPUP messages remain on the
- screen.
-
- NET uses around 20K and LANPUP uses about 5K and both write
- directly to the screen. The "Writes directly to screen" option
- should be set to Y for these programs to prevent bleed through.
-
-
- DESQview on a LANtastic Server
-
- In order to use DV and LANtastic together you may save yourself
- some work by not installing the server option of LANtastic.
- There is a conflict that MAY or MAY NOT show itself if the SERVER
- program has been loaded.
-
- Even though the servers in LANtastic are not dedicated, DESQview
- should not be run on a PC designated as a server with LANtastic
- NOS versions 3.02 and earlier. Programs run in DESQview are
- allowed to access DOS but the LANtastic Server wants exclusive
- access to DOS at certian times and will attempt to prevent access
- to DOS. It is this condition that may cause problems.
-
- Symptoms include computer lock-up, access denied, or computer re-
- boots. It most readily shows up when running 2 or more
- applications under DV that access data/programs across the net.
- (Working locally seems to work ok.)
-
- If you must be set up as a SERVER, and are experiencing these
- problems you can work around this by setting the SHARE CPU WHEN
- IN FOREGROUND to N and RUNS IN BACKGROUND to N in Change Program
- for applications that access DOS in a manner that causes crashes.
-
- For more information about Changing a Program's information,
- please see chapter 7 of the DV Manual and the grey DV upgrade
- pamplet.
-
- This will allow you to switch between programs, but will not run
- these programs in background.
-
- Another option is to setup your LANtastic Network with a PC
- dedicated as a server and only run DV on a non-server.
-
- Quarterdeck is currently investigating to see if a modified
- version of server.exe will be able to tell DV not to multi-task
- during critical operations performed by the server.
