Artisoft Technical Bulletin Updated: 04.11.94 Running LANtastic v5.0 or v6.0 in an OS/2 Virtual DOS Machine Engineers: AEJ/MWF 컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴 Your computers running OS/2 can use LANtastic features by running the network software in an OS/2 Virtual DOS Machine (VDM, or VMB). Note Before you begin, make sure you have the latest version of the FSFILTER.SYS file. LANtastic will not run using the version included in most OS/2 packages. The correct version of this file is available on the Arti-Facts bulletin board. See the LANtastic User's Manual for information on downloading files from the Arti- Facts BBS. 1. On a computer running DOS, or in a DOS window on an OS/2 computer, prepare a bootable floppy diskette. It's recommended that you use a 1.2 MB or 1.44 floppy diskette. To create a bootable floppy disk, type FORMAT A: /S * at the DOS prompt, where "A:" represents the drive containing the diskette you want to create. 2. Using a text editor, create a CONFIG.SYS on the bootable floppy diskette. It should contain these commands: DEVICE=FSFILTER.SYS FILES=50 BUFFERS=32 LASTDRIVE=Z FCBS=16,8 You may also include any other commands that you want executed from the CONFIG.SYS. 3. Create an AUTOEXEC.BAT for the bootable floppy. It should contain these commands: @ECHO OFF PROMPT $P$G PATH=C:\;A:\;C:\LANTASTI; C: CALL C:\LANTASTI\STARTNET.BAT As with the CONFIG.SYS, you may also include any other commands that you want executed. 4. At the OS/2 machine, open a DOS window. Choose the OS/2 System icon, choose Command Prompts, then choose the DOS Window icon. 5. In the DOS window, change to the directory C:\OS2\MDOS. 6. Download the file FSFILTER.SYS from the Arti-Facts bulletin board, as instructed in your LANtastic User's Manual. LANtastic will not run using the older version of FSFILTER.SYS included in most OS/2 packages. Copy the new FSFILTER.SYS to the bootable floppy diskette. * Native OS/2 DOS does not support FORMAT /S. WARNING! Do not attempt to run LANtastic without obtaining and loading FSFILTER.S YS. 7. Create a virtual DOS image file on the OS/2 computer. To do this, enter the following at the prompt: VMDISK A: C:\OS2\MDOS\LANTASTI.IMG where A: is the drive containing the bootable floppy diskette. 8. Place the LANtastic installation diskette in a floppy drive. At the DOS prompt, type A:INSTALL . Run the LANtastic installation program as directed in Chapter 2. When the installation is complete, follow the bulleted steps below if you want the OS/2 computer to share resources with other nodes on the LANtastic network.  At the C:> prompt in the DOS window, type NET_MGR .  Choose Shared Resources Management.  Choose a drive that you want to share.  Select Disk Drive Type, then choose OS/2.  Repeat steps 3 - 4 for each drive you want to share. Press Esc at each screen to return to the NET_MGR main menu.  Choose Server Startup Parameters. Enter the requested path information . From the Server Startup Parameters screen, choose NON-DOS Disk Support and type 100 . Press Esc at each screen to return to the DOS prompt. Note: Don't forget to change Disk Drive Type for the " . => C:\LANTASTI.NET" resource to OS/2, or you won't be able to see any directory listings. 9. Close the DOS window by double-clicking in the upper left corner of the window. 10. Click the right mouse button on DOS FULL SCREEN to bring up a menu. Choose Copy to create a new object for the virtual DOS machine. Note: You can click on a DOS window, but DOS FULL SCREEN will allow you to run WIN.EXE (from OS/2 for Windows) or WINOS2.EXE (from regular OS/2) from within the VMB. 11. Click on the New Name box and enter a name for the object. For example you might type LANtastic VDM . 12. Click the left mouse button on the new object, then click the right mouse button to bring up the object menu. Click the arrow next to the Open menu option to bring up the Settings menu, then choose Settings. 13. Click on Session to bring up Session parameters, then click on DOS Settings. 14. Click on DOS_STARTUP_DRIVE. Click on the Value box and type in the drive and path as created in step 7 (C:\OS2\MDOS\LANTASTI.IMG). Click on Save. 15. To allow printing, or if you're running Central Station from OS/2, you must:  From the OS/2 Desktop, click on OS/2 System, then click on System Setup.  Click once with left button to select Spooler, then click once with right button to open a menu.  Select Disable Spooler to allow direct access to the printer port. 16. Restart the virtual DOS machine by double clicking on the new object (LANtastic VDM in the example above) and the network will load. The OS/2 machine will now function as a LANtastic server and/or workstation. Special Considerations for OS/2 Workstations and Servers  The network adapter card must be in 8-bit mode. If you have Service Pak XR06055, available from IBM, you may be able to run in 16-bit mode.  You cannot NET USE drives on your local computer from the virtual DOS machine. You can (and should) NET USE your local printers if your machine is configured as a Server.  If you're using OS/2 V2.1, you must install the LANtastic server using the SERVER/NO_5D switch. If you're using a STARTNET.BAT file to run the network, place this switch on the SERVER line. For example SERVER/NO_5D .  Don't run the DOS SHARE program in the virtual DOS machine. Because SHARE does not function correctly in the VDM, please be aware that sharing a database from the OS/2 VDM is not supported since record locking will not function and data corruption may occur if multiple users access the same database. File locking IS functional.  Disk writes to OS/2 show problems with workstations under NetWare DOS. Don't install LANtastic on workstations running NetWare DOS if you're connecting to an OS/2 server.  VMDISK returns a CRC error when a floppy disk is formatted with MS-DOS 6.2. ServicePak XR06200 is required to use MS- DOS 6.2. ARTISOFT, Inc. makes no warranties as to the completeness or accuracy of this document. LANtastic is a registered trademark of ARTISOFT, Inc.
