- PC SUPPORT/400 UNDER OS/2 2.0 INFORMATION
- -----------------------------------------
-
- Description: This FAX describes how to install and use IBM PC Support for DOS
- under OS/2.
-
-
- In DOS PC Support/400, the Shared Folders device driver is a block device
- driver. Since the virtual DOS machine of OS/2 V2.0 does not support block
- device drivers, DOS PC Support/400 must be run in a Virtual Machine Boot
- session. We will describe below the setup of DOS PC Support/400 in a DOS
- 5.0 Virtual Machine Boot(VMB). The process creates a DOS 5.0 boot diskette,
- which is then copied as a diskette image to the hard disk. This enables
- the DOS PC Support/400 Virtual Machine Boot to be started from the hard
- disk rather than a diskette.
-
-
-
-
-
- STEP 1: INSTALLATION PREPARATION:
- ----------------------------------
-
- The following are required before starting the installation:
-
- 1. Basic DOS PC Support/400 Installation diskette(s) V2R1 or later
- 2. DOS 5.0 bootable diskette, formatted with the system (/S) option
- 3. If using a LAN, the LAN Support Program diskette 1.22 or later
- 4. DOS PC Support/400 Installation and Administration Guide (SC41-0006).
-
-
-
- STEP 2: INSTALLATION CONSIDERATIONS:
- -------------------------------------
-
- If DOS PC Support/400 is to be used on a LAN, you must first install the LAN
- device drivers on the DOS 5.0 diskette with the LAN Support Program
- diskette. This puts the DXMx0MOD.SYS drivers in the CONFIG.SYS of the DOS
- 5.0 diskette which can be used with your VMB.
-
- 1. Run the DOS PC Support/400 installation program.
-
- a. During the installation, you will be asked which "Drive your
- personal computer starts from?". This must be answered as the
- A: drive.
-
- b. When you are asked to "Insert diskette from which you will start
- the personal computer in drive A.", insert the DOS 5.0 boot diskette.
-
- Further instructions on how to use the Install program are in the
- guide.
-
- 2. When the DOS PC Support/400 installation program has stopped, add the
- following line to the top of the CONFIG.SYS file on the DOS 5.0
- diskette:
-
- DEVICE=X:\OS2\MDOS\FSFILTER.SYS (where X: is the drive where OS/2
- is installed)
-
-
- NOTE: FSFILTER.SYS is a special DOS device driver that allows a Virtual
- Machine Boot session to access (read/write) all OS/2 V2.0 drives (both
- FAT and HPFS). Without this driver, the Virtual Machine Boot session
- can only READ from OS/2 V2.0 FAT drives.
-
- 3. Create a Virtual Machine Boot diskette image file from your DOS 5.0
- diskette with the following steps:
-
- * Put your DOS 5.0 diskette in drive A:
- * At a OS/2 or DOS command prompt, enter:
-
- VMDISK A: C:\PCSDOS50.DSK
-
- This will create a file that contains an image of the DOS 5.0
- diskette.
-
- 4. Create a new VDM object on the Workplace Shell desktop.
-
- * Locate and open the Templates folder.
- * Locate the Program object template.
- * Using the right mouse button drag a Program object template
- to the desktop. The Program NOTEBOOK metaphor will apear.
- * Enter an asterisk "*" in the Path and file name field.
- * Select the Session NOTEBOOK tab.
- * Select either DOS full screen or DOS window and then select the
- DOS Settings... pushbutton.
- * Select the DOS_STARTUP_DRIVE list item and then enter:
-
- C:\PCSDOS50.DSK
-
- in the upper right entry field.
-
- * Select the Save button to save the DOS settings and return.
- * Select the General notebook tab.
- * Change the Title field to DOS PC Support/400 or your own name
- describing the new object.
-
- * Close the Settings notebook by double clicking on the system menu
- in the upper left corner of the window.
-
- Now there will be a DOS PC Support/400 object on your desktop. Double click
- on it to start DOS PC Support/400.
-
-
-
- PCSUPPORT RESTRICTIONS:
-
- The following general restrictions apply to this environment:
-
- * Only the Basic DOS (Not Extended DOS) version of PC Support/400 is
- supported.
-
- * Only Version 2R1 or greater is supported.
-
- * Only a single DOS PC Support/400 virtual DOS machine(VDM) is supported.
-
- * If OS/2 Version 2.0 Extended Services is used, the OS/2 version of PC
- Support must be run instead of the Basic DOS version, as the device
- drivers used by DOS PC Support/400 requires exclusive control of any
- adapter used for DOS communications.
-
- * When a Virtual Machine Boot session is started from a diskette image
- file, the A: drive within the VDM will refer to the diskette image
- file. If you would like to access the physical drive A: OS/2 V2.0
- supplies a program called FSACCESS.EXE to do this. See the online
- command reference for usage instructions.
-
- * The default hot-key of Alt-ESC is reserved for OS/2 V2.0 and must be
- changed in order to have hot-key support. This can be done by using
- the Configure WorkStation Function (CFGWSF.EXE) program to create or
- change a keyboard profile.
-
- * For LAN connections, only the LAN Support Program Version 1.22 or
- later is supported.
-
- * If you decide to close the DOS PC Support/400 Virtual Machine Boot
- session while the LAN router is active, you must wait two minutes
- before starting up the VDM again. This time will allow the card to
- reset itself on the LAN. The DOS PC Support/400 VDM will appear to
- hang if it is restarted too soon.
-
- * For an SDLC router, if you decide to close the Virtual Machine Boot
- session while the router is active, you must stop the router or power
- off the modem first. Failing to do so could cause a system trap to
- occur.
-
- * The ASYNC router is NOT supported at this time.
