THE SDCONECT PROGRAM

The SDCONECT program controls the IFS.  With SDCONECT, you 
attach and detach the virtual drive and get the status of the IFS.


You use SDCONECT:

     o  During system initialization time to establish the CD-ROM and virtual
        drive letters.

     o  Any time to change the virtual drive letter.

SDCONECT communicates with the IFS to tell it the location of the locked
files and the letter of the virtual drive.   It may run in your CONFIG.SYS file to 
automatically establish the connection to the IFS at system boot up time.

The syntax of SDCONECT if used from a command line is:

      SDCONECT srcdrv: [virtdrv:] [/Q]

      Specify source drive and attach virtual drive.  If virtdrv: is not
      specified, the first free drive found is used.  If /Q is specified,
      no informational messages are displayed.

      SDCONECT [virtdrv:] /cd[:N]

      Attach the first available CD-ROM drive to virtdrv:.  If virtdrv: is not
      specified, the first free drive is used.  You can optionally specify
      which CD drive to attach to virtdrv:  For example, if you want the third
      CD drive on your system attached to the Z: drive, specify: SDCONECT Z:
      /CD:3.

      SDCONECT [virtdrv:] /D

      Detach virtdrv: or currently attached drive.

      SDCONECT

      SDCONECT considers the drive it's executed from as the source drive, and
      it uses the existing virtual drive or the next available drive letter.

      SDCONECT /S

      Display the current status for the SDCS control program.

      SDCONECT /V [/Q]

      Display the drive letter of the current virtual drive and set the return
      code to match.

             No virtual drive = 0
             A:=1, B:=2, ..., Z:=26
             Anything else is an errorcode

The /Q flag tells SDCONECT to output only the failure messages.  For example,
if the /Q flag is not used, the screen output looks like the following:

         Drive I: is now connected to H:

(This example assumes that H: is the CD-ROM drive, I: is a free drive, and
you invoke the program as: SDCONECT /CD)

The /V flag is provided for use of SDCONECT in a CMD file.  SDCONECT
returns a numerical value equal to the virtual drive letter in use (A=1,
B=2,...,I=9).  If no virtual drive is connected, the return code = 0.  Any
other return code is an error code.

UPDATES TO YOUR CONFIG.SYS

The following lines must be added to your CONFIG.SYS 
during setup, or you can manually add them:

             IFS=C:\OS2\BOOT\SDCFS.IFS
             RUN=C:\SDCTL.EXE

NOTE:  You must shut down your system and reboot for the changes to take
       effect.
