Restoring Registry

To restore registry, do the following:

• End the RSRV session by:

  a.

  Editing CONFIG.SYS and removing the following line:

  RUN=...\RSRV.EXE
  

  Note: This line will be added back later.

  b.
  Restarting the system.
  2.
  Delete all *.DAT files in the root directory of the boot drive: BOOT.DAT DOS.DAT REGISTRY.DAT
  
  • Add the following line back in the CONFIG.SYS file:

    RUN=...\RSRV.EXE
    

  • Start up an RSRV session by going to the OS2 directory and typing:

    start rsrv
    

  • Go to the OS2 directory and type:

    inst_dos dos
    

  • Then, type:

    reginit
    

  Now registry is fully restored to post-system installation level.

  If you want to save your registry data, archive DOS.DAT on the root of your boot drive. In case of corruption, to restore data to this level, do the following:

  • End the RSRV session by:

    a.

    Editing CONFIG.SYS and remove the following line:

    RUN=...\RSRV.EXE

    Note: This line will be added back later.

    b.
    Restarting the system.
    2.
    Delete all *.DAT files in the root directory of the boot drive:

    BOOT.DAT DOS.DAT REGISTRY.DAT

    3.
    Add the following line back in the CONFIG.SYS file:

    RUN=...\RSRV.EXE
    

    4.
    Copy the archived file as DOS.DAT in the root directory.
    5.
    Go to the OS2 directory and type:

    inst_dos dos
    

    6.
    Start up an RSRV session by going to the OS2 directory and typing:

    start rsrv
