      BACKGROUND
      
      QEMM version 7.0x includes a device driver called DOSDATA.SYS. If
      you have QEMM versions prior to 7.03, you may find that your
      computer "hangs" at that line during startup.
      
      SOLUTION
      
         - Modify your CONFIG.SYS to permit the startup process to
           proceed.
         - Upgrade to QEMM version 7.03.
           
      Modify your CONFIG.SYS to permit the startup process to proceed
      
      When starting your computer with QEMM installed, you may press
      the ALT key to boot without installing DOSDATA.SYS. This will
      allow you to modify your CONFIG.SYS file.
      
       1.  Restart your computer. After the machine "beeps", press and
           hold the ALT key. When you receive the on-screen message to
           press <ESC> to unload DOSDATA, release the ALT key and press
           ESC.
       2.  At the DOS prompt type ED /C <enter>.
       3.  Add the following switches to the end of the DOSDATA device
           line: /B:2001 /IODATA-. the line should now look like this:
           DEVICE=C:\QEMM\DOSDATA.SYS /B:2001 /IODATA-
       4.  Save the file and restart your computer.
           
      Upgrade to QEMM version 7.03
      
      Contact Quarterdeck to upgrade to version 7.03 of QEMM. You may
      then remove the switches from the DOSDATA.SYS line.
