      STACKER NOTE                                         STACKER NOTE
       SETUP ON SHARP 6700 & 6800 NOTEBOOKS & OTHER SYSTEMS WHERE BIOS
                  DOES NOT SUPPORT CERTAIN INTERRUPT CALLS
                          (Applies to Stacker 4.0)

      BACKGROUND
      
      The Basic Input/Output System (BIOS) of some computers does not
      support certain interrupt calls. Stacker uses these INT 1AH
      calls, as do other compression drivers. Microsoft has reported
      this incompatibility with the following computers (this is not a
      complete list):
      
      Sharp models 6700, 6781, 6785, 6800 and 6881
      Cannon C-200 M-50
      Computers using a Microsolutions Compaticard
      Positive Computers
      Snap-On Intel 386 and Intel AboveBoard 2.0
      Some AEG Olympia 386SX Laptops
      Some older ACER machines
      Texas Instruments (TI) Travelmate 2000
      Zeos 80386 with an AMI BIOS dated 09/15/89
      
      During Setup on these systems, your computer may hang during
      restart and Setup will not finish.
      
      SOLUTION
      
      Read through these directions completely before proceeding.
      
       1.  Make a DOS startup disk. Test the disk to make sure it works
           before proceeding. This disk must not try to mount any
           Stacker drives. If you have a previous version of Stacker
           installed, see StacFax 3304 to make a boot disk that does
           not mount your Stacker drives.
       2.  Back up your data. Stacker is safe, but before making any
           major system change it is prudent to have a current backup.
       3.  Put Stacker Disk # 1 into its drive and type A:SETUP /-LZS
           (or B:SETUP /-LZS) and press <enter>. If you are installing
           Stacker from Windows, open the Program Manager's File menu
           and choose Run. Then type in the command above.
       4.  After Setup copies the Stacker files to the hard disk, the
           system will reboot (restart) to disable memory-resident
           programs. Use the procedure below to restart without
           hanging.
       5.  Restart your system without Stacker. Insert your DOS startup
           disk and restart your system.
       6.  Go to drive C and change to the Stacker directory. Type:
           SATTRIB -S -H -R C:\STACKER.INI <enter>
           ED C:\STACKER.INI <enter>.
       7.  Press <enter> to insert a blank line. Add the statement "/-
           LZS" on this line by itself. Do not type the quotation
           marks. Press CTRL-Z to save the file.
       8.  Remove the boot disk from drive A and restart your system.
           Setup will now continue.
       9.  After Setup compresses the drive, it will restart to mount
           your new Stacker drive. Insert your boot disk to restart
           without Stacker.
       10. Go to drive C and change to the Stacker directory. Type:
           SATTRIB -S -H -R C:\STACKER.INI <enter>
           ED C:\STACKER.INI <enter>.
       11. Examine the file for the statement "/-LZS". If it exists,
           press CTRL-Z to exit. Remove the boot disk from the computer
           and restart your system. The Setup will now complete.
       12. If the statement does not exist, then add it. Press <enter>
           to insert a blank line. Add the statement "/-LZS" on this
           line by itself. Do not type the quotation marks. Press CTRL-
           Z to save the file.
       13. Remove the boot disk from the A drive and restart your
           system. The Setup will now complete.
       14. Please note that each time your system restarts during Setup
           it hangs unless you use the boot procedures above. If you
           run Setup on more than one drive, or use a Custom Setup, you
           may experience additional restarts. If so, simply follow the
           procedures above to restart the system without Stacker, edit
           the STACKER.INI file to restore the "/-LZS" expression, and
           restart. Setup will continue normally. After Setup is
           finished, the system will no longer hang at restart.
