Louis,
No.... the only things you have to do :
First save your personal files e.g. Block registrations to the internal harddisk of the SD1
After you saved the following steps :
1. Unzip the SD1STAN.EXE to a blank floppy disk.
2. Put the floppy into the SD1 drive.
3. Switch power on, while holding the F6 button for 2 or 3 seconds.
After a few minutes the display shows "OS4.0b" ..... that's all !
