  • Page 39: Protecting Your Data

    It is a good idea to make backup copies of all your data and system diskettes. Copy all diskettes that contain programs, such as the MS-DOS and GW-BASIC diskettes that come with the Equity II, and use only the copies. Store your original software diskettes in a safe place away from your working diskettes.

    Usually, operating systems expect the computer to have at least two physical disk drives and display prompts and messages accordingly If your Equity II has only one floppy disk drive, turn on (up) DIP switches and 1-8 under the cover beneath the disk drives. When these switches are on, the operating system treats your single drive like two logical drives.
