Backing-up the pre-installed software

Apricot computers with a hard disk normally arrive with an operating system pre-installed. The hard disk also contains a complete set of Cirrus Logic video display drivers, although initially the computer is configured to use the standard VGA Windows driver. Additional software may be pre-installed by your supplier.

We recommend that you copy or back up any pre-installed software soon after setting up the system. This is particularly important for systems which are supplied without installation diskettes for the software on the hard disk. A back up copy will safeguard the pre- installed software against loss if the hard disk fails or if you accidentally overwrite or delete files.

♦A disk imaging utility is provided with Windows 95 and Windows for Workgroups. This allows you to create installation diskettes for the operating system, and some other software, from disk images pre-installed on the hard disk. See the utility’s on-line help for more information.

♦To back up other pre-installed software (and your own files) use the Backup tool in the System Tools folder (if you have Windows 95) or Backup for Windows (if you have Windows for Workgroups).

Any copy you make of pre-installed software must be used only as a back-up copy, in case the pre-installed version is lost. You are not allowed to use installation diskettes created from disk images to install the software onto another computer.
