to which you must respond 'YES' before copying will take place.

If you have two disc drives then you can copy one disc to another without

having to swap discs by putting the original disc in one drive and a blank

formatted one in the other; you can then type:

*BACKUP 0 1 RETURN

Using the ADFS

Before you start reading this section you might like to know that there is a

tutorial program on the Welcome disc which teaches you about the ADFS. You

can call it up by selecting it from the main menu in the Icon software, which

was covered at the beginning of this guide.

Initialising the ADFS

Normally, the ADFS is the filing system which is automatically selected by the

computer when switched on. However, if you have other optional software in

the computer then you may need to select the ADFS explicitly, by typing:

*ADFS RETURN

which will cause the light on the left-hand drive to glow. The ADFS is now

waiting for a disc, so put the Welcome disc into the drive with its label

uppermost and the metal shutter nearest the drive. It is impossible to insert a

disc the wrong way around, as you will quickly discover if you are trying to do

so. NEVER try to force a disc into a drive as you stand a good chance of

damaging both. Once you have inserted it the ADFS will spend a couple of

seconds reading information from the disc and it is then ready for use.

If you want to use the other disc drive you need to start up the ADFS 'quietly',

ie. without accessing the drive, and then tell it where to find your disc with the

*MOUNT command, thus:

*FADFS RETURN

*MOUNT 1 RETURN

The *FADFS command tells the ADFS to prepare for work but does not cause it

to access either drive. The *MOUNT 1 command instructs the ADFS to refer

henceforth to the disc in drive 1. If you wish to change drives again you need to

type:

*DISMOUNT RETURN

to allow the ADFS to 'release' the disc in drive 1, and then issue a *MOUNT

command to tell the ADFS where the new disc is, e.g.:

*MOUNT RETURN
