 4.3 Insert a Diskette

  

 PICTURE 4

  

  

 Each time the system is powered on or a system reset is performed, the

 system looks for an operating system.  If the operating system is not

 found, this icon is displayed.  It instructs the user to insert a diskette

 containing the operating system into diskette drive A, then press the F1

 key to resume operation.

  

 If the F1 key is pressed prior to inserting the diskette, the system

 automatically loads BASIC from the ROM BIOS.
