Switch 1, use of parallel port-Thisswitch tells your computer whether a diskette drive or a parallel printer is connected to the parallel port. If you have connected a parallel printer to this port, set switch 1 off. If you have connected an external 5 1/4-inch diskette drive to the port, set switch 1 on.
WARNINGFailure to set switch 1 correctly may result in damage to your system.
Switch 2, external drive assignment-If you have connected an external diskette drive to the computer, switch 2 determines whether MS-DOS and your application programs access the drive as drive A or drive B. If this switch is on, the built-in 3 1/2-inch diskette drive is drive A and the external 5 1/4-inch diskette drive is drive B. If this switch is off, the internal drive is B and the external drive is A.
Certain copy-protected application programs require that an original program diskette be in drive A when the program is started. If you are running such a program and the original diskette is 5 1/4- inch, be sure to set switch 2 off. Under all other circumstances, it is best to leave it on.
Switch 3, primary or secondary serial port-Thisswitch tells the computer whether the serial connector on the back of the computer is configured as a primary port (COM1) or a secondary port (COM2). If this switch is off, MS-DOS recognizes this connector as COM1; if it is on, MS-DOS recognizes it as COM2.
If you have not installed an internal modem in your Equity LT-286, you probably want to leave switch 3 off. If you have installed an internal modem, and you want the modem’s own serial port to be COM1, set this switch on.
Switch 4, double-dot/single-dotselect-This switch controls the intensity with which characters are displayed on the screen. Set this switch on for bold (double-dot) characters or off for light (single-dot) characters.
