Running the Setup Program
If this is the first time your Equity LT-286 has been used, you need
to run the setup program on the Reference diskette to give the
computer information about the way it is set up. This is a simple
procedure that you must do at least once. You may need to do it
again later if you want to change a setting.
The setup program lets you specify the following:
The amount of random access memory (RAM) in your
computer
The type of display you’re using
Whether or not you have installed an 80287 math coprocessor
Whether or not you have installed an external 5 1/4-inch
diskette drive
What type of hard disk drive you have
The backlight period for your LCD screen
The mapping of colors to gray tones for gray-scale mode 3.
The settings you specify with the setup program are recorded in a
special area of memory called CMOS RAM. This memory is backed
up by a battery, so it cannot be erased when you turn off or reset the
computer. Whenever you turn on the computer, it reads the
settings stored in CMOS RAM. If there are any differences
between those settings and the settings of your DIP switches, the
computer prompts you to rerun the setup program.
