Automatic Configuration
Your computer automatically defines your system’s memory
configuration and recognizes whether the CPU chip contains a
math coprocessor. It also detects and configures most of the
devices you have installed in your system. For this reason, you
may not need to change any of the default settings in the Setup
program. However, you should check each of the options on
the Setup menu to verify that the settings are correct for your
configuration.
The computer automatically configures the 4MB of memory
that comes with your system as 640KB of base memory and
3072KB of extended memory. If you install even more memory,
Setup configures it as extended memory also.
Note
To run certain application programs, you may need to
reduce the amount of base memory from 640KB to 512KB or
256KB. Check the documentation that came with your
software to see if this is necessary. If you do need to change
the amount of base memory, you must set jumpers on the
computer’s main system board. See “Changing the Jumper
Settings” in Chapter 6 for instructions.
Starting the Setup Program
Follow these steps to start the Setup program:
1. Make sure your computer is turned off.
2. Insert the Reference diskette in drive A. (If you have a
drive, the diskette clicks into place automatically.
If you have a drive, press the button to secure the
diskette in the drive after you insert it.)
