If you want to save the settings you entered, highlight

screen. The Setup program stores the new settings and resets
the computer using the new configuration. If you have set a
password, you need to enter it at the key prompt. (See “Using
a Power-on Password” in Chapter 3 for instructions.) The
Operation Menu appears.
If you have just run Setup for the first time, remove the
Reference diskette from the drive and turn off your computer.
Then follow the instructions in your MS-DOS manual to install
the operating system. (If you are using a different operating
system, follow the installation instructions in that manual.)
Once you have installed MS-DOS, you should always boot the
computer from the hard disk or the MS-DOS Startup diskette
when you are finished running Setup. First remove the
Reference diskette from drive A. If you do not have a hard disk,
insert the Startup diskette. Then reset your computer to make
sure it performs all the commands in the CONFIG.SYS and
AUTOEXEC.BAT files.
If the computer displays an error message while it is starting
up, run the Setup program again and check the setting the error
message indicates. If the computer still displays an error
message after you check your Setup program settings, see
Appendix B or C, or ask your dealer for assistance.
Be sure to make a backup copy of your Reference diskette
