Apple Macintosh LC 630 DOS - Manual (Page 137)

Replacing the CONFIG.SYS and AUTOEXEC.BAT files
Your DOS-compatible PC software includes alternate versions of the
CONFIG.SYS and AUTOEXEC.BAT files that let you select from a variety of
DOS memory-management options. Each time you start DOS, you will see a
menu that asks if you want to optimize memory for just DOS, for a DOS
program that requires maximum conventional memory, for a DOS program
that requires maximum expanded memory, or if you want to start Windows
immediately.
To install the alternate CONFIG.SYS and AUTOEXEC.BAT files, follow
these instructions:
1 Switch to the PC environment.
2 At the DOS prompt, type the following:
C:
REN CONFIG.SYS CONFIG.BAK
REN AUTOEXEC.BAT AUTOEXEC.BAK
COPY ALT_CFGS\CONFIG.APL CONFIG.SYS
COPY ALT_CFGS\AUTOEXEC.APL AUTOEXEC.BAT
3 To restart the PC with the alternate files installed, type Control-Alt-[keypad] period.
If your keyboard has a Delete key, you can press Control-Alt-Delete instead.
The PC restarts and the new menu appears.
Modifying the CONFIG.SYS and AUTOEXEC.BAT files
You may want to modify the CONFIG.SYS file by hand to meet specific
needs. Use the DOS Edit command (or any other DOS or Windows editor)
and make the changes listed below.
IMPORTANT Make backup copies of your original files before you change
them. That way you still have your originals in case problems develop.
Be sure to save the file when you are finished. To prevent the ROM BIOS
from becoming corrupted when the PC is configured for 2 MB of memory, be
sure to add the underlined text to the indicated line:
DEVICE=C:\DOS\HIMEM.SYS/ TESTMEM:OFF
