Appendix B / Configuring }Our System
Changing CONFIG.SYS
If CONFIG.8YS is already on your diskette, before creating a
new file be sure it does not contain data you want. To read an
existing file, type:
t y P e con fig. s Ys
I
ENTER
I
CONFIG.SYS is listed to the screen. If you wish to create a new
CONFIG.8YS file, but want to be able to re-establish the same
configuration later, rename the existing CONFIG.8YS file. For
example, type:
ren config.sys config.old
[ENTER
I
You now have a file named CONFIG.OLD on your diskette. You
can later change the name back to CONFIG.SYS to re-establish
the same configuration. To do so, first delete or rename the cur-
rent CONFIG.8YS file, then type:
r e nco n fig. old t
0
con fig. s Y s
I
ENTER
I
To expand an existing CONFIG.8YS file to add a new device
driver, you might type:
cop y con fig . s Y s
+
con
I
ENTER
I
device=myprint .prt
I
ENTER
I
IT[]
I
ENTER
I
The command DEVICE
=
MYPRINT is appended to the current
CONFIG.SYS file.
To create a totally new CONFIG.SYS file with 20 buffers,
BREAK set to ON, and a new printer driver, you might type:
cop y con con fig . s Y s
I
ENTER
I
buff e r s
=
2 0 [ENTER
I
b
rea k
=
0
n [
ENTER
I
devlce = myprint .prt
I
ENTER
I
IT[]
I
ENTER
I
You can create a new CONFIG.8YS file at anytime with such a
procedure. The new file you create overwrites any old CON-
FIG.SYS file. Be sure the CONFIG.8YS file you create is in the
root directory.
See the COPY command in Chapter 6 and Chapter 4, "Batch
Files," for more information on using COPY and CON.
