EXP Computer CD-820_CDG-820 - Manual (Page 16)

MANUAL INSTALLATION
You may manually install the device driver if the default setting conflicts with your
system. Try the following procedure to complete the manual installation.
1) Copy the file named EXPCDG.EXE to a directory on your main hard disk. ( i.e.
C:\CDROM).
2) Edit the config.sys add the following line at the end of the file.
DEVICE=[drive] [path] EXPCDG.EXE /P:320 [/G]
/P is used to set the I/O ports, and the valid numbers are 320, 340 and 360.
Each number represents the I/O port address - 320-32F, 340-34F, and 360-
36F respectively.
The default setting is /P:320
/G Add this to the end of the line, if you want to enable game port
The config.sys file example
LASTDRIVE=Z
DEVICE=C:\DOS\HIMEM.SYS
DEVICE=C:\DOS\EMM386.EXE NOEMS X=D000-D3FF
FILES=40
BUFFERS=20
STACKS=9,256
DEVICE=C:\CDROM\EXPCDG.EXE /P:320 /G
If you use the memory manager just like the example above (EMM386.exe). You
need to exclude the memory range for the hard disk card and X=D000-D3FF is
recommended.
3.) Reboot the system so the new driver will take effect.
