The config.sys should look like:
The autoexec.bat should look like:
set blaster=a220 i7 d1 set ultrasnd=220,5,5,7,7
You can load additional drivers (mouse, cdrom) if you like. Most drivers only use dos memory below 1MB and therefore do not steal memory above 1MB that OPENCP has to use. But please do not load programs such as smartdrv or ramdrive as they use XMS/EMS memory, which will then not be available anymore.4.16
The set statement for the sound card installed should be present in the autotexec.bat so OPENCP knows what sound cards to search for.
