If you want to install a sound card after installing UnixWare 7 and the LKP, you need to do the following to enable Linux application to use it. Sound card configuration is performed entirely on the Unix side; only the configuration of Linux applications to use the card is done from the LKP side.
Install the sound card in your system using scoadmin audio from a UNIX shell or desktop.
Download the Open Sound System (OSS) from (They provide a free evaluation copy, but charge for a permanent license.)
Select the UnixWare 7 version of the OSS and follow their installation instructions. Note the device node under /dev used by the audio card.
Verify that the sound card is working on UnixWare 7 in UNIX mode using OSS.
Determine the major node of the UnixWare 7 audio device node:
ls -l /dev/audio-device
Do this from a Unix shell: you need the major number of the UnixWare 7 device node, not the Linux device node.
In the output of ls, the major and minor numbers are listed in the column before the date, separated by a comma; as in the following example, where 29 is the major number:
crw-rw-rw- 1 bin bin 29, 0 Apr 7 1998 audio
Change directory to /linux/lxinst/dev.
cd/linux/lxinst/dev
Copy the following script into a file name mkaudio.sh in the current directory:
#!/bin/sh
umask 111

mknod mixer3 c $1 48
mknod mixer4 c $1 64
mknod music c $1 8
mknod sequencer c $1 1
mknod sndstat c $1 6
Run the script as follows, using the major number of the UnixWare 7 audio device obtained previously:
sh ./mkaudio.sh major#
You should now be able to configure a Linux application under LKP to use the audio card you just installed.
