3. Software Notes and Recommendations

This driver needs UnixWare 1.1 to be installed on the system. After this
package is added the system is to be rebooted to incluse the new driver 
in the system kernel. The old driver will be saved in the directory
/var/sadm/pkg/ptf126/etc/conf/pack.d/st01. In case if the package can 
not be removed using pkgrm, restore the system by copying Driver.o 
from the above specified directory to /etc/conf/pack.d/st01. And also 
the directory "/var/sadm/pkg/ptf126" is to be removed from the system. 
Then the kernel is to be rebuilt and the system is to be rebooted with 
new kernel.

update 1.1.1
