Prior to removing, you may want to make backup copies of the following files: /etc/inittab and /etc/ttytype files to save port configurations.
Remove the old driver using SCO's custom utility.
# cd /mount_path/drivers/sco_unix
The ls command should show the driver image in that directory it will be labeled with a 40 million part number, followed by revision letter(s). Copy the driver image to a path on your hard drive and rename the file to: VOL.000.000 (V-OH-EL, the rest are all number zeros).
Installing as Media Image:
Select "Media Image" from the drop down list for Media device.
Type in the pathname to the directory where the VOL images reside.
