Copy the .bin file from the CD or the Digi ftp site onto your UNIX server, copy it to a volume name that SCO's custom utility will recognize as an installation image:
# cp 40001044_P.bin VOL.000.000
That's "vee oh el" all the rest are zeros.
If installing MPI, the second image will need to be called VOL.001.000.
Next, install the driver using SCO's custom utility:
Select Install New Software, select as a media image and type in the path to where the VOL file(s) resides.
