                      Installation Instructions
          SCO UNIX LLI Driver for the 3Com 3C90X Adapter Family


Below are instructions for creating an SCO "custom" installation diskette
containing the LLI device driver for 3Com's 3C90X network adapter family.
Once a the diskette is created, follow the SCO instructions for using the
"custom" and "netconfig" utilities to install the driver.

To begin, place the 3C90XLLI.A file on a DOS formatted diskette.  3C90XLLI.A is an
ASCII encoded, compressed, SCO UNIX diskette image file.  Place the diskette
in drive A on a computer with SCO UNIX installed.  If you wish to use drive
B, adjust the instructions below appropriately.

Now enter the following commands at the UNIX prompt.  Remember, UNIX is
case sensitive.

   doscp a:3C90XLLI.A 3C90XLLI.A  (copies from DOS disk to current working directory)
   uudecode 3C90XLLI.A       (decodes the ASCII file to binary compressed, 90X.Z)
   uncompress 90X.Z     (uncompresses 90X.Z and changes name to 90X)

Now place the diskette you want to become the installation diskette in
drive A.  This should be a UNIX formatted, high density diskette.  Again,
if you wish to use drive B, adjust the instructions below appropriately.

If drive A is a 5.25" diskette drive, enter the following command:

   dd if=90X of=/dev/rfd096ds15 (transfers disk image to diskette)

If drive A is a 3.5" diskette drive, enter the following command:

   dd if=90X of=/dev/rfd0135ds18 (transfers disk image to diskette)

The diskette is now ready to use with the SCO "custom" utility.
