The Computone FTP site and BBS contain drivers for all products and operating
system supported.  This document contains directions for creating an
installation diskette for UNIX/XENIX systems from a dd image obtained from
our ftp site or BBS.


1. Introduction

	The drivers are loaded on the system by using the XENIX/UNIX
	"dd" command.  They are then compressed using the "compress"
	command.  Compressed files end with the .Z extension; the
	uncompressed files end with the .dd extension.  Both the
	compressed and uncompressed versions are available.


	Special Note for SCO XENIX/UNIX Users:

		While most driver diskettes will be in TAR format, resist
		the temptation to "tar" the files from the image and
		to "tar" the extracted files to the destination diskette.
		The order of the files on the diskette is important.  Use
		"dd" to ensure that an exact image is created.


2. Moving the downloaded file to UNIX from a DOS diskette

	If you FTP'd the driver image, proceed to the step 3.

	Copy the downloaded file to a DOS floppy disk.  On your UNIX/XENIX
	system, insert the floppy and copy the file to your UNIX/XENIX
	hard drive as follows:

		cd /tmp
		doscp a:filename .

	Note that filename should be in lower-case except for a trailing
	.Z, if any (i.e. i2sco132.Z, not I2SCO132.Z as in DOS).  The resulting
	file will be placed in the /tmp directory.

	Substitute b: for a: to use the second floppy drive.


3. Uncompressing the image file

	If the file downloaded was compressed, you need to run the
	"uncompress" command on it.

		uncompress filename.Z


4. Creating the installation diskette (not Interactive UNIX 3.2 w/3.5" disk)

	(NOTE:	if you are using AT&T UNIX 3.2 or Interactive UNIX 3.2 
		and a high density 3.5" diskette, see the next section
		for special instructions)

	A UNIX/XENIX formatted diskette will be needed.  The driver may be
	stored as either a high or low density diskette image.  View the
	uncompressed file with the "ls -l" command to get the file size.
	The table below will help you determine the size diskette you will
	need.  Note that a 720k image can be placed on a low density 3.5"
	diskette or a high density 5.25" diskette.

		File Size	Disk Density

		368640		low  density 5.25"
		1228800		high density 5.25" or high density 3.5"
		737280		low  density 3.5" or high density 5.25"
		1474560		high density 3.5"


	NOTE: You must "dd" a file to a diskette that is larger or
	the same size but not to a diskette that is smaller.

	Use one of the following commands to place your diskette image
	onto your formatted floppy disk:

		For a 3.5" low density diskette as drive 0:
			dd if=filename of=/dev/dsk/f0q9dt

		For a 3.5" high density diskette as drive 0:
			dd if=filename of=/dev/dsk/f0q18dt

		For a 5.25" high density diskette as drive 0:
			dd if=filename of=/dev/dsk/f0q15dt

	To use drive 1 instead of drive 0, replace the f0q in the appropriate
	example with f1q.

	Skip to step 6.

   
5. Creating the installation diskette for AT&T UNIX 3.2 or Interactive UNIX 3.2
   using a high density 3.5" diskette

	This section does not apply to SCO UNIX or XENIX, nor to
	UNIX SVR4 streams drivers.  Those can be transferred using
	ordinary dd commands as described in the previous section.

	If you are dd'ing onto a 3.5" high density diskette you must use
	the following dd command to create your installation diskette.
	This is because the "boot track", which must be skipped, is of
	different length between 5.25" and 3.5" diskettes and we only
	supply the 5.25" driver image.

   		dd if=filename of=/dev/dsk/f0q18dt bs=1k skip=15 seek=18

	To use drive 1 instead of drive 0, replace the f0q with f1q.


6. Install the driver

	Now that you have made a installation floppy you can follow the
	installation instructions provided in your manual or release notes.
