INSTALLATION GUIDE - PCI/059/100


	       CHASE RESEARCH LINUX DRIVER FOR THE XX-FAST FAMILY


				  VERSION 2.02





	This software is distributed in the form of a tar archive.
	The archive contains:
		a. the driver source (chaser.c) and associated
		   header files (chaser.h, st16654.h)
		b. a replacement binary for stty (with source)
		c. a replacement binary for setserial (with source)
		d. an install script
		e. a removal script

	The steps to carry out are:

	1. Install your PCI-Fast and PCI-RAS cards before installing
	   the software. This is important. AT-Fast cards, if any,
	   can be installed later.

	2. As root, make a temporary directory e.g. /chase
		# mkdir /chase

	3. Change directory to this new directory
		# cd /chase

	4. Insert the distribution diskette into the floppy disk drive

	5. Extract the archive
		# tar xvf /dev/fd0

	6. Run the install script
		# ./install

	The install script will make backup copies of the files it is
	about to replace or modify. It will then remind you of the 
	importance of installing PCI-Fast/PCI-RAS cards first and offer 
	an opportunity to terminate the script. It will then ask how many 
	AT-Fast cards you want to install. Answer this question now, even 
	if you deferred installing the hardware until later. The default 
	number of AT-Fast cards is 0.

	If you elect to install one or more AT-Fast cards, you will be
	prompted for the Base I/O address, the interrupt level (IRQ) and 
	the number of ports in turn. Note that:
		cards require exclusive use of n bytes of contiguous I/O space
		where n is 32 for 4-port cards
		           64 for 8-port cards, and
		          128 for 16-port cards.
		each card requires exclusive use of an IRQ
		the jumpers on the card must match the settings entered.

	After entering the AT-Fast settings, you will be asked if you
	want settings for PCI-Fast/PCI-RAS to be detected automatically
	or entered manually. Choose automatic unless a previous attempt
	failed.

	The script will then copy the replacement files to the appropriate
	places (the sources for the replacement stty and setserial binaries
	are placed in a new directory /usr/src/chase). Some system files 
	are edited in place after backups have been made. The required 
	device nodes in /dev are created and setserial entries added to 
	/etc/rc.d/rc.serial.

	Finally, the script prompts you to rebuild the kernel with a
	pointer to the appropriate README. On uni-processor systems, the
	driver may be permanently linked into the kernel or may be added
	as an installable module. On multi-processor systems the loadable
	module approach doesn't (yet) work.
	After the rebuild, reboot and your Chase ports will be operational. 

	At this point the temporary directory can be removed. e.g
		# rm -rf /chase


	DEVICE NAMES
	Device names follow the convention below:
	'Normal' ports on the first card are ttyCH0 to ttyCH3, ttyCH7 
	or ttyCH15 depending on whether the card is 4, 8 or 16-port. 
	Callout devices on the first card are cuch0 to cuch3, cuch7 or cuch15.
	Similarly, the second card offers ttyCH16 to ttyCH31 and cuch16 
	to cuch31, the third card ttyCH32 to ttyCH47 and cuch32 to cuch47 
	and the fourth card ttyCH48 to ttyCH63 and cuch48 to cuch63.

	REMOVAL
	The Chase driver can be removed by running the script 
	/usr/lib/chase/remove as root.
