-This file documents the bpcd driver for the MicroSolutions backpack CDrom,
-an external parallel port device.  
-
-There are apparently two versions of the backpack protocol.  This 
-driver knows about the version 2 protocol - as is used in the 4x 
-and 6x products.  There is no support for the sound hardware that
-is included in some models.  It should not be difficult to add 
-support for the ATAPI audio play functions and the corresponding 
-ioctls.
-
-The driver was developed by reverse engineering the protocol
-and testing it on the backpack model 164550.  This model
-is actually a stock ATAPI drive packaged with a custom 
-ASIC that implements the IDE over parallel protocol.
-I tested with a backpack that happened to contain a Goldstar
-drive, but I've seen reports of Sony and Mitsumi drives as well.
-
-Before attempting to use the driver, you will need to
-create a new device special file.  The following commands will
-do that for you:
-
-		mknod /dev/bpcd b 41 0
-		chown root:disk /dev/bpcd
-		chmod 660 /dev/bpcd
-
-Afterward, you can mount a disk in the usual way:
-
-		mount -t iso9660 /dev/bpcd /cdrom
-
-(assuming you have made a directory /cdrom to use as a mount point).
-
-The driver will attempt to detect which parallel port your
-backpack is connected to.  If this fails for any reason, you
-can override it by specifying a port on the LILO command line
-(for built in drivers) or the insmod command (for drivers built
-as modules).   If your drive is on the port at 0x3bc, you would
-use one of these commands:
-
-		LILO:	   bpcd=0x3bc
-
-		insmod:    insmod bpcd bp_base=0x3bc
-
-The driver can detect if the parallel port supports 8-bit
-transfers.  If so, it will use them.  You can force it to use
-4-bit (nybble) mode by setting the variable bp_nybble to 1 on
-an insmod command, or using the following LILO parameters:
-
-		bpcd=0x3bc,1
-
-(you must specify the correct port address if you use this method.)
-
-There is currently no support for EPP or ECP modes.  Also,
-as far as I can tell, the MicroSolutions protocol does not
-support interrupts in the 4-bit and 8-bit modes.
-
-MicroSolutions' protocol allows for several drives to be
-chained together off the same parallel port.  Currently, this
-driver will recognise only one of them.  If you do have more
-than one drive, it will choose the one with the lowest id number,
-where the id number is the last two digits of the product's
-serial number.
-
-It is not currently possible to connect a printer to the chained
-port on the BackPack and expect Linux to use both devices at once.
-If you need to use this driver together with a printer on the
-same port, build both the bpcd and lp drivers as modules.
-
-Keep an eye on http://www.torque.net/bpcd.html for news and
-other information about the driver.  If you have any problems
-with this driver, please send me, grant@torque.net, some mail 
-directly before posting into the newsgroups or mailing lists.
