NAME

       ibmtr_cs - IBM Token Ring PCMCIA device driver

SYNOPSIS

       insmod ibmtr_cs.o [pc_debug=n] [mmiobase=n] [srambase=n] [ringspeed=n] [irq_list=i,j,...]

DESCRIPTION

       ibmtr_cs  is  the  low-level Card Services driver for the IBM Token Ring network adapter and a few very similar cards.  When this driver is
       attached to a card, it allocates the next available token ring interface (tr0..tr#).  This device name will be reported in the  kernel  log
       file, and passed on to cardmgr(8).

       Due  to awkward design of the kernel ibmtr driver, the shared packet memory for these cards must be mapped to a memory address below 1MB or
       0x100000.  The PCMCIA software will attempt to do this automatically, but the automatic algorithm may  choose  values  that  conflict  with
       other  system devices, so a manual override with the srambase parameter may be required.  The memory-mapped IO window generally will not be
       a problem.

PARAMETERS

       pc_debug=n
	      Selects the PCMCIA debugging level.  This parameter is only available if the module is compiled with debugging enabled.  A  non-zero
	      value enables debugging.

       mmiobase=n
	      Specifies a fixed address for the card's memory mapped IO window.  The default is to select any available memory window.

       srambase=n
	      Specifies a fixed address for the card's shared packet memory.  The default is to select any available window below 1MB.

       ringspeed=n
	      Selects the network speed, in mb/sec.  Valid values are 4 or 16, and the default is 16.

NAME

       dummy_cs - PCMCIA dummy device driver

SYNOPSIS

       insmod dummy_cs.o [pc_debug=n] [free_ports=n] [irq_list=i,j,...]

DESCRIPTION

       The dummy_cs module has two purposes.  It is intended as a demonstration of how to write the PCMCIA interface code for a client driver, and
       the source code is heavily commented.  It is also written to function as a sort of generic ``point enabler'': when bound to any	PCMCIA	IO
       card,  it  will read the card's Configuration Information Structure, and configure the card appropriately.  The configuration includes set-
       ting up IO and memory windows, configuring the card for interrupts, and initializing the card's PCMCIA configuration registers.

       It turns out that many cards report incomplete or inaccurate configuration information, due to vendor carelessness and  the  complexity	of
       the  data format.  A vendor driver can generally take for granted many configuration details, so there is not much incentive for vendors to
       ensure that the on-card information is complete.  Thus, the dummy_cs module is limited by its generality: since	it  makes  no  assumptions
       about card types, it is forced to rely on the card information, for better or worse.

PARAMETERS

       pc_debug=n
	      Selects  the PCMCIA debugging level.  This parameter is only available if the module is compiled with debugging enabled.	A non-zero
	      value enables debugging.

       free_ports=n
	      A flag indicating if the IO ports allocated for the card should be freed from the kernel resource maps.  This is useful if the dummy
	      driver is being used to configure a card in preparation for loading a specific PCMCIA-unaware driver.  The default is 0 (false).

       irq_list=i,j,...
	      Specifies the set of interrupts that may be allocated by this driver.
