IBMTR_CS(4)                                           IBMTR_CS(4)

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 sys-
       tem devices, so a manual override with the srambase param-
       eter  may be required.  The memory-mapped IO window gener-
       ally 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 debug-
              ging.

       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 avail-
              able window below 1MB.

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