DESCRIPTION

       Pcmcia_core is the core Card Services module, required for all drivers for specific PCMCIA cards.  It is loaded prior to loading any socket
       device drivers.

       In the event that kernel version mismatches prevent this module from being loaded, version information can be  extracted  from  the  module
       itself by doing:

	      strings -n 10 pcmcia_core.o | head -3

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.

       setup_delay=n
	      Sets the delay between when a card is first detected, and when it will be powered up.  In 1/100 second increments, the default is 5.

       resume_delay=n
	      Sets the delay between when a resume event is processed, and when a suspended card will be powered up.  In 1/100 second  increments,
	      the default is 20.

       shutdown_delay=n
	      Sets  the  delay	between  when when a card removal event is detected, and when the socket will be disabled.  In 1/100 second incre-
	      ments, the default is 5.

       vcc_settle=n
	      Sets the time to wait after first applying power to a socket before accessing a card.  In 1/100 second increments,  the  default	is
	      40.

       reset_time=n
	      Sets how long the software reset signal will be asserted, in microseconds.  The default is 10.

       unreset_delay=n
	      Sets  the delay between when a card is reset, and when the card will first be checked to see if it is ready.  In 1/100 second incre-
	      ments, the default is 10.  This delay should be increased for cards that raise the ready signal prematurely.

       unreset_check=n
	      Sets how often to check to see if a card is ready after it is sent a software reset.  In 1/100 second increments, the default is 10.

       unreset_limit=n
	      Sets the maximum number of checks to make before pronouncing a card to be dead.  The default is 50 (i.e., 5 seconds).

       cis_speed=n
	      Sets the access delay in nanoseconds for CIS memory windows.  This parameter only affects card identification.  The default  is  300
	      ns.

       cis_width=n
	      If this flag is set, then CIS windows are configured for 16-bit transfers.  The default is 0 (i.e., use 8-bit transfers).

       io_speed=n
	      Sets the access delay in nanoseconds for IO port windows.  The default is 0.

       probe_io=n
	      A flag indicating if Card Services should probe IO port regions for conflicts with other devices unknown to Linux.  The default is 1
	      (true).

       probe_mem=n
	      A flag indicating if Card Services should probe memory windows for conflicts with ROM  extensions  or  memory-mapped  devices.   The
	      default is 1 (true).

       cb_mem_base=n
	      Sets  the  base address to use for memory mapping CardBus bridge registers.  By default, bridges that are not already initialized by
	      the PCI BIOS will be mapped at 0x68000000.  If this parameter is set, then this value will override any existing mappings.

       cb_bus_base=n
	      Specifies that PCI bus numbers for CardBus busses should be renumbered starting with this value.	By default, bus  values  that  are
	      uninitialized at boot time will be numbered starting with bus 0x20.

       cb_bus_step=n
	      Specifies  the  number  of  bus slots to reserve for secondary PCI busses, for each CardBus socket, when busses are renumbered.  The
	      default is 2.

       cb_pci_irq=n
	      Specifies an interrupt number 1..15 to be assigned to any CardBus bridge whose PCI interrupt was not set by the BIOS.   The  default
	      is to pick an interrupt based on the BIOS PCI Interrupt Routing table only when the table is unambiguous.
