DESCRIPTION    [Toc]    [Back]

     The pcmcia subsystem provides machine-independent  bus  support and drivers
     for PCMCIA (PC Card) devices.

   IDE controllers    [Toc]    [Back]
        wdc(4)         Devices  which implement an ATA/IDE interface, such as
                      mini disk drives,  CDROMs.   This  includes
Compact Flash
                      cards which emulate a disk drive.

     The  supported  PCMCIA controllers are those that are i82365

NOTES    [Toc]    [Back]

     On some pcmcia  adapters,  for  instance  the  sbus(4)-based
stp(4), the
     pcmcia  bus  will  be mapped in big-endian format instead of
the natural
     (and preferred) little endian  format.   Unfortunately  such
     lack  the hardware facility to swap bytes, and it is not efficient to convert
 all drivers to always know about  this.   While  8  bit
drivers can invisibly
 work on such a bus, 16 bit drivers will need modification to handle
 this.  So far, wi(4) is the only driver to require these

     If  the  pcmcia adapter is not detected, or if pcmcia events
(such as card
     insertion) do not occur, there may be a PCI card BIOS mapped
in the same
     memory space the pcmcia driver is configured to use (this is
often the
     case  with  Ethernet  card  boot  ROMs).   The  output  from
dmesg(8) should contain
  a  line beginning with ``bios0'' that lists the memory
address and
     size of mapped regions.  If there is a conflict, you can use
     boot_config(8) to change the iomem parameter of the pcic device to a nonoverlapping
 address, such as 0xd8000 for pcic0.  Some experimentation may
     be  required to find a working value; in some cases the size
parameter of
     the pcic device may need to be decreased  to  avoid  a  conflict.
