PCMCIA bridges for desktop systems

Card readers for desktop systems

While almost all PCMCIA card readers and card docks work fine under
Linux, some require special startup options because they do not behave
exactly like laptop PCMCIA bridges. PCI card readers, in particular,
may handle interrupts differently.

· The Linksys ProConnect PCMRDWR and Antec DataChute card readers are
``ISA Plug and Play'' devices. To use these, you must first
activate them with the Linux isapnp tools. See the man pages for
pnpdump and isapnp for more information.

· For Elan P-series PCI card readers based on the Cirrus PD6729 PCI-
to-PCMCIA bridge chip, the i82365 driver requires a ``irq_mode=1''

· For the Sycard PCChost1200 host adapter, the i82365 driver requires
a ``p2cclk=1'' parameter.

· For the Alex Electronics PCICBI host adapter based on the TI 1221
bridge, the i82365 driver requires ``p2cclk=1 irq_mode=0'' as well
as PCMCIA driver release 3.1.23 or later.

· With SCM Microsystems SBP series PCI card readers (which are also
being distributed with Lucent WaveLAN IEEE cards), and for the
Synchrotech PCM-CR-PC2IF and PCM-CR-PC2IR, it is necessary to
specify ``irq_mode=0'' for the i82365 module, to force use of PCI

· For the ActionTec PC 750 card reader, the i82365 driver requires a
``irq_list=0'' parameter, to indicate that ISA interrupts are

· The PLX Technologies PCI9052 (also sold as the Linksys WDT11) is
not a general purpose PCMCIA card reader at all: it is a PCI
interface card for use with certain wireless adapters, that makes
them look like ordinary PCI devices. These devices are not
