# description: PCMCIA support is usually to support things like ethernet \
#              and modems in laptops.  It won't get started unless \
#              configured so it is safe to have it installed on machines \
#              that don't need it.

#
# Modified 2004.05.25 by CDRigby to address a problem with initialization
# of the yenta_socket driver.  To get the driver to properly recognize
# IRQs, the PCMCIA-relevant commands must be run as:
# /sbin/modprobe pcmcia_core
# /sbin/modprobe yenta_socket
# /sbin/modprobe yenta_socket pci=biosirq
#
# So, the if stanza is modified below to change
# /sbin/modprobe $PCIC $PCIC_OPTS >/dev/null 2>&1
# to
# (/sbin/modprobe $PCIC >/dev/null 2>&1 &&
# /sbin/modprobe $PCIC $PCIC_OPTS >/dev/null 2>&1)
# NOTE: this requires that /etc/sysconfig/pcmcia must be modified
# to include PCIC_OPTS="pci=biosirq"
#
# Don't ask me why - it would be better to fix the driver.  But, this
# krufty hack will do for now...
