#
# Initialize or shutdown a PCMCIA SCSI adapter
#
# The first argument should be either 'start' or 'stop'.  The second
# argument is the base name for the device.
#
# The script passes an extended device address to 'scsi.opts' in the
# ADDRESS variable, to retrieve device-specific configuration options.
# The address format is "scheme,device,socket,channel,id,lun[,part]"
# where "scheme" is the PCMCIA configuration scheme; "device" is the
# SCSI device type (sd, sr, st, sg); "socket" is the socket number;
# "channel", "id", and "lun" are the SCSI device ID's; and "part" is,
# optionally, the partition number.
#
# The script first calls scsi.opts for the entire device.  If
# scsi.opts returns with the PARTS variable set, then this variable
# contains a list of partitions for which options should be read.
