Can't help a bit with the PCMCIA card but I think that the problem with mount 
may be with finding the device on which the MS file system resides.  If this 
is TNG, you can start the control center using the panel monitor icon that is 
half covered with green.  Look in information, block devices and it should 
show you all the devices that are there.  If you are doing this as root, you 
can mount and unmount from there also.
