Hey Ray, or anyone else

Do you know how to access a fat32 file system from
linux on a dual boot machine? Also I have a PCMCIA
ata memory card that I would also like to access from
Linux. If I go to the hardware info icon it shows up as
hde1 but there is nothing under the mnt directory for
either that or the FAT32 file system.
