With proper drivers configured, the kernel will detect the CF drive's partitions. You will use "mount" command to map the file system on the CF drive to a dir. Then you can access CF's data under that mount dir.

eg, you have FAT16 formatted the partition 1 of the CF drive, it will become /dev/hda1 .

Then "mount -t vfat /dev/hda1 /mnt" will map the CF drive to dir /mnt . After you have finished the access, "umount /mnt" will unmap the CF drive.
