The PMA under the Archos firmware uses a cramfs filesystem created on boot from an image file stored on the hard drive.
The hard disk drive uses FAT32 and is mounted at /media/
You could find cramfs part in the firmware of PMA by searching the CRAMFS magic number (0x28cd3d45). To do, open firmware in a hexadecimal editor as khexedit (linux) and search hexa 453dcd28. It represents the start of cramfs part.
