*
* Note:
* - In order for detection to work, jumper 3 must be set.
- * - Drive A and B use a proprietary FTL from General Software which isn't
- * supported as of yet so standard drives can't be mounted; you can create
- * your own (e.g. jffs) file system.
- * - If you have created your own jffs file system and the bios overwrites
+ * - Drive A and B use the resident flash disk (RFD) flash translation layer.
+ * - If you have created your own jffs file system and the bios overwrites
* it during boot, try disabling Drive A: and B: in the boot order.
