Two filesystems are currently available in RTEMS - IMFS and DOSFS. IMFS -
is in-memory filesystem and hence is not appropriate for you. DOSFS is
MSDOS-like(and compatible:) filesystem and available since rtems snapshot
at 01 of March.

Also currently noboby has announced any driver for IDE disks for RTEMS,
but floppy driver was announced.

As I know - nobody.
