ZIDEFS updates
--------------

<1.00 (last version was 0.90)

removed

1.00

- 'Resync' version : internally revamped, updated for Risc PC.
- The filing system name is now ZIDEFS instead of IDEFS.
- Now uses a different (and official) filing system number and SWI chunk.
- Updated to run on Risc PCs and RISC OS versions 3.5 through 4.03+.
- Full support added for 'large' (>512 MB) drives, up to 256 GB.
- Makes use of harddisc's LBA (Logical Block Addressing) if available.
- Filer's drive icons now show the disc name, and resize when renamed.
- HFormPatch updated to work on not just one but a range of !HForm versions.
- Bug fixed : the 'timeout' error code returned was not correct.
- Bug fixed : transfer address range check did not fault starting inside ROM
  but ending outside ROM (when writing to harddisc).

1.01

- The 'module box' (the container for the LZW compressed ZIDEFS and ZIDEFSFiler
  modules) now kills itself by returning an initialisation error rather than
  calling OS_Module 4 via a callback.
- The name of the module box is no longer generic but ZIDEFS specific, in this
  case ZIDEFSBox (to avoid boot time clashes with other module boxes in ROMs,
  i.e. ViewFinder's).
- The ZIDEFiler module is now called ZIDEFSFiler (for consistency).

1.02

- Internal maintenance release (only minor internal changes).

1.10

- An alternative ROM file now presents ZIDEFS as 'IDEFS' instead of 'ZIDEFS'.
  This may be useful if the ICS interface + filing system is to run a disc that
  was previously run by another interface + filing system called IDEFS (paths
  in files on the disc may then have 'IDEFS' hard-wired, and this is usually
  hard to change to 'ZIDEFS' by hand without re-installing everything on it).
  Similarly for 'ADFS'.
