Changes

Here is the list of the main changes between versions of UniDOS and DOS nodes.

• UniDOS: fixed |COPY to work on binary files with unexpected non zero value for header field “left bytes” (usually those files can not be created on CPC, but some tools on PC do generate such binary headers).

• UniDOS: reworked activation and deactivation system (removed RSX |DOS and disabled |DISC and |TAPEin favor of a new RSX |AMSDOS).
• UniDOS: changed keys to be pressed to reinitialize the non volatile memory (CONTROL+SHIFT instead of CONTROL alone).
• UniDOS: improved |NODE RSX.
• UniDOS: added time and date handling as well as a RSX |LIST which displays last modification date of files and directories.
• UniDOS: improved initialization scheme of DOS nodes.
• UniDOS: added support for Basic and binary protected files.
• UniDOS: added new BIOS routines cmd_examine and cmd_examine_next to get détaille information about files and directories.
• UniDOS: added a new BIOS routine cmd_is_active_dosnode to probe DOS nodes status.
• UniDOS: added new DOS node access routines related to real time clock management.
• UniDOS: added a mechanism to allow access to RSX of all DOS nodes (even if they are extension ROMs ou background ROMs beyond slot 15).
• UniDOS: improved overall AMSDOS compatibility
• UniDOS: optimized speed access to floppy disc drives.
• UniTools node: added a RSX |HELP to list installed ROM and |WHERE to locate RSX.
• UniTools node: added a mechanism to deactivate developper tool ROMs with the related RSX |DEVTOOLS.ON and |DEVTOOLS.OFF.
• Nova node: added real time clock management (both read and write).
• M4 node: added real time clock management (read only).
• M4 node: turned into an extension ROM instead of a background one.
• All nodes: added last modification time and date handling for files and directories.

• UniDOS: Added a |CAT RSX which list directories first and colored them.
• UniDOS: Optimized cold boot detection routine.
• UniDOS: Added a flag register at DOS nodes initialization.
• UniDOS: Fixed a bug in soft end emulation for files smaller than 128 bytes.
• UniTools node: New node which supports automatic startup on bootable devices and provides an improved ZERO: drive.
• Zero node: Removed node in favor of UniTools.
• Albireo node: Added support for a second Albireo plugged at the same time.
• All nodes: Better drives built-in description.

• UniDOS: Fixed BIOS routines cmd_cas_out_seek and cmd_cas_out_write which did not work as expected.
• UniDOS: Activated ASCII soft end of file emulation everytime and removed related BIOS routine cmd_emulate_soft_eof.
• UniDOS: Fixed a bug which made BIOS routines cmd_enabled_sort_dir_first and cmd_disabled_directory to alter both options at the same time.
• UniDOS: Fixed an AMSDOS compatibilté issue when file extension is prefixed with spaces.
• UniDOS: Removed ability for a DOS node to modify default assignation of logical drives.
• M4 node: Allowed execution of cartridges on Amstrad CPC and not only on Amstrad Plus.
• All nodes: Removed code related to modification of default assignation of logical drives.

• UniDOS: Fixed CAS OUT CLOSE to allow creation of files even if CAS OUT CHAR was never called after CAS OUT OPEN (better AMSDOS compatility).
• M4 node : Added physical drive FTP: and the related RSX |FTP (please read the M4 node documentation to know about the applied restrictions).

• UniDOS: The “new API” flag from BIOS routine cmd_device_info is now set automatically (it do not rely on DOS nodes DOSNode_GetStatus routine any more).
• UniDOS: Fixed BIOS routine cmd_device_list to return with Carry=1 in case of success.
• UniDOS: Added a BIOS routine cmd_enabled_sort_dir_first to request CAS_CATALOG to sort directories prior to files (by default directories and files are mixed for compatibility reason because of some softwares relying on a strict alphabetic order).

• UniDOS: Fixed a bug with ROM overlay during du CAS_IN_CHAR.
• UniDOS: Fixed a bug in BIOS routine cmd_cas_in_read when less than &80 bytes were read from an ASCII file.
• UniDOS: Modfified the behavior of the BIOS routine cmd_cas_in_read in case of binary files (file headers is not skipped anymore, which makes cmd_cas_in_read usage symetrical to cmd_cas_in_write to provide a more generic handling of all file types).
• FatFs node: Improved intialization sequence when Nova is detected (more robust in case of wrong ROMs installation and more system friendly regarding interrupts).
• FatFs node: Modified cross-ROM call routine to be more system friendly.

• UniDOS: Fixed error handling in case a DOS node fails to initiate a catalog.

• UniDOS: Improved error handling in case of routines which are not supported by DOS nodes.
• UniDOS: Fixed minor issue in the internal routine managing iteration over files (without any impact for existing nodes).
• Nœud M4: Initial version.

• UniDOS: Added Hackit compatibility.
• UniDOS: Added error report when |COPY targets a non existing directory.
• FatFs node: Removed “disk cache” mode (it was too slow and prevented some future improvements).
• FatFs node: Added automatic support to the Nova when detected (in its presence FatFs node do not use main memoy at all).
• FatFs node: Moved temporary working buffers to provide a better compatibility (hacks which are initializing disc ROM at addresses conflicting with Basic now also work with FatFs node).

• UniDOS: Fixed double sided and 80 tracks support from ParaDOS.
• UniDOS: Fixed aregression when failing to close fils handled by AMSDOS/ParaDOS ROM.

• UniDOS: Added RSX |LOAD, |SAVE and |SAVEA similar to the ones which were provided by ROMs from Arnor Ltd.
• UniDOS: Internal simplifications.
• Nœud Nova  Initial version.

• UniDOS: |REN not provides the ability to move files (and directories) from a direcotry to another (when the related physical drive is compatible).
• UniDOS: Added new error codes related to renaming.
• Albireo and FatFs nodes: Upgraded DOSNode_Rename routine.

• UniDOS: Changed file type for symbolic links to avoid a conflict with text documents of Protext.
  If you had symbolic links created by an UniDOS previous version, you will have to recreate them, old ones will not work anymore.
• UniDOS: Fixed a regression non volatile memory handling when |DISC was used.
• UniDOS: Fixed a regression with unwanted assignation mismatch between drives A: and B:.

• UniDOS: Added TAPE: drive which supports tapes.
• UniDOS: Added RSX |FORMAT and |NODE.
• UniDOS: Fixed internal memory handling.
• Albireo node: Optimisations.
• FatFs node: Initial version.

• UniDOS and DOS nodes: Initial version.
