GR8NET ROM BIOS release notes

Date: 19 Feb 2020
Build: 20200219
- exFAT file system support;
- extra arguments for NETPLAYWAV;

Date: 28 Oct 2019
Build: 20191025
- Mapper mode 7 NETSETMAP/NETTGTMAP
  argument MRPD is now switching
  sample RAM on rather than disabled

Date: 25 Dec 2017
Build: 20171225
Previous release: 20171118

  in MPEG stream, displaying it onto
  the screen;

  8 mode (with Nextor available in
  subslot 2, and subslot 3 being empty);
- NETTELNET command was removed, command
  NETTERM put instead.

Date: 09 May 2017
Build: 20170509
Previous release: 20170426
- Redesigned built-in disk-ROM so that
  most .DSK images are operational with
  GR8NET now;
- extended NETVER command info reporting;
- added mappers 9-14;
- changed GR8NET identification through
  index I/O port - instead of just 'G'
  now application reads "GR8N" followed
  by the year (word), month (byte) and
  day (byte) of the GR8NET engine build;
- added NETGETMAP command;
- added third argument to NETSETMAP
  command to disable mapped RAM in
  mappers 8-14;
- expanded set of arguments in brackets
  {} for browser's ROM file identification
  to 3.

Date: 26 Apr 2017
Build: 20170426
Previous release: 20170321
- Added MP3 format support for media
  player;
- developed fix for MP3 cartridge
  in its ATMega firmware to be used
  with GR8NET for MP3 playback.

Date: 21 Mar 2017
Build: 20170321
Previous release:20170316
- Added two commands: NETSYSINFO and
  NETVARUDTO.

Date: 13 Feb 2017
Build: 20170213
Previous release: 20170203
- Changed NETOPLL to two commands
  NETSETOPLL and NETGETOPLL;
- rewrote initialization sequence to
  include initialization and
  reservation of the Y8950 sample RAM.

Date: 22 Jan 2017
Build: 20170122
Previous release: 20161229
- Implemented browsing of the disk image
  on the startup (F2 key), forceful
  image reload (F1 key);
- added host name (DHCP option 12) as
  "gr8net-xxxxxxxxxxxx" where x is
  adater's MAC address
- added MSC-MUSIC ROM is mapper mode 8
- added OPLL statement

Date: 15 Apr 2016
Changes/enhancements:
- Significantly increased speed of
  CALLNETBTOV command putting data
  into VRAM;
- Now CALLNETBTOV accepts source data
  logical page # in bits 8:1 of its
  first argument, thus developer has
  option to keep multiple images
  in GR8NET memory;
- Fixed bug in PLAYWAV, it was not
  playing remainder of the buffer;
- Added two more arguments to
  NETBLOAD identifying starting
  logical page and address to load
  data.

Date: 06 Feb 2016
Build: 20150206 (v.0.3)
Previous release: 20151223
GR8NET engine update required: No, but
  recommended (to v.0.3)
**Offline update required**
Changes/enhancements:
- DOS1 integration, driver supporting
  disk images as RAM-disk in GR8NET
  RAM;
- CALLDSK family introduction;
- CALLNETSNDVOL command to set audio
  volumes, stored in config page
  (saveable by NETSAVE command);
- Changed firmware direct call addresses:
  now call points are located at the end
  of the ROM page 80h, so as GR8NET ROM
  signature;
GR8NET engine changes/enhancements:
- Improved SD-card handling, increased
  data communication timeout;
- Redesigned SCC implementation
  including 4-point moving average
  filter @ high frequencies.

Date: 23 Dec 2015
Build: 20151223
Previous release: 20151202
GR8NET engine update required: No
Changes/enhancements:
- New command CALLNETBTOV;
- Improved dumping: NETDUMP now dumps
  with character images in order to
  recognize text, bytes are separated
  by the spaces;
- Added NETCODE command (for NETBLOAD,
  NETBROWSE, NETDHCP AND NETSETHOST)
  because just "Device I/O error" is
  completely uninformative and we need
  advanced diagnostic codes;
- Changed format of the NETBLOAD
  command: now first optional argument
  is URI string, second is run
  flag (0-2).
Bug fixes:
- no initialization of the URI structure
  within NETPLAYWAV statement handler.
  Amended with copying of default URI
  structure before parsing input URI string;
- incorrect bank 3 page change in the
  socket closing routine used for device
  CLOSE operator;
- NETDUMP used wrong switching mechanism
  throughout banks, changed to bank 1 only
  and to full page range, also corrected
  helper text;
- PARURI routine had a bug when path part
  of the structure is not terminated
  with 0 (EOL);
- Was performing connection close without
  disconnection process, this causes some
  servers going crazy. Changed to DISCON
  and only then CLOSE basing on the W5100
  status register;
- NETBLOAD was treating BSAVED images as
  executables, and was trying to move
  them to data locations (e.g. 0-DFFF)
  causing machine crash. Changed NETBLOAD
  behavior - now to have binary moved
  NETBLOAD needs argument of (1), and
  to be moved _and_ executed argument (2).
  NETBROWSE's space key hit assumes
  argument (0), enter key hit assumes (2);
- removed usage of W5100 socket interrupt
  register as it does not reflect current
  status of the connection. Now basing
  solely on status register;
- revised BASIC device support as it was
  frequently giving Device I/O errors -
  now it checks for buffer once more after
  checking for TCP connection termination.
  I also extended NETDIAG diagnostic
  messages onto the device OPEN execution;
- corrected bug in PARURI when it is
  passed empty string it hung. Now it
  checks for empty string and returns
  doing nothing with CY set;
- fixed bug in NETBROWSE when at some
  condition I did not return to primary
  register set in the link highlighting
  routine and highlighting was displayed
  incorrectly.
