## Changes done for each driverversion:

# head (0.06-16, Rudolf)

- Updated modelist to include one more suggested mode for 800x600 resolution: Done by Andrew Bachmann;
- CRTC timing restriction checking updated: Modelists exported adhere to every cards max. CRTC capability now: the oldest cards support upto and including 1024x1000, while the newest cards support upto and including 1280x1024 resolution;
- Kernel driver now signals abort on not being able to setup the INT routine instead of letting the machine freeze during accelerant initialisation;
- BWindowScreen R3-style function update for acceleration (once setup) and page flipping/virtualscreens in apps ('Allegro' update): fixed cloning accelerants;
- Updated acceleration engine management code;
- Added full 2D acceleration for NM2070, NM2097 and NM2160 cards (the others will be added later);
- Updated acceleration for massive speedup compared to Be driver (now running at approx 200-2000% depending on use!);
- Fixed acceleration on rectangle fills and inverts: nolonger executing zero-width commands (which the app_server gives to the driver sometimes!) so no more big-time distortion stripes onscreen! (the Be driver does exhibit this fault BTW);
- Updated hardware cursor to be placed elsewhere in cardRAM (acc engine requirement); distorted mousepointers could be fixed by this also on some cards outthere;
- Updated workspace virtualsize restrictions for accelerated modes. Confirmed that the MagicGraph series (pre NM2200) engines can do upto and including 1600x1024 resolution except NM2070 which can do upto and including 1024x1024. Assuming MagicMedia series (NM2200 and later) can do upto and including 1600x2048 for now. Modes above these resolutions are unaccelerated;
- Removed register area cloning bug in accelerant that prevented it from working with NM2070, NM2090 and NM2093 cards at all!
- Added various fixes to get Dell Latitude XPi (NM2070) working on it's panel, probably fixes various faults on other cards as well;
- Updated pixelPLL restrictions for NM2070 so external output refresh is OK;
- Added fixed sync polarity programming if flatpanel in use: needed to make sure centering actually works;
- Disabling centering if external only monitor mode is active: fixes some trouble on NM2070 and maybe others;
- Added panel modeline programming for NM2070 cards: fixes hardcursor trouble on panel;
- Added pixelprecise panning for virtualscreens in all modes;
- Added full DPMS support.

Note:
Acceleration engine benchmarked and tested for errors with BeRoMeter V1.2.6.

# nm_driver 0.05 (Rudolf)

- Prevent system or video freeze on dragging files or so in tracker windows;
- BWindowScreen / Sync_to_retrace fix: prevent apps from crashing on endless waiting for retrace. Wait_for_retrace is temporary disabled now until it's actually implemented;
- Sync polarity setup now actually works (external monitor only mode);
- Power-up register unlocking narrowed down to overlay engine only. This should fix the screen rubbish trouble most users had with V0.04 which did not exist for them on V0.03.

# nm_driver 0.04 (Rudolf)

- included hardware overlay for the B_YCbCr422 (FourCC: YUY2) colorspace;
- added CRTC registers unlock command on startup.

# nm_driver 0.03 (Rudolf)

- virtual screens / BWindowScreen support including panning/scrolling;
- colorspace selection;
- colorpalette setup;
- refreshrate selection in external (CRT only) mode;
- resolution selection;
- hardcursor support;
- preliminary LCD panel centering support;
- you can switch between panel and the external monitor via the special key on the laptop KB. Also the driver respects the output preselected in the BIOS. Note that the NeoMagic BIOS does the output device switch: the driver may not work correctly in all settings yet.

# Still todo:

- fix for trouble with booting into modes above 800x600 resolution on some cards (please report this behaviour!);
- 2D acceleration (in progress);
- MagicMedia series overlay update: still contains errors.
