Changes done for each driverversion:

head: nv_driver 0.09-1, (Rudolf)

• Fixed NV11 trouble with repeating screen(s) on the right side of the monitor.

nv_driver 0.08, (Rudolf)

• Fixed GeForceFX 5600 and FX 5700 monitor 'refresh out of range' / shutoff fault. nVidia changed the pixelPLL for the NV31 and NV36;
• Fixed acceleration engine restrictions code to adhere to GeForceFX 5600 restrictions: those are still NV20 style for this card;
• Fixed overlay scaling restriction code to adhere to GeForceFX 5600 restrictions: engine is still the NV10/NV20 one, so it can downscale to 1/8 of the picture size;
• 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 and page flipping/virtualscreens in apps ('Allegro' update): fixed cloning accelerants;
• Now only programming options head select register on dualhead cards. This fixes driver hanging on integrated GeForce2 cards (ID 0x01a0), and maybe also on some other cards;
• Expanded modelist to include suggested modes above 1600x1200 upto 2048x1536 resolution (if a card supports them): Done by Andrew Bachmann;
• Added card recognition for GeForceFX 5700, FX 5950 and some other (older) cards;
• Added 256Mb RAM detection;
• Improved startup code: this should (could) fix random trouble on some cards like for instance hardcursor trouble on especially laptops;
• Added dualhead support (use Mark Watson's 'Dualhead Setup' from BeBits for now);
• Updated mode granularity and max virtual size checking/limiting;
• Added dualhead support for 8- and 15bit colordepths;
• Fixed move_display distortions in virtualscreens especially visible in 8-bit colordepth (for both heads);
• Added 'overlay follows head' for dualhead stretch and switch modes: if more than half the overlay output window is on a screen, that screen gets the overlay output;
• Added dualhead switch mode (except for NV11 cards as they do not have output connector switching capability);
• Added monitor presence detection for both monitor output connectors on dualhead cards (analog type signals only);
• Added 'output follows monitor' for all modes: it does not matter on which connector you connect your monitor, the output will go there after setting a mode; like the card's BIOS does (except for NV11 cards as they do not have output connector switching capability).

nv_driver 0.07 (Rudolf)

• Added card recognition for some Nvidia GeForce4 Ti 4600 cards (ID 0x0252);
• GeForce overlay activation updated: hardware should respond to the first request instead of to the second ('stampTV' update);
• Included B_YCbCr422 hardware overlay for TNT 1/2 class cards (pre NV10 architecture).

nv_driver 0.06 (Rudolf)

• Added full 2D acceleration for TNT1 - GeForce FX cards;
• Added card recognition for GeForce FX Go and some older laptop cards;
• Implemented retrace synchronisation (INT routine);
• Geforce overlay updated: turned off ints explicitly, corrected upscaling restriction to be 8x, small speed improvement;
• Vertical timing updated: missed a register on all GeForce cards, missed another register on older cards;
• Register unlocking updated: missed a register on all supported cards.

nv_driver 0.05 (Rudolf)

• Update on cursor move routine: pointer will nolonger accept illegal left-top positions. As a result it will nolonger vanish on some cards;
• Fixed hardware overlay on GeForce4 MX and Go series cards: disabled the embedded MPEG2 decoder engine which exist on these cards only;
• Fixed driver to adhere to the downscaling limitations of the new overlay engine existing in the GeForceFX series cards.

nv_driver 0.04 (Rudolf)

• New cursor_move sync_to_retrace for all supported cards: now all display distortions should be gone (GeForce4 for example);
• Added hardware overlay support for the entire GeForce series cards;
• Now powering up all card function blocks: dualhead cards should now switch to the connected head (by it's BIOS) instead of hanging the system on boot (tested on a dualhead GeForce4 with a DVI and a VGA connector).

nv_driver 0.03 (Rudolf)

• Prevent system or video freeze on dragging files or so in tracker windows;
• Pre NV10 cursor sync_to_retrace: no more distortions in cursor bitmaps on moving it;
• Cursor bitmapadress setup modification for laptops: The cursor should be visible now also on 'Go' type of cards;
• 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.

nv_driver 0.02 (Rudolf)

• hardcursor support;
• virtual screens / BWindowScreen support including panning/scrolling;
• colorspace selection;
• colorpalette setup;
• refreshrate selection;
• 85 cards of 4 brands are detected now: These are all TNT1 - GeForce FX5900 Ultra cards as far as I know. Hopefully all those cards will actually work OK with the driver;
• DPMS support;
• resolution selection (CRTC setup);
• switch to 'enhanced mode' included: VESA is gone now!
• cardspecs are setup (faked PINS);
• several small fixes done to get the driver working correctly on all four of my cards: PCI TNT1, AGP TNT1, AGP TNT2 and AGP GeForce2MX400.

Still todo:

• Add support for internal display panels (laptops);
• TVout support;
• Partial card coldstart: setup RAM and CORE speeds (if possible).
