<li>If you want BScreen 'Sync_to_Retrace' capability make sure you enabled 'assign IRQ to VGA card' in your system BIOS (if available);
<li>If the driver still seems to create 'random' trouble make sure you have a fully functional VGA BIOS, or system BIOS for embedded cards (check for updates on the manufacturor's site). Make sure you mail me if you still have trouble but also if this version fixed that!
<li>If on a laptop the internal panel doesn't work when you connect an external monitor, make sure you set 'output device selection' to 'internal' (instead of 'auto') in the system BIOS if it has such an option. If you have this symptom on a normal card, or on a laptop without that BIOS option then you are probably out of luck for dualhead support;

Secondary analog monitor detection doesn't work and we can't control very well to which connector the card's output gets routed (lack of specs). This means you might have to experiment a bit with the way you connect your monitor to the card. A single analog or DVI screen should work OK, and two analog screens should be OK as well.

You can select one of two methods for (2D) acceleration here: PIO mode and DMA mode. DMA mode works 4-10 times as fast as PIO mode on modern CPU's (beyond 2Ghz or so), and should still be 2-3 times as fast as PIO mode on slower CPU's (below 500Mhz).
<ul>
<li><strong>false:</strong><br>
If the default setting does not work as expected, you can try falling back to PIO mode acceleration. Note however that PIO mode is currently not working on NV40 and higher GPU's (GeForce 6200, 6600 and 6800 like types). Also, chances are that this method of acceleration will be removed in future driverversions (so be sure to let me know if you are having trouble with DMA mode!).

<strong>dma_acc true</strong> enables DMA cmd fetching by the GPU for (2D) acceleration instead of using the old PIO method (which directly programs acceleration commands inside the GPU). The DMA method works (much) faster than PIO mode depending on system CPU speed. Also the DMA method is the only method that works on NV40 and higher GPU's (GeForce 6200, 6600 and 6800 like types) currently.

<li>Added capability to driver to run without an INT assigned. Driver will now automatically disable the 'Sync_to_Retrace' function if no INT was assigned instead of not loading/running at all;
<li>Fixed PLL reference recognition (used for refreshrate calculations) and dualhead detection for a number of 'newer' cards: most notably for a lot of GeForce 6200 types! Code is rewritten so it's much less breakable when new cards are added to the supported list in the future;

<li>Added custom modeflag for users to be able to select TVout head on a 'per mode' basis. The Dualhead Setup preference panel needs to be updated (to a version newer than 0.03a) to correctly issue this flag;
<li>Added rudimentary NV11 CRTC2 FIFO watermark/burst-size programming to remove/minimize vertical distortion stripes occuring on some cards due to data fetching errors (because of limited bandwidth);
<li>Modified NV05M64 (TNT2-M64) watermark/burst-size programming to be executed independant of coldstart feature;
<li>Updated acceleration engine DMA-mode initialisation code (in progress): This should fix trouble on some newer cards with acceleration, and adds NV47 (G70) acceleration support.
