<p><h2>Changes done for each driverversion:</h2></p>
<p><h1>head (Haiku repository 1.11, Rudolf)</h1></p>
<ul>
<li>Fixed driver trouble on several Geforce 6000-6200 cards and maybe even more where the refreshrate was not properly calculated causing things like only displaying a part of the screen, a wobbly screen, no screen at all or just displaying at a too low rate. In cases where the GPU and/or RAM PLL is programmed on cards (depending on the nvidia.settings file) this might also solve random 'noise' or flickering across the entire screen(s). It turns out some newer supported cards outthere (notably Nforce 4 and 4xx types) use a new crystal frequency base (25 Mhz) for the GPU chip which was not yet detected by the driver.
</ul>
<p><h1>head (Haiku repository 1.10, Rudolf)</h1></p>
<ul>
<li>Fixed driver assuming enabling AGP mode succeeded on some occasions if it did not block it itself. Blocking AGP mode completely via the AGP busmanager (option 'block_agp') resulted in a crashing acceleration engine because it was setup for AGP transfers instead of using PCI transfers. Error was solved with help from user kraton.
