 <p><h2>Changes done for each driverversion:</h2></p>
+<p><h1>head (SVN 0.81, 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.

 <p><h1>nv_driver 0.80 (Rudolf)</h1></p>
 <ul>
 <li>Improved 3D speed related initialisation programming for NV11 and NV15: NV11 just gained 44% rendering speed, NV15 gained 21% speed. The GeForce2Ti (NV15) is the new winner: Quake 2 timedemo 1 runs at 28.3fps in 1024x768x32 mode @ 75Hz refreshrate (P4 2.8Ghz, fsb 533Mhz, AGP4x), while on the GeForce4MX (NV18) it keeps running at 26.3fps. The GeForce2MX (NV11) now runs at 18.9fps.
