ivik Posted November 16, 2010 Share Posted November 16, 2010 No. Driver should be rewriten to use bounce buffers like in linux and frebesd. You were lucky if that worked every time. Search forums, all people had problems with it. Why bugs you? Something doesn't work or some side effects? Does 10.6.4 IOne* work? Link to comment Share on other sites More sharing options...
gurde Posted November 16, 2010 Share Posted November 16, 2010 In 10.6.4 (x64) always worked, never had a problem with it. Worked flawlessly. Now in 10.6.5 (x64) the same thing doesn't work. Who could rewrite that driver? Link to comment Share on other sites More sharing options...
ivik Posted November 16, 2010 Share Posted November 16, 2010 I looked the code, but could't find any info on bounce buffer library for osx. You could also try to load IONet* from Extra. Delete all plugins inside and put BCM44* outside and build Extensions.mkext. This way it is loaded much soner and chances are way better to work. For me it worked about 99% of boots.

alexaffonso Posted November 17, 2010 Author Share Posted November 17, 2010 gurde, i'm having no side effects. I undesrtand what your talking about. I'm in the same situation. it worked very well at 10.6.4 and now it doesn't. I guess it's with some incompatibility of the driver with this new update, of course. With the solution gave by ivik, it's working without any problems. I think you should try it and see for yourself. And please, send me your VoodooSDHC if you can.
