I recently bought an Asus GeForce GTX 570 DirectCU II to put in my 2010 Mac Pro under Lion.
As said in this topic, I modified the NVDAGF100Hal.kext with my card id (which is 1086 not like classic 570s).
I even tried with ATY_init, but the Mac Pro never booted on Lion.
I can't even see it on the network, which proves that OS X didn't boot.
Windows boots fine.
Any idea if I made something wrong ?
Or if it might change with 10.7.2 beta ?
