I installed JaS 10.4.8 and then upgraded to koolkal 10.4.10 as instructed in this guide
http://forum.insanelymac.com/index.php?showtopic=58475
I followed that guide and everytime I install the Natit DioboliK installer my system reboots and gets vertical white and black lines and then goes to a black screen. I have an ATI x1600 Mobility device ID 0x71c5 with 256mb ram.
How can I get this card to work, and also how can I recover from a bad video driver install that turns my screen black? How is it possible to boot into a fail-safe terminal and then how would I revert a driver install?
