marcvaz Posted July 17, 2011 Share Posted July 17, 2011 Hello I have an Intel Board DG41RQ which have internal graphic card i think GMA4500 controller, when i installed Lion GM on it it got stuck at PCI configuration begin. After a lot of research and many tries i found out that my Radeon HD4850 is giving problem. So I removed the card from my system and Voilla the leopard installation starts. I have another system Intel DP35DP which doesn't have any onboard graphic card on that system i tried to install Lion and it worked directly with Radeon HD4850. So I am confused here. It seems that onboard graphic card and Radeon HD4850 is clashing somehow. Does anyone have a solution to this? Link to comment Share on other sites More sharing options...
