demil Posted February 28, 2013 Share Posted February 28, 2013 These are the main specifications: Intel Core i3 2,4 GHz 370M Chipset Intel HM55 Express Front side bus 1.066 MHz RAM: 4GB DDR3 1066Mhz Graphic Card: ATI Radeon HD 6370M 1GB Hard Disk: 320GB SATA I tried using iATKOS L2 (I know it's Lion, but I wanted to install it and then make a bootable USB drive using #####). The problem is that, when I try to install it, I get stuck at this point: [ PCI Configuration Begin ] I tried these boot flags: npci=0x2000 -v -f -x What do you suggest to install Mountain Lion on this laptop? Thank you! Link to comment Share on other sites More sharing options...
slayer2333 Posted February 28, 2013 Share Posted February 28, 2013 Well i think that you need to use PCIRootUID=1 instead since you have an ATI graphic card, give it a shot. Link to comment Share on other sites More sharing options...
