macrovers Posted July 2, 2013 Share Posted July 2, 2013 Hi everybody, i have installed iAtKOS L2 ( lion 10.7.2 11c74 ) on my HP Pavilion a6230in. Issue > GPU not detected and display resolution only 1024x720 ( mine is a HPw1907 1440x900 ) My Specs: Intel Pentium ® Dual CPU E2140 @ 1.60 GHZ. ASUS P5LP-LE 2.5 GB RAM Network Card - Intel Pro 100 VE GPU - ASUS GTS450 1 GB DDR5 The issue is that my mackintosh doesn't recognize my GPU. When i go to > About this mac > System Report > Graphics and Display I get this >> Display: Type: GPU Bus: PCIe PCIe Lane Width: x16 VRAM (Total): 3 MB Vendor: NVIDIA (0x10de) Device ID: 0x1245 Revision ID: 0x00a1 Displays: Display: Resolution: 1024 x 768 Pixel Depth: 32-Bit Color (ARGB8888) Main Display: Yes Mirror: Off Online: Yes The options i ticked during install are : Boot loader > Chameleon 2.1 Boot loader Options > Graphics Enabler Built in Ethernet Patches > FakeSMC Disabler RTC>RTC Ev0Reboot IOPCIFamily Drivers > Main hardware > SATA/IDE > ACHI SATA Sound > VoodooHDA > 2.7.2 USB > USB Hardware Sensors > CPU Motherboard nVIDIA VGA Cards PS/2 VGA > nVidia > GF100 Network > I didn't select anything, after installation i added AppleIntel8255x.kext to S/L/E ( with modified value in info.Plist ) using kext wizard. So anybody who have installed GTS450 or any fermi cards, kindly have a look and suggest me to figure this out. Link to comment Share on other sites More sharing options...

macrovers Posted July 2, 2013 Author Share Posted July 2, 2013 Thank you artur, i followed ur steps, added my DevID and Ven ID in NVDAResman.kext and NVDAGF100Hal.kext. My GPU is detected and i am now running full resolution. Again a small issue, Earlier i got audio working by using VoodooHDA.kext (2.7.2),the onboard ICH7 HD Audio was woking. But now no Audio, i have got the Dev ID and Ven ID of my Geforce HD Audio, but i don't know where to add those values. Link to comment Share on other sites More sharing options...
