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

                                  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.

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.
