Hello,

 

I have a lenovo g565 which has the ATI Mobility 4250 4200 (0x9712 id).I have successfully booted ML 10.8.5, SL 10.6.3 and 10.6.7 but the only problem is the graphics card.I am able to change resolution by installing dong's RadeonHD.kext (framebuffer).I want to patch the framebuffer personalities in the apple kexts (as seen in http://www.insanelymac.com/forum/topic/252061-mobility-radeon-hd-4650full-resolution-with-qe-ci-working-on-internal-lvds-screen/?do=findComment&comment=1655182 ) but this card,despite being based in the RV620 graphics processor ( "iago" framebuffer, compatible), it is integrated into the RS880m chipset (igp), and as result it uses part of the system ram to operate and it does not have separate VRAM.Because of that, I don't know which framebuffer to patch.I have successfully used radeondumptool and radeonhd in debug mode to capture the necessary logs for this operation (attachments).The ati.c file which is used in chameleon, uses "null" as the framebuffer for the RS880.

 

ati.c:

PS: Despite being 100% sure that me card is the 4250 (0x9712) ,the card's id in ati.c is 0x9715.Why? Edit: the gpu is the ati mobility 4200

 

Can anyone help me?

 

Thanks in advance
