I would like to share my experience about ATI Radeon HD 6470M on Asus A42JZ Notebook. Part 1: Current Status & Information about my best configuration What I uses: - with 6470M id added - ATI Kext from MBP2011 10.6.7 with patched Ipomoea personality (using and method Current Status: LVDS: Not working, blank/black screen with backlight turn on (can turn off/on using keyboard “Fn”).

The screen can be used in VESA mode (1024x768x32) using GraphicsEnabler=No. 10^11 prefix. HDMI: Working, Correct FullHD 1080p resolution with QE/CI, HDMI-audio not working.

6470m

Oct 25, 2011  Re: Radeon 6470m Project Count me in, guys! I'm pretty sure that chameleon still has the wrong device id inside for the 6490M. Then again, after adding my device id it still showed up as unsupported on the bootloader. Dec 14, 2013 - On at 12:25 PM, pippox0 said: Hi, i have a Radeon hd 6450 and doesn't works. Which Kext do you have used for your 6470??

VGA: Working, Correct resolution 1440x900 using SwtichResX. Remarks: - QE/CI will work only when HDMI is pluged in before OS X boot. If plug HDMI after OS X booted, screen still working but no QE/CI. - QE/CI tested feature: transparent topbar, ripple effect in dashboard, Adobe flash worked.

End of Part 1 ======================================================================= Part 2: Testing on Transmission/Encoder (Not working yet, just for reference and discussion purpose) In this section, I'll try to get LVDS working by focus on TransmissionID/EncoderID. I assume that my ATI HD 6470M is DCE 4.0 compatible because my HDMI port exactly matched this spec.

From output, It tells me that LVDS port is using UNIPHY0. So there are possible 3 values to be tested: 0x1000, 0x0000, 0x2001. * DCE 4.0 * - 3 DIG transmitter blocks UNPHY0/1/2 (links A and B).

* Supports up to 6 digital outputs * - 6 DIG encoder blocks. * - DIG to PHY mapping is hardcoded * DIG1 drives UNIPHY0 link A, A+B 0x1000 0x0000 * DIG2 drives UNIPHY0 link B 0x2001 * DIG3 drives UNIPHY1 link A, A+B * DIG4 drives UNIPHY1 link B 0x2103 HDMI * DIG5 drives UNIPHY2 link A, A+B * DIG6 drives UNIPHY2 link B.
