JoachimCraeye Posted February 2, 2016 Share Posted February 2, 2016 You need to replace Device (PEGP) in your DSDT with this code for the above kexts to work. Change "VRAM,totalsize", to 0x00, 0x00, 0x00, 0x40 if you have 1 GB VRAM.But first you need to convert your VBIOS.rom to DSDT code with rom_dsdt_converter.exe (download here) and paste it in "ATY,bin_image", like this:========================================================================== "AAPL,slot-name", Buffer (0x0C)\n { "PCIe Slot-1" }, "ATY,bin_image", <= Look for this line in the code for Device(PEGP) below Buffer () <= leave Buffer empty! { PASTE YOUR CONVERTED VBIOS HERE IN ON ONE LINE }, "device_type", Buffer (0x12) { "ATY,IpomoeaParent" },========================================================================== You can download this PEGP2_6650M_2GB.txt.zip patch for the PEGP and apply it with DSDTParser.jar but you still need to manualy insert the converted VBIOS for the 6650M to be recognized by the OS and of course Device (HDAU) for HDMI Audio. Place it just above Device (PEGP). You also need to apply the DTGP patch before compiling your DSDT. This is how it should be shown in IORegistryExplorer Screen Shot 2013-06-25 at 12.35.53.png Device (HDAU) { Name (_ADR, One) Method (_DSM, 4, NotSerialized) { Store (Package (0x02) { "hda-gfx", Buffer (0x0A) { "onboard-1" } }, Local0) DTGP (Arg0, Arg1, Arg2, Arg3, RefOf (Local0)) Return (Local0) } } Device (PEGP) { Name (_ADR, Zero) Name (_PRW, Package (0x02) { 0x09, 0x04 }) Method (_DSM, 4, NotSerialized) { Store (Package (0x2E) { "@0,compatible", Buffer (0x0C) { "ATY,Ipomoea" }, "@0,device_type", Buffer (0x08) { "display" }, "@0,display-dual-link", Buffer (0x04) { 0x01, 0x00, 0x00, 0x00 }, "@0,display-type", Buffer (0x04) { "LCD" }, "@0,name", Buffer (0x0C) { "ATY,Ipomoea" }, "@1,compatible", Buffer (0x0C) { "ATY,Ipomoea" }, "@1,device_type", Buffer (0x08) { "display" }, "@1,connector-type", Buffer (0x04) { 0x00, 0x08, 0x00, 0x00 }, "@1,display-type", Buffer (0x05) { "NONE" }, "@1,name", Buffer (0x0C) { "ATY,Ipomoea" }, "@2,compatible", Buffer (0x0C) { "ATY,Ipomoea" }, "@2,device_type", Buffer (0x08) { "display" }, "@2,connector-type", Buffer (0x04) { 0x10, 0x00, 0x00, 0x00 }, "@2,display-type", Buffer (0x05) { "NONE" }, "@2,name", Buffer (0x0C) { "ATY,Ipomoea" }, "AAPL00,DualLink", Buffer (0x04) { 0x01, 0x00, 0x00, 0x00 }, "AAPL,slot-name", Buffer (0x0C) { "PCIe Slot-1" }, "ATY,bin_image", Buffer () { PASTE CONVERTED VBIOS HERE IN ONE LINE THAN COMPILE }, "device_type", Buffer (0x12) { "ATY,IpomoeaParent" }, "VRAM,totalsize", Buffer (0x04) { 0x00, 0x00, 0x00, 0x80 }, "model", Buffer (0x18) { "AMD Radeon HD 6650M 2GB" }, "name", Buffer (0x12) { "ATY,IpomoeaParent" }, "hda-gfx", Buffer (0x0A) { "onboard-1" } }, Local0) DTGP (Arg0, Arg1, Arg2, Arg3, RefOf (Local0)) Return (Local0) } } } is it possible to post an example of your bios that was converted to dsdt? because i did it , and when i open the file ATY to dsdt from using that converter app its like a text file with tons and tons of 0x15 0x01 etc etc etc, like ALOT , not sure how i can make that fit on one line Link to comment Share on other sites More sharing options...
JoachimCraeye Posted February 2, 2016 Share Posted February 2, 2016 Also i would like to ask, how i can make my 'about this mac' window display the correct info, it currently says i have a 6750m 2048 mb , while i have a 6650m 2048 mb i know this is merely a cosmetic thing , but it would be nice if this could be corrected, having the same issue for my ram (displays 8gb while i have 16gb) but i think this is related to my macbook pro 8,3 smbios that probably thinks i have 2 ram slots instead of the 4 my acer has Link to comment Share on other sites More sharing options...

Trucker MK Posted November 16, 2018 Author Share Posted November 16, 2018 (edited) I've managed to load AMD6000Controller.kext, AMDRadeonX3000.kext, AMDLegacyFramebuffer.kext, AMDLegacySupport.kext and IOAcceleratorFamily2.kext and IOAcceleratorFamily2.kext from High Sierra but no QE/Ci either, and never will be possible. High Sierra is the highest mountain that the 6650M will ever climb (and other GPUs with no Metal support).

High Sierra is the highest mountain that the 6650M will ever climb (and other GPUs with no Metal support). So pretty much same like me then. I was thinking about an old project for an old radeon card that enable it's usage in Mac OS systems it wasn't designed for, copy pasting lots of system gpu related files from older system to a new one, "MLPostFactor" but technique used to do it, plus actually doing it, it's really dirty work. Used it once on my old hackintosh HP laptop. Might play around with the technique if I feel like it, might work, who knows. But for now I guess it's just like you've said, 6xxxx with x3000 ends with High Sierra. Link to comment Share on other sites More sharing options...
