  1. Patched AppleUSBXHCI

    Hi, I'm using this on an imac (yosemite) with a this card (Renesas-D720202), then a splitter to 2 usb 3.0 ports. The drivers works but only one usb 3.0 port is working at full speed at the same time: If I plug two usb 3.0 drives, one is recognised as "Superspeed bus" (5Gb/s) while the other as "High-Speed bus" (480Mb/s). If i only plug one drive at a single port it works at 5Gb/s (I can switch port and same speed). Is this a limitation on the kext? or is the card (in the specs it's specified it allows 2 usb 3.0 ports)? Thanks!
  2. Clover General discussion

    Here's the second attachment I made (I was using dsdt.aml to inject it, that's why I didn't use anymore the clover options): http://www.insanelymac.com/forum/topic/284656-clover-general-discussion/?p=2023864 And your answer http://www.insanelymac.com/forum/topic/284656-clover-general-discussion/?p=2023869 Anyway, the whole idea is to fake the ID of the internal GFX (Ati HD 4850, ID 944A, Quail) to another one that will use the 10-bit framebuffer of the HD ATI 4870 (MotMot, ID 9440, which is one of the few 10-bit supported cards under mac os x, but I don't really know if this will work, I'm just trying to). Using gpusniffer, it shows that it's using the 4850 opengl engine, so even if in system profiler the ID has been changed, it seems is only a cosmetic change. As you pointed out: Thanks.

    Hi @Slice, Did you have any chance to look at this?: http://www.insanelymac.com/forum/topic/284656-clover-general-discussion/page-224?do=findComment&comment=2023530 Thanks!
  4. Ati Radeon HD4850 (10bit)

    Tried that but doesn't work. It uses regular 8-bit output.

    I just tried that. I removed the 4850 device ID from ATI4800Controller.kext and injected 4870 FakeID in Clover: hangs on a blue screen and it never gets to the desktop.

    Hi Slice, Did you have any chance to look at this in new revisions?: http://www.insanelymac.com/forum/topic/284656-clover-general-discussion/?p=2024097 I tried Clover_v2k_r2774, but it stills doesn't inject fake ati ID in a real mac. Thanks!
  8. Clover General discussion

    Thanks! Hope this work (but I really don't know for sure if this will enable 10-bit output). The card is capable of, because under bootcamp, when fooled as a firegl card, I get a 10-bit output. I suppose it's not very common to try an alternative bootloader under a real mac

    It's related to deep color, 30 bits (1.073 billion colors), often called 10-bit (per channel) I have a 10-bit display (HP Dreamcolor) that's why I'll like to get 10-bit output from the card. The card is 10-bit capable and works in windows under bootcamp, when its' faked as a firegl pro.

    Here's the full (private dump) darwindump attached. I've also modified config.list to inject ATI fake ID (9440) and the MotMot framebuffer. I was using dsdt.aml to inject it, that's why I didn't use anymore the clover options. Thanks! DarwinDumper_2.8.8_Apple_X64_SL.zip debug.log.zip config.plist.zip
  11. Clover General discussion

    Slice, What sections of the DarwinDumper you'll like to see (so I check them and attach the report)? Only "Devices Properties" or all dumps? BTW, I attach my config.list, my custom DSDT.aml and the clover debug.log. config.plist.zip DSDT.aml.zip debug.log.zip
  12. Clover General discussion

    Hi, I'm not in a hackintosh anymore (I was a hackintosh user a few years ago), I'm using an imac (Ati Radeon HD4850) and I wonder if someone around the community knows if there's a way of faking the system in believing it's a HD 4870 and make it use it's 10-bit framebuffer. I've been able to fake the graphic card ID of my HD 4850 (944A) to use 9440 (which is the HD ATI 4870, one of the few 10-bit supported cards under mac os x) using Clover bootloader on a usb and booting the iMac from it, and tried to force "MotMot" framebuffer (which apparently it's the framebuffer the 4870 use). But it doesn't work. It always load "Quail" framebuffer, which is tied to the 4850 on an imac, verified with "grep | ATY". I've tried inject in the config.plist and also using a custom DSDT. In system profiler the ID has changed to 9440, but using gpusniffer, it reveals that it's using the 4850 opengl engine, so I suspect that this is only a "cosmetic" change, and not a real one. Or I'm failing somewhere in doing it right BTW: - 9440 and 944A are both in the AMD4800Controller.kext, but they are supposed to use different framebuffers. The 9440 "MotMot" and the 944A "Quail". - Tried on Snow Leopard and Mavericks.

    I'll bring back this old subject. I've been able to fake the graphic card ID of my HD 4850 (944A) to use 9440 (which is the HD ATI 4870, one of the few 10-bit supported cards under mac os x) using Clover bootloader on a usb and booting the iMac from it, and tried to force "MotMot" framebuffer (which apparently it's the framebuffer the 4870 use).

    So, anybody? No way to do a softmod for the ati device ID under a real imac? I've explored the possibility of reflashing under windows the card, to change the device ID, but apparently it can make the mac system not bootable.
  15. fake your GFX device id

    Sorry to bring back and old topic, but: will this work on a real mac (an imac)? I want to fake my onboard ATI graphic card and make mac believe it's another device ID (an ATI firegl) and then use their 10-bit display capabilities. The card can do it, but ati only enable it on firegl/firepro (more expensive) cards. So you have to fool the system to activate it. I've been able to softmod it on windows 7 and get this working, but I don't know how to do it on mac without reflashing the bios video card (and I don't like this idea) with another device ID. The whole stuff is here: http://www.insanelymac.com/forum/topic/285862-ati-radeon-hd4850-10bit/ Researching I get into this topic and find it interesting, but I don't know how to change the DSDT and make my imac boot with it as it's not a hackintosh and not using chameleon or a bootloader other than darwin.
