  1. Ciao ragazzi, sono un pò alle prime armi con l'hackintosh e vorrei chiedervi con quale procedura riesco a cambiare il framebuffer?Devo scaricare qualcosa da mettere in qualche cartella particolare del macos? Ho una club3D 6870 e voolevo cambiare il framebuffer da quello standard al duckweed, vorrei utilizzare tre monitor con configurazione DVI - HDMI - DP!!! Grazie a tutti

    HD 6870 DVI Connectors SOLVED

    I have a Gigabyte HD6870 1GB video card and I am running 10.7.3. The card has a DVI-I, DVI-D, HDMI-A, and 2 mini DP connectors on it. I've been trying to get both of the DVI connectors to work with GraphicsEnabler=Yes. I can get them both to work with GraphicsEnabler=No and AtiConfig=Bulrushes. I can get the HDMI port to work with GraphicsEnabler=Yes as well. I don't want to use the HDMI port because it limits the resolution settings on the second monitor. I can't test the mini DP ports because I don't have the adapter. I've read from some of the forums that it is not possible and to buy an adapter. No one really says why. Since I know the card hardware is capable of it, and I can operate both displays under Windows 7 and without GraphicsEnabler I did more research. I tried all of the frame buffers and none of them worked with the 2 displays. I then found the following threads and was hopeful. http://www.insanelym...pic=273937&st=0 http://www.insanelym...hreaded&start=0 I followed the threads and modfied a couple of personalities. I have not been able to get both working. The closest I have got is both displays show up in system info, but the 2nd display has no video signal. I've tried detect displays, unplugging / plugging in. I am working in 64 bit. Some info on the card: Output from radeon_bios_decode: ATOM BIOS Rom: SubsystemVendorID: 0x1458 SubsystemID: 0x21fa IOBaseAddress: 0x0000 Filename: R687OGD.F20 BIOS Bootup Message: GV-R687OC-1GD/F20 PCI ID: 1002:6738 Connector at index 0 Type [@offset 44255]: DisplayPort (10) Encoder [@offset 44259]: INTERNAL_UNIPHY2 (0x21) i2cid [@offset 44383]: 0x90, OSX senseid: 0x1 Connector at index 1 Type [@offset 44265]: DisplayPort (10) Encoder [@offset 44269]: INTERNAL_UNIPHY2 (0x21) i2cid [@offset 44410]: 0x91, OSX senseid: 0x2 Connector at index 2 Type [@offset 44275]: HDMI-A (11) Encoder [@offset 44279]: INTERNAL_UNIPHY1 (0x20) i2cid [@offset 44437]: 0x93, OSX senseid: 0x4 Connector at index 3 Type [@offset 44285]: DVI-D (3) Encoder [@offset 44289]: INTERNAL_UNIPHY1 (0x20) i2cid [@offset 44464]: 0x95, OSX senseid: 0x6 Connector at index 4 Type [@offset 44295]: DVI-I (2) Encoder [@offset 44299]: INTERNAL_UNIPHY (0x1e) i2cid [@offset 44501]: 0x94, OSX senseid: 0x5 Connector at index 5 Type [@offset 44305]: DVI-I (2) Encoder [@offset 44309]: INTERNAL_KLDSCP_DAC1 (0x15) i2cid [@offset 44501]: 0x94, OSX senseid: 0x5 Output from redsock_bios_decode: R687OGD.F20 : GV-R687OC-1GD/F20 Subsystem Vendor ID: 1458 Subsystem ID: 21fa Object Header Structure Size: 407 Connector Object Table Offset: 52 Router Object Table Offset: 0 Encoder Object Table Offset: 12a Display Path Table Offset: 12 Connector Object Id [19] which is [DISPLAY_PORT] encoder obj id [0x21] which is [iNTERNAL_UNIPHY2 (osx txmit 0x12 [duallink 0x2] enc 0x4)] linkb: false Connector Object Id [19] which is [DISPLAY_PORT] encoder obj id [0x21] which is [iNTERNAL_UNIPHY2 (osx txmit 0x22 [duallink 0x2] enc 0x5)] linkb: true Connector Object Id [12] which is [HDMI_TYPE_A] encoder obj id [0x20] which is [iNTERNAL_UNIPHY1 (osx txmit 0x11 [duallink 0x1] enc 0x2)] linkb: false Connector Object Id [3] which is [DVI_D] encoder obj id [0x20] which is [iNTERNAL_UNIPHY1 (osx txmit 0x11 [duallink 0x1] enc 0x2)] linkb: false Connector Object Id [2] which is [DVI_I] encoder obj id [0x1e] which is [iNTERNAL_UNIPHY (osx txmit 0x10 [duallink 0x0] enc 0x0)] linkb: false Connector Object Id [2] which is [DVI_I] encoder obj id [0x15] which is [iNTERNAL_KLDSCP_DAC1 (osx txmit 0x00 enc 0x10?)] linkb: false You can see that from the redsock output the HDMI and DVI-D connector share the same transmitter and encoder. I did not think that was going to be a problem since I'm not using the HDMI port. The way I see it if something was plugged in to the HDMI it would turn off the DVI-D and vice versa. Plus they have different senseid numbers. Here is my current framebuffer, which is a modified Gibba. 0000000: 0004 0000 0403 0000 0001 0000 1204 0101 ................ 0000010: 0004 0000 0403 0000 0001 0000 2205 0502 ............"... 0000020: 0008 0000 0402 0000 0001 0000 2205 0304 ............"... 0000030: 0400 0000 0400 0000 0001 0000 1102 0406 ................ 0000040: 0400 0000 1400 0000 0001 0000 1000 0605 ................ Connector 0 mini DP Connector 1 mini DP Connector 2 HDMI-A Connector 3 DVI-D Connector 4 DVI-I I tested performance under Duckweed using Cinebench and compared to Gibba. Both where very close, Gibba was slightly better. Duckweed is what the system defaults to with GraphicsEnabler=Yes. I took the Duckweed personality since it matched except for the DVi-D connector and used it in Gibba which has the correct number of connectors. I used IOregistryExplorer to determine the connector type, and control flags for the 2 DVI connectors under GraphicsEnabler=No. The above was the last iteration, I tried changing the transmitter/encoder for the HDMI connector because it was the same as the DVI-D. Like I said I've tried a lot of combinations and none have worked. Before I go out and buy the adapter I am wondering: If it is not possible to use both DVI connectors with GraphicsEnabler=yes why? Is there a way to determine the proper hotplug ID numbers? Changing these sometimes causes the mouse pointer to lag. I've read that in certain cases the hotplug id needs to match the sense id of a neighbooring connector so that if one is plugged in the other will turn off. Does the framebuffer personality have to have the correct number of connectors that the card has? If I am only using 2 connectors is it possible just to have 2 entries in the framebuffer personality and extra ones for the unused connectors? Thanks for any info. UPDATE UPDATE SUCCESS SUCCESS :guitar: See FishCow post below. As I said in my response I thought I tried VCH888 Gibba frame buffer but I must not have.... Here is VCH888's edited framebuffer.

  3. Hi All After days trying finally I got the hdmi working but not the dvi, but my monitor is connected to dvi and the tv is connected to hdmi please help me, how to activate the dvi. Attached my efi folder EFI.zip
  4. Hi everybody, I am currently working on getting a 2 Screen setup to work with my system. I have a recent 27" Shimian QH270 (DVI) with 2560x1440 max. and a pretty old MEDION MD7218AR (VGA) with 1280x1024 max. The very first step was to make my ports work. For this I edited my Duckweed Personality after reading Alexander Martinez' Guide, and bcc9's Thread. My first problem was I had no Windows Partition and no HDD lying around. Tried for days to get almost every Windows working on externals without luck. Then stumbled upon this Guide from rampagedev which is basically a round-up of all the others and went for the DOS way. When I was already set up to work my way through all personalities I found fffeee's Post who has exactly my card. So I thought I'd give it a try and just edit my Duckweed as he did. This is the as-is for now. My DVI Ports both work, which is what I needed. (Can't even test HDMI and DP) [ DVI-I(DL) ]✔ [ HDMI ] [ DP ] [ DVI-D(DL) ]✔ My Problem: When I connect the DVI-D Cable of the 27" to the DVI-D Port I don't get support for no-VESA resolutions (which is 2560x1440). When I connect it to the DVI-I Port, the Screen gets full resolution support. This is troublesome, since I have no chance to connect the VGA Adapter to any other port than the DVI-D. I came across this thread about VESA modes but it actually refers to the boot screen only. I did try to edit my ROM and load it with AtiROM=Yes but failed in editing I suppose since system didn't even load. My Boot.plist Custom DSDT GraphicsEnabler=Yes AtiConfig=Duckweed AtiPorts=4 GraphicsMode=2560x1440x32 My Question(s): 1) Is there anybody out there with a) experiences with similar cards + edited framebuffers + screen sizes or even with similar working setups? 2) Do you have any ideas/tips for me on what to work on to get support for the desired resolution on that port? (VESA/Framebuffer/Other?) My System: Mainboard: GA-H77-D3H (EFI F10) CPU: Intel Xeon E3-1230V2 GPU: Sapphire HD6870 1024MB (Barts XT RV940) GPU VenID: 1002 GPU DevID: 6738 GPU SubSysID: 174b OS: 10.8.3 (12D78) For further input I can post more details if necessary. Hope anybody has some ideas floating in their head. Greetings Deri~

  6. Hi all, So I have done some pretty extensive searching and can't seem to find a straight answer on if/how this is possible. I am currently trying to use my 46" (I believe) Panasonic Viera TV to display my mac running OSx El Capitan. I can get it running just fine using the VGA port, but I have a DVI to HDMI converter, and have been running my Windows partition using that without any problems. When I try to hook it up to mac, the OS freezes. Everything else is running fine! Would love the help if anyone has any suggestions. Current Machine Motherboard - ASUS P5QC with custom DSDT Processor - Intel Core 2 Duo 4 core @ 2.4Ghz Video Card - EVGA e-GeForce 9800 (uses 980 chipset)
  7. I am currently working on a G5 ATX conversion but I have one thing which I yet have to decide. I really want to keep the stock look on the back of my G5. But the problem, of course, is the fact that fitting the motherboard directly to the back of the case will force you to cut out space for the motherboard I/O panel. Thinking of this, I came up with the idea of placing the motherboard slightly to the front of the case (so the PCI cards will not be mounted directly to the rear slots). When a GPU is installed, I could simply use a DVI bracket with a DVI extension cable attached to extend the video output to the rear slots. Common version Alternative A DVI bracket: This might work, although I have two major concerns: - I am planning to use a high power GPU (ATI HD5850) in this build. The GPU blows out it's heat at the back of the card, through its mounting bracket. When placing the back of the GPU in the case, the GPU may not be able to blow all it's heat out of the case. This may be solvable by making a air duct which extends to the back of the case to guide the heat out of it. I would also replace the stock expansion slot brackets with ones with ventilation holes. - Is it okay to fit a pretty heavy GPU just to a PCIe-slot, instead of also attaching it with a screw to the case? I'm slightly worried about the amount of weight which will be put on the motherboard because the GPU is not attached to the case itself. I am planning on using a Gigabyte M-ATX motherboard with this build. I would really appreciate any feedback, thanks in advance!
  8. Hey guys, recently purchased a Belkin 4 port KVM... this thing is terrible. Model F1DD104L Belkin specifically states support for Mac OSX systems, however the current corded Apple aluminium keyboard and optical mouse do not work at all. Keyboard is not recognised at all by the system... and inputs the character 'z' permanently. Mouse is jumping all over the place. Leaving artifacts all over my screen in the dark areas. Their excuse is the product works with OSX, just not Apple peripherals. Seeking RMA now, what a nightmare! Looking for anyone who has gone through this before and found a solution that works with switching macs. I will need DVI-D DUAL LINK as my monitor is the 30" 2560x1600 Apple cinema display. Plus USB switching. Audio not as important as I can do this with my amplifier but I guess most KVMs have this included. Looking at ATEN, Gefen, ServerLink, IOgear etc. Budget is $300. Also does anyone know if I will need a DVI booster to get rid of these screen artifacts or will a decent KVM help? Thanks! Danny
  9. Hello! Does anyone know if R9 285 or R9 280 work OOB in Yosemite?I know for sure that R9 280X does,but I'm not sure about these two cards..I haven't found many topics in which they are mentioned, and I want to be sure that HDMI and DVI work OOB..has anyone tested them?I don't want to buy a graphics card and then have to return it and buy another one..
