  1. Making Some Progress with my 7970

    Got it working! I switched to one of the mini display ports on the video card, and connect to my monitor via MDP->HDMI adapter. At boot time, I use the 'Aji' frame buffer. This boots me to a white screen; then I just use the "sleep trick", and I get to my desktop!
  2. Making Some Progress with my 7970

    No sleep trick; I read that only works when you get a white screen anyway. I just boot straight with Clover; Graphics Injector is set to 'Yes', and I use the 'Aji' framebuffer. Maybe I will try leaving the 'boot args' line empty? Despite having a black screen, I know I am at the desktop since various special function keys on my Mac keyboard are working as they should (like drive eject). I'm wondering if there is still another framebuffer I should be trying; so far I've tried: Futomaki, Chutaro, and Aji. 'Aji' is the only one that gets me to the desktop.
  3. I'm still trying to get my 7970 working with 10.8.3 & Clover. Finally though, I'm making some progress... At the Clover boot prompt, I modify my boot args to read only: GraphicsEnabler=No. Also, I set the FrameBuffer to: Aji. Using these params, my system boots me to to my desktop; I no longer get a "No Signal" on my display. The problem is, my screen is totally black. Any ideas as to what parameter combination might work for me?
  4. Problem with 7970 & 10.8.3

    It is after OSX is booted. I was wondering if this could be a framebuffer issue? I do not know enough about using Clover though, so I'm not sure if there is a way to select a boot-time framebuffer... So far, I have only tried using the HDMI port...
  5. My board is a Gigabyte Z77-UP5 TH. Here are the steps I followed: 1) Clean install of 10.8.3 using the integrated graphics for video. 2) Use #####, and get a working system. 3) Install the Clover bootloader. 4) Shut down. 5) Insert my MSI R7970, and connect my display to it via HDMI port. 6) Power-up. OSX clearly boot up, as I can hear the 7970 fan get whisper quiet (as when drivers load), but all I get is a black screen with the "No Signal" message on it. So, I reset the system, but this time boot while connected to my integrated graphics. Now everything seems fine. If I look in "System Profiler", my AMD card shows up as it should: "AMD Radeon 7970-X". However, if I connect my display to the card, I once again get a black screen with the "No Signal" message displayed. Anyone have any ideas of what the problem might be? What can I try to get this working?
  6. OpenGL Speed

    I see the same thing too. With my GTX 480: OpenCL test via Luxmark runs, but gives very low score. OpenGL Extensions tests yield very low results (around 1500fps). With my GTX 580: OpenCL test via Luxmark, gives error that no OpenCL device has been detected. OpenGL Extensions tests yield the same low results that the GTX 480 got. Interestingly enough, CInebench yields better scores with both of the cards -- around 40-43 fps, but these are still lower than I got in Lion.
  7. Okay. I redid the USB stick from scratch, and I can now at least get ML installed. I'll play around with it tomorrow, but I thought I'd share this... In order to get to the ML install screen, I had to use a boot line that read: -v PCIRootUID=1 npci=0x2000.
  8. Not working for me. I barely kick-off the boot loader, and then get a kernel panic: message like "no driver found (ACPI .....)". I have no problem with Snow Leopard or Lion installs though. Any boot params I could try?
  9. Well, I tried the guide written by smegoid -- Unfortuneately, even though we use the same motherboard (Asus P6T Deluxe v2), I still have problems. 1) I cannot get that DSDT patch to work -- I still show 1 processor + 4 cores in System Profiler. 2) My system RAM is being reported incorrectly -- I am using DDR3 at 1066, but it is being reported as DDR2 at 667 in System Profiler. Anyone have any ideas as to what the trouble might be?
  10. Question about the "sudo" command

    I am logged in under my user account (no password on that). I have no idea what the sudo password is supposed to be.
  11. I have been following the Leopard installation guide for my PC with Asus P6T Deluxe MB. Everything goes okay, except for the section about modifying the EFI partition. Those instructions start by having you go to a terminal window, and type "sudo -s". The first thing I get is a password prompt -- my question is, what do I need to enter here? I thought that the password here is the same as your user password; right now, I have been just pressing "Return", as I never created a password for my user account. Anyway, it doesn't seem to work, as I just get back to my usual terminal prompt -- if the sudo was working, wouldn't I get a new prompt (like when you log in as 'su' on UNIX)? Can someone please straighten me out on how this is supposed to work? Thanks in advance.
  12. Well, I am running into a problem during Phase II, Step 4 --- whenever I try to use the fdisk command line, I am always getting a permission denied error. 'fdisk' by itself executes (brings up options), but whenever I add rdisk0 to the line, it's always permission denied. Even using 'sudo' doesn't fix the problem. Any ideas that could help me get past this? Info -- Asus P6T Deluxe V2 MB, hard drive is single partitioned (GUID), installed retail 10.5.1. Thanks in advance.
