  1. Information on VESA modes in ATI&NVIDIA bios

    That would be awesome!
  2. Information on VESA modes in ATI&NVIDIA bios

    But is there any way to disable underscan even before booting any OS?
  3. Information on VESA modes in ATI&NVIDIA bios

    Yes, I changed the theme size as well. I believe it might be a BIOS limitation, because the BIOS screen and POST screen have the same borders, even before loading anything of any OS. Interesting to note, when I shut OS X down, there are a few lines on a black screen, but this time they fit the whole screen.
  4. Information on VESA modes in ATI&NVIDIA bios

    I have the same problem, with an HD 4850. I noticed the resolution did change, because during boot there were some lines that wouldn't fit in one line and now it does. Besides, in case of any problem with my monitor, I believe it would be safer to have 800x600 mode. I guess it'd be better to replace another "less useful" resolution, perhaps 1152x864. How can I do that? Edit: another reason, look what happened to my BIOS screen (previously, it was fullscreen, almost full, with the same black borders). Edit2: I managed to replace 1600x1200 with 1920x1080, so BIOS went back to normal, but I still have those borders.
  5. Can't boot with DSDT (neither original or patched)

    I read that topic before, but no matter what I changed, I couldn't boot. So I decided to analise one of his DSDT and I found out that it contains the same 4 errors I have. I thought, there are errors, but maybe they should be there for some weird reason, I need to figure out how to compile it anyway. I found this app AML <-> DSL which can do that, and now I can boot! I guess I'll start from scratch, one patch at a time then. Do you have a "patch order" to suggest? Some are "more essential" then others?
  6. Can't boot with DSDT (neither original or patched)

    I must change every reference of Windows to Darwin, then? I have Windows 7.
  7. Can't boot with DSDT (neither original or patched)

    I checked the BIOS, the drives are set "RAID Autodetect / AHCI", and says "Uses RAID when signed, AHCI otherwise". I can change to "RAID On", but I'm warned my OSs may not boot after changing and I may need to reinstall them. If this happen, can I simple change back and it will work as now? Latin, what do you mean by "osid fixed to Darwin"?
  8. Can't boot with DSDT (neither original or patched)

    @Latin Sata is black, if I'm not mistaken. There's a white e-Sata, I'm sure it's not being used. DVD is also Sata. I always boot with -v, the only message is "Still waiting...". I'm going to change to RAID. @James How can I get the output?
  9. Can't boot with DSDT (neither original or patched)

    I have a Dell Optiplex 755 (BIOS A21) and I'm having a rough time trying to patch it's DSDT. Whenever I tried, either using a bunch of patches or one at a time, I couldn't boot, always with the error "Still waiting for root device". At last I decided to try with absolutely no patch, just extract, compile and save. Guess what, still have the same error. Now I wonder, is this supposed to happen? I don't think so. Besides, at first compilation there are 4 errors (an dozens of warnings, remarks and optimizations), however DSDT Editor is able to fix these errors. I feel like I'm a dummy on this subject, but I really didn't expect the original DSDT to contain so many errors and warnings. I attached the the extracted DSL file if anyone care to take a look on it. I'm using the latest Chameleon version and I can boot finely if DSDT is disabled. I really look forward to solving this because it might be extremely handful with my "audio via HDMI problem". Original.dsl.zip
  10. Editing custom personalities for ATI Radeon HD[45]xx

    Hey guys, I've been reading the forums these last couple of weeks, and I could install Lion on my PC, everything is almost fine, except audio via HDMI. I have an ATI 4850 with 2 DVI ports and I'm using a DVI-HDMI adapter (which includes sound, it works on Windows). According to IORegistry and Chameleon boot info, the personality of this card is MotMot. I ran that perl script and got this: Personality: MotMot ConnectorInfo count in decimal: 2 Disk offset in decimal 462408 0000000 00 04 00 00 04 01 00 00 00 01 00 00 10 00 02 03 // Display Port 0000010 04 00 00 00 14 02 00 00 00 01 00 00 01 11 01 04 // Dual Link DVI 0000020 As you can see, there is no HDMI port. Moreover, there's a DisplayPort on the first line. This is bugging me... I expected 2 DVI ports, got DP + DVI instead. I'm running Lion, so I looked for these strings on ATI4800Controller.kext. I did found them, twice. (Edit: I read again, one occurrence for 32-bit, the other for 64-bit, right?) Now it's time to do the trick and "convert" one of them into an HDMI port, but I have no idea how to do this. In the example, the OP copied the "unused" port 3 into port 2, but in my case how should I change the string? I forgot to mention, on ATI4800Controller's Info.plist there's an entry named Cardinal instead of MotMot. So now I don't know which of them I need do edit.
