nVidia GTS250 512MB DDR3 resolution issue

m3s_4ev3r · #1 12-23-2009, 07:17 PM

Hello, this is my first post and the first time I installed a MAC OS X - iATKOS v7. I am beginner at this, eager to learn...

I have read tutorials and used trial and error to install it, and in the end, it works, the only problems that I have are the graphic card and audio.

After the 3rd trial and error the OS started and the first thing I tried was to modify the display resolution to 1920x1080, everything went blue, and it stayed like that, only after pressing the shutdown button on my PC the image would appear for a moment and then reboot.

I know that in linux there is a file where the resolutions are stored, I didn't find it so I reinstalled, and now I am at 1360x768, and afraid to change it until I find out how to fix it if it goes all blue on me

What I want to accomplish:
- use 1920 x1080 (if I fail who knows where the X's resolution file is?, help)
- be able to use OpenGL acceleration in PhotoshopCS4.
- make the audio work.

On iAKTOS's installation I choose the following settings:
iAtkos v7 Main System
Chameleon V2
Extra Directory
DSDT
AppleDecrypt ???? (or smt like that)
9.7.0 Kernel Voodo
APIC Driver
Disabler
OHR
Remove TyMCE
nVidia Enabler (just the one under it, will document later)
GT200 driver
AHCI
nForce S-ata/IDE
Azalia Audio Driver (with Voodoo HDA the system will not boot, the boot log shows that device can't start/not found), with azalia still not found but the system boots
Realtek and nForce wired netwrok cards
Post-Install

Where is located the file in which I can change the resolution if I get stuck on that blue screen (ironic, blue, a brighter blue, but still blue

) )?
---
(what is the command for opening a file, editing it and saving it in terminal? that is with X11 being down)
---
What would the best nVidia driver be for my card that will allow OpenGL in Photoshop and be able to change the resolution to 1920x1080 on my BenQ 2200HDA(DVI/VGA)?
---
How can I install a driver (will Google it too)?

Thanks a lot, ARTHUR.

iATKos v7 is Leopard 10.5, the nVidia GTS & GTX 2xx series isn't officially supported till Snow Leopard 10.6.2 so you'll either have to upgrade to Snow Leopard (recommended) or back port the nVidia drivers from 10.6.2.

Hey, so I installed 10.6.0, booted succesfully after ihackintosh's tutorial,

being dumb I set my resolution to 1920x1080, the screen turned blue,
I enter safe mode, did almost nothing restarted and then everything worked on 1920x1080,
I updated to 10.6.2 the blue screen appears sometimes, other time a black screen on which I see my mouse.

from my 10.5.8 I deleted Library/Preference/xxxxxxx.windowserver.xxxx where the settings are and still that blue screen,
The funny thing is that exactly when I push the reset button the blue screen goes away and I can see the desktop and it is at 1920x1080...

Where can I reset those settings? so that It will go back to the default resolution, besides the file in Lib./Pref.?

THANKS!

REsolution is Fixed with GFX Util, OpenGL enabled in Photoshop works just COOOOL, the only problem graphics related that persists is that everytime I boot into Snow Leopard 10.6.2 I have to wait for 4-5 minutes of blank screen(only mouse) until the desktop is visible.

And now comes the audio, I think that will be a real challenge.

Well for that you may be missing a kext somewhere or you need to mod your DSDT.

I tried
VoodooHDA, different versions and architectures.
AppleHDA(HDAPatcher doesn't work)
Azalia

in different combinations, by adding my own hex code in plist and so on. Right now I am really confused. Nothing works, somewhere I may have mistaken or the methods and kexts I tried really aren't working with my sound card, I also tried all the above listed kexts in different BIOS configurations (External Codec Only, External+Internal[VoodooHDA panics like that], Front Panel AC97, Front Panel HDA[voodoohda actually sees somethings there, device 0 no pcm channels found])

Right not there's a big mash in my head, I don't from which side to take it. I have a linux codec dump for my VT1708B(attached), what are the following steps:
- hex the file
- ..... I am lost here,
how can I manually create a kext to install and what sould I use, AppleHDA or VoodooHDA.

Can someone create that kext file and upload(that would be to easy for me)

I think that after I solve this I will try to make a very comprehensive tutorial for my mobo + nVidia GTS250 512DDR3 so that people won't have to go through the headaches that I did/do.

UPDATE: I also have a windows 7 on my other hdd, and although I reseted to default all the BIOS settings, the audio won't work in windows 7 now... the only thing available in W7 is HMDI Audio.

So apparently I physically broke me external codec in all my attempts(if that's even possible), that is just great!

EDIT: MY windows was stupid, audio works, it must have been confused that I meddled with the BIOS settings, audio works in Windows again

Honestly I can't find anything regarding the VIA codec your sound uses and OSX so you may end up having to go out and buy a sound card that is compatible. As for your slow boot time I recommend you try patching your DSDT with the HPET patches.

\ Actually you need this patched ioatafamily.kext to fixed bootime.

You misunderstood me, the boot time is ok, I always boot in verbose mode to see what's going on, and it boots in 30-40 seconds it enters the desktop i see the mouse and then everything goes black or blue until the screensaver kicks in, only then I can use it.

I really don't want to buy another soundcard, I have to make a kext that tells the system all the details about my soundcard, I just don't know how, like creating my own customized driver, I have the codec dump already, that is all the information the system would need, but how do I make a kext of it? Injection in AppleHDA with HDAInjector doesn't work, ("sound card not recognized", I thought that this should actually add my soundcard's driver to AppleHDA, how can it be not recognized?)

EDIT: I really want to use MacOSX because my win has been severely compromised with al sorts of malware and viruses and I lost 60-70% of the last 2-3 years of work.
I need a operating system in which I can run Adobe Master collection, and linux's wine does not help, otherwise I would've went directly to linux, because Ubuntu recognizes my hardware instantly and by default/out of the box, which is really weird no one has made a mod for MacOSX with my mobo in mind, because this mobo was available in june 2008, almost one and a half year and only few people tried MacOSX on this mobo.

There's a guy here on the forum with my mobo that says with iAKTOSv7 and VoodooHDA it works out of the box, iAtkos v7 was the first thing I tried, but no luck so far, I switched to 10.6.2 for better support for my graphic card and now the audio problem is nagging me.

Here you go an extremely cheap usb audio adapter that will just work, since voodoohda is your only hope to get your via audio codec to work and its not, buying an usb external sound card seems the best solution for your problem.
