I have an VIA S3/Unichrome and now I have only 1024*768 resolution.
I just want to have 1280*1024.

So I tried to install AGPGart and it seems to load because it appears in my kexstat list.
But I cannot change resolution.

I tried also to change resolution in this boot file, but it just gave my an error restarting.

Is there a way to change resolution on this card?

Thanks!

Second thing is that I only have left audio on my sound card.
It's a VIA 8237.
Is there a way to have stereo?

I tryed that <string>1280x1024x32@60</string> but when I tryed to restart I had a problem and I had to remove this from the plist.
Maybe the @60 is the difference but I am not sure this will change a lot.

For the sound, I have now the left channel with Cartri version of the kext, but the sound is quite bad and I think it's because the sound is playing 48KHz instead of 44.1KHz.
I cannot set up this in MIDI/Audio application because it is said that the output is not supported...

Maybe I'll try without @60 in the plist and say if it's better...

Thank you for help!

Ok, so I tryed your plist and I have 1024*768 resolution. So it does not change my resolution...
For the audio file you put, I think the archive is corrupted because it does not look like a real kext.

So I'll search a little bit further if I can found an driver to change resolution...

Thanks you again!

Ok, then I have now a good working audio.

Now, I just have to deal with resolution.
I just have 1024x768 and I want 1280x1024.
That's my last problem to make all work for me.

So, I have this plist :
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN" "http://www.apple.com...yList-1.0.dtd">
<plist version="1.0">
<dict>
<key>Kernel</key>
<string>mach_kernel</string>
<key>Kernel Flags</key>
<string></string>
<key>Boot Graphics</key>
<string>Yes</string>
<key>Graphic Mode</key>
<string>1280x1024x32</string>
</dict>
</plist>

But it does not work at all.
Maybe there is another problem with monitor or something else...
My screen is a Philips 19 LCD 19OS6.

Thank for all help!

Check your syntax. You have:
<key>Graphic Mode</key>

it should be:
<key>Graphics Mode</key>

And after you fix the syntax, go ahead and try:
<string>1280x1024x32@60</string>

Ok, it works perfectly!
I don't how I did but very bad each time because it works like a charm right now.

Thank you so much!

I have now all what I want for my Hackintosh.

One thing more I saw is that samba is generating big log files and always writting to disk.
So if you want to increase speed, just disable Windows sharing and it's gonna work better.

I'm glad you've got it working now. Sometimes it just takes a fresh set of eyes to spot a simple misspelled word. I've had problems in other areas that drove me crazy for hours, and then someone else spots the error right away.

How Did you fix your AC97' Audio? I too only have sound out the left channel, and it is very sloppy sounding. Thanks in Advanced.

It is strange. I had quite good sound, but, now, I don't know after what (I did no install any new driver), the sound is very bad, it looks like an old 96Ko/s mp3 encoded.
We just can hear the trebble. It looks like a bad equilisation but there is no selected.
Maybe the music is going faster or slower, but I can't hear that.
I took a look at the midi/audio panel and it says 16bit stereo - 48KHz, it sounds ok. I tried with 44KHz or 8bits and it was worse.

So, I can't remeber if there were a 96KHz setting before...

Do you have an explanation?

Thanks

Okay, This is strange, I turned on my Hackintosh this morning and for some odd reason I have sound from both channels and it sounds good. I made absolutly no adjustments to the sound. All I done was set my Screen Resolution. So this is strange, but sure enough, I have sound from both speakers.

I have read in other posts that removing all the ATI .kexts from the System/Library/Extensions folder will help the AC 97' Audio but I did not choose to install any of the ATI drivers during installation, So I do not know how valid this information is.

JaS (Mac) OS x86 10.4.8
VIA P4M800-Intel Pentium D Duel Core 2.4GhZ
S3G UniChrome Graphics @ 1440x900
AC 97' Audio
512Mb Ram

Thanks for Help.

You must use a patched driver. Like AC 97' Audio.

Or maybe you just have to edit the plist file from the kext AC 97' Audio.

You can also use patched AppleHDA.

I think you can find all these in the wiki. What is your motherboard exactly?

Hello SuperCed

I came to read your post after long investigations.
I have just the same video card and the same problem.
Can you help me about the AGPgart you installed for this video card?
Can you please send me the AGPgart to my email address?
My email is fusmacho@gmail.com
Thanks in advance

With this video card, I was not able to get full support.

I was just able to have VESA mode and I had to select my resolution in the boot.plist.

So AGPGart is not doing more than this.

And you won't have any acceleration (no CI, no QE, no accelerated openGL).

It's not a good vedio card.

Do you only have a VESA display?
