SL 10.6.6 + GT220 + QE/CI Working... almost

[AVO-Electronics]

Hi,

 

So I changed my mind and bought a cheap GT220 for now.

I wanted to make sure this hack is gonna be reliable.

 

I've got 10.6.6 installed happily and my GT220 seems to be running with QE/CI with an EFI String only.

The gfx is a Zotac GT220 1GB DDR2 Fanless if anyone's interested.

 

I haven't test real high resolutions as my workshop monitor won't run very high.

But also, the problem I have is to do with the DVI port.

 

The vga port seems to work fine, other than the poop quality it offers.

So I attached a DVI to vga adapter to the gfx and ran it into my workshop monitor to the vga in.

The boot process worked fine and I got the verbose output from bootup until the very moment the desktop loaded and it went black.

 

So I'm not sure where to go from here.

 

I'll iterate;

 

VGA = works fine QE/CI good resolutions.

DVI = gives boot up logo and verbose output until desktop loads and then screen goes black.

HDMI = untested as I have no hdmi screen.

 

Now I think I read that you can only use the following combinations;

VGA + HDMI

DVI + HDMI

 

But not:

VGA + DVI

 

Which is fine as I don't need any dual output. Furthermore, when I tested the DVI output I detached all other connections. The only thing I might have a problem with is the DVI-VGA adapter I used, although it is Dual Link DVI as well as the gfx.

 

So, where do I go from here?

UPDATE:

 

I used nvflash in dos to get the correct NVCAP for my card.

Once I added that to the EFI String the DVI partially worked in that I can now boot to the desktop.

The problem I have now is that the resolution is set at 800x600 and if I try changing it even to 1024x768 it hits a blue screen and stops. 15 Seconds later it tries to revert back to the original setting and flickers a few times but then stays blue.

 

I then have to restart.

 

Again, the VGA port works flawlessly but I need DVI.

 

Any ideas?

UPDATE: I've test the HDMI and that doesn't work either damit.

 

What to do?

Which version of Chameleon are you using?

 

It shouldn't make any difference but have you tried using GraphicsEnabler=Yes in c.a.B.p ?

Hi,

 

I'm using the latest myhack which means;

 

Chameleon-2.0-RC4 with PCEFI-10.5

 

I tried GraphicsEnabler=Yes to start with, on its own. But it never give me any resolutions or QE.

 

I haven't tried GraphicsEnabler with efi because I thought the idea was to use only one solution. That is, GraphicsEnabler, kext or efi string, but not more than one.

 

Oh and is it GraphicsEnabler=Yes or =y or either?

 

Thanks

I was also using EFI strings until updating to RC5 and graphicsenabler as it solved the card identification issues I was having with RC4. Might be worth trying to update to RC5 as you'll also get the benefit of native power management if your lucky.

 

Yes your right about one or the other. So don't try to run both the video EFI string and graphicsenabler at the same time. I use "Yes" in my Boot.plist but I think either will work.

Hi, I was wondering what EFI you were using to get your GT220 working in the first place?

I have iatkos plus updates to 10.6.6 running on a Dell SC440.

If I disable the Graphics Enabler using [url="http://www.insanelymac.com/forum/topic/279450-why-insanelymac-does-not-support-tonymacx86/"]#####[/url] (install the bootloader x64 diable graphics enabler) then I get standard resolution from the VGA output of the GT220.

I don't think I have any other kexts or anything installed.

 

Unfortunately, even coming from linux, I am a bit bewildered by the EFI/DSDT/kext routes and the difference between them.

 

Thanks for any help!
