Dell Optiplex gx620 hackintosh Graphics Card Issue. Please help?

Hi i just installed OS X on my dell optiplex gx620 using this method:




Everything works perfect except for when I insert my ATI MSI R5450 MDIGH 1GB DDR3

graphics card into my system..the iHack screen loads up fine..but right after, the screen goes

black as if the monitor shuts off..but the system keeps running..but the monitor won't respond.


I was wondering if anyone could help me out or give me some insight.


The only other concern I have is, I'm not sure how or where to find my MAC address

and password. It still remains as 00:00:00:00:00:00. When I edited it in applescript as

instructed, I just changed the password to something I just made up on the spot. I am

not sure if there's already a MAC address and password assigned or where to find it. I

am wondering if all I have to do is insert my old hd with windows 7 to look up the MAC

address and pw first before editing this.


Other than that, I am highly pleased that I'm running snow leopard with audio and ethernet

working. I would just love to be able to top it off with the hd graphics card that I have

lying around. I appreciate any help! Thank you!


p.s. after this issue resolves I was always wondering any other additions I could add to

my hackintosh to make it more awesome..as in accessories/hardware or software.

Thanks again!

2 main issues.. needs to use -v -f npci=0x2000 PciRoot=1 (try changing to 4 .. seen some dells say 4)


OR in dsdt likely needs Device (PCI0) under it the _UID, Zero


what cpu u got ?

i think i have a patched gx620 dsdt somewhere..

can u dump dsdt in linux live from usb bootable ?

install from terminal acpidump and iasl tools:

sudo apt-get install acpidump iasl

### or

sudo yum install pmtools iasl

Then run the following commands on a bash terminal:

mkdir ~/acpiinfo ; cd ~/acpiinfo

sudo acpidump > acpidump.txt

sudo acpixtract acpidump.txt

ls *.dat | while read i; do iasl -d "${i}"; done

name=`sudo dmidecode -s system-product-name`

mkdir "${name}" && cp *.dsl "${name}"/


now the folder in live users folder can be zipped and uploaded to forum or mediafire like site.



also .. is your ATI supported by GraphicsEnabler ?


os X version.. chameleon version.

I'm running osx fine from the onboard vga...just not when I pug in the hd video card. There's not a way to install a driver to make it work?

When you say try booring iwthout eliotlegacyrtc ...how do I go about doing that? Forgive me again for being a noob.
