Leopard 10.5.7 on Dell Optiplex GX620

[be2003]

Mac OS X - 10.5.7 on Dell Optiplex GX620

 

This is the first time I installed OS X on any pc, and it only took one night. Follow my instructions carefully and it should take you less time than it took me.

 

NOTE: At the time of install I had a stock GX620 with onboard video and sound, no ps/2 mouse or keyboard connectors, only usb ports. A Pentium D Dual Core 3.2GHz and 2 GB RAM. I also had a Linksys Wireless PCI Card installed. (WMP54GS v1.1)

 

Things you'll need:

1. iAtkos v7

2. A patched version of AppleAC97Audio.kext (I will explain how to patch it later in the post)

You'll have to search the forums or the web to find either. DON'T ask me for them. I probably won't ever be on these forums after this post.

 

Step 1 -

Boot the computer from the iAtkos disk, just hit ENTER when prompted.

If you have any trouble extracting the iso from the rar, or burning the iso to a disk, ask your good friend google. Imgburn told me multiple times when verifying the write that there was an error but the install worked perfectly.

 

Step 2 -

Select Disk Utility from the Menu Items and Partition the Drive, choose Mac OS Extended Journaled (I haven't tried using any other format) with 1 partition (if you are not dual booting).

 

Note: You must partition the disk before you get the disk selection window of the installation process. Otherwise Disk Utility will give you an error and wont partition the disk. To solve this exit Disk Utility, go back in the installation process window, and restart Disk Utility.

 

Step 3 - Install

Select the disk partion you just created and click Customize in the bottom left corner.

 

Select the following drivers and files: (Leave the defaults alone unless you have a reason to change them)

 

1. X86 Patches -> Kernel -> 9.7.0 Kernel voodoo (Enable it)

I didn't try 9.5.0, it might also work, just don't enable both

 

2. Drivers -> VGA -> Intel -> GMA 950 -> GMA 950 Desktop (Enable it)

This is only if you're using the onboard graphics, if you use an NVidia or ATI card you might have to do a search and figure out which option works best for you.

 

3. System -> SATA/IDE -> Intel SATA/IDE (Enable it)

If you're not using a the stock SATA hard drive and are using an IDE hard drive you might want to enable Generic IDE instead, but this tutorial only covers the stock GX620 so do some research, once again i suggest you ask google.

 

4. System -> Sound -> Voodoo HDA driver (DISABLE it)

I only say disable it because it doesn't work for the GX620's onboard audio. I will have to explain how to get the audio working later in the post.

(If you aren't using the onboard audio card and have something different installed then it might not hurt to leave this enabled, it might work for you, I have no idea)

 

5. My model GX620 doesn't include PS/2 ports so if you need to use the PS/2 and they aren't working you might need to enable either the Voodoo PS/2 driver or the Apple PS/2 driver. Avoid enabling both.

 

6. Network -> Wired -> Broadcom -> Broadcom BCM5751 (Enable it)

I haven't tested it myself because I only use the wireless card I mentioned earlier. But supposedly this is the correct option for the onboard ethernet.

(For users who are also using the WMP54GS v1.1 it might be a relief to know this wireless card worked perfectly right after the install and required no extra drivers or kexts to function OS X recognized it as an AirPort card)

 

Those should be all the options you need to worry about. But like I said a few times already, if there is anything special about your GX620 you might have to enable other options, it just depends, it couldn't hurt to post questions on this topic and hope other users can help you out

 

Step 4 -

After the install it should reboot by itself. I just let it load the iAtkos disk again because i wasn't paying attention and it stayed at the grey loading screen for about 10 mins until I decided to restart the computer manually.

When it restarts just pop out the DVD and let the Chameleon 2 bootloader do it's thing.

 

NOTE: If OS X is trying to load and you get the dreaded cirle with a slash (the do not enter sign) over the apple logo just restart the computer. I noticed if I restarted it a couple times it would work the 2nd or 3rd time. If you restart it 10 times and it still doesn't work obviously you need to start all over again. It sucks, but it took me 3 or 4 times installing OS X before I got it right. (I guess the whole idea is if you enable too many options or too little options it won't work, just try to stick to what you know you need)

 

Step 5 -

If all goes well OS X should ask you some computer setup questions, try avoiding any options that will annoy you, like Apple asking if you wanna receive newsletters blah blah blah, no one likes newsletters. I put fake info for the registration. Ex. First name: T, Last Name: X, Address: 100 Street St, City, CA etc etc. Also avoid any options that includes you sending information to apple over the internet, after all iAtkos is a bit sketchy to begin with.

 

Step 6 - SOUND

YOU CAN SKIP THIS STEP IF YOU DOWNLOAD THE ATTACHED FILE

Ok, so I will just upload the patched AppleAC97Audio.kext to make things simpler but just incase you're reading this and the file is no longer available I will explain how to add an ICH7 section to the version you can find floating about the net.

 

1. Find and download AppleAC97Audio.kext.zip or similar name. Use good judgement...

 

2. Open up the zip and go to AppleAC97Audio.kext/Contents/PlugIns/AppleAC97AudioIntelICH.kext/Contents/

 

3. In that folder should be a file called Info.plist, open it up in a text editor. I use Notepad++ in windows, it does a good job at not corrupting files or whatever, this isn't a lecture about text file format differences between windows and mac so let's continue.

 

4. Look for the lines that say:

		<key>ICH6 AC97 Audio</key>
	<dict>
		<key>CFBundleIdentifier</key>
		<string>com.apple.driver.AppleAC97AudioIntelICH</string>
		<key>ICH Type</key>
		<integer>6</integer>
		<key>IOClass</key>
		<string>AppleAC97AudioIntelICH</string>
		<key>IOPCIPrimaryMatch</key>
		<string>0x266e8086</string>
		<key>IOProbeScore</key>
		<integer>10000</integer>
		<key>IOProviderClass</key>
		<string>IOPCIDevice</string>
	</dict>

You're going to want to make sure that right under it there is another entry that goes like this:

		<key>ICH7 AC97 Audio</key>
	<dict>
		<key>CFBundleIdentifier</key>
		<string>com.apple.driver.AppleAC97AudioIntelICH</string>
		<key>ICH Type</key>
		<integer>7</integer>
		<key>IOClass</key>
		<string>AppleAC97AudioIntelICH</string>
		<key>IOPCIPrimaryMatch</key>
		<string>0x27de8086</string>
		<key>IOProbeScore</key>
		<integer>10000</integer>
		<key>IOProviderClass</key>
		<string>IOPCIDevice</string>
	</dict>

If not... then you're gonna wanna paste it in there, because inserting that in there is all you need to do to patch the file. Make sure you save it so that the changes you just made are permanent. Now we can move on to actually installing this ugly kext file and give you some audio output.

 

Step 7 - Install AppleAC97Audio.kext

NOTE: The app "KextHelper" was no help to me, it gave me the dreaded DO NOT ENTER symbol over the apple logo when I restarted my computer... just take the extra ten mins to do it manually, it might end up saving you an hour or so.

 

1. Copy AppleAC97Audio.kext to /System/Library/Extensions

 

2. Open Terminal.app:

 

3. Type these commands carefully:

sudo -s
chown -R root:wheel /System/Library/Extensions
cd /System/Library/Extensions/
chown -R AppleAC97Audio.kext
chmod -R 755 AppleAC97Audio.kext
cd /System/Library/Extensions/AppleAC97Audio.kext/Contents/PlugIns/
kextload AppleAC97AudioIntelICH.kext
rm /System/Library/Extensions.kextcache
rm /System/Library/Extensions.kextcache
kextcache -k /System/Library/Extensions

 

4. At this point if everything went according to plan then you should be able to hear audio.

 

5. Reboot your computer (I think this is what took me a few reboots to get os x to load)

 

At this point everything should be working properly, enjoy you're new DELL OS X? HA!
