Partition your hard drives appropriately, if you have XP installed on one then a dual boot is incredibly easy. Just google a guide on how to do this as it is a generic process.
Start off by downloading the TOH RC2 version of Mac OSX 10.5. This can be found on your favourite torrent site and insure that it is the "intel" version that you are downloading.
Next, find a single layer DVD-R/RW and burn the ISO file. IMPORTANT - MAKE SURE TO SELECT THE LOWEST POSSIBLE BURN SPEED AS OTHERWISE YOUR DISK WILL FAIL THE DISK CHECK.
IMPORTANT - BEFORE YOU INSTALL MAC OSX FROM THE TOH DISK, MAKE SURE THAT YOU HAVE YOUR MAC CONNECTED TO A SEPARATE MONITOR VIA VGA FOR THE WHOLE INSTALLATION, WITHOUT THIS ADJUSTMENT YOUR INSTALL WILL HANG ON A BLUE SCREEN AND YOU WON'T GET YOUR BEAUTIFUL HACKINTOSH.
When you turn on your Inspiron 1300, keep tapping F12 as you boot. This will open a one time boot loader. Insert your TOH RC2 DVD and select your DVD drive to boot from. When the CD is booting you will get an option to boot, or to press F8 to specify startup options. Keep tapping F8 and when you get the chance, type the following:
-F -X -V
and press enter.
Wait for the magical lines of scrolling text to complete their work. You will get many "suchandsuch failed" and "somethingorother error" lines but just ignore them, it's not a Mac, so don't expect it to act exactly like one under the hood.
If you've accurately followed the instructions above the installer should start and the boot screen should appear.
Select your language and then wait the the taskbar at the top to launch. When it has, click on utilities and open "disk manager".
Select your disk from down the side of the window. Then from the drop down box in the middle of the window change the format to "mac os extended (journaled)" and click erase. Make a note of the name of your installation drive as it will be important later.
Quit the disk manager and follow the installer. When you get to the final screen just before you click "install" click "configure" and deselect all the options available. Now press install and let it do its magic...
When the installation is complete, reboot the computer and leave the disk in the drive. Re-load the Mac installer and click on utilities when you get the chance. Select "terminal" from the menu and load it. Type the following code:
The volumename is the name of the Disk you have installed Mac OSX onto. This is case sensitive, so type it wrong and nothing will happen. When this is finish press CTRL+D and then restart the computer, this time without the disk. You will still need to keep the extra screen attached because we haven't patched the drivers yet.
Mac OSX should boot now, and if you tap F8 on boot you should get an option to boot your previous operating system, XP works perfectly as I am on a dual boot whilst writing this :-)
When it's booted play around with it for a bit and then get on with the driver fix. You need to download the program "Kexthelper" from www.cheetha.net. This installs the .kext files that we need for the Quartz Extreme graphics. Download the two .kexts from the links on this post (thanks to mercurysquad for his tutorial): http://www.insanelym...howtopic=141549
Install kexthelper and open it. Drag and drop the two files you downloaded into the program and press "easy install". Type your password and wait. It should be successful and if so, reboot your hackintosh.
IMPORTANT - YOU MUST PROPERLY REBOOT BY PRESSING THE APPLE LOGO IN THE TOP LEFT OF THE SCREEN AND SELECTING RESTART. IF YOU DO NOT DO THIS YOU WILL HAVE GREAT PROBLEMS BOOTING.
You will get a message saying it must edit something (can't remember now) and just press ok. When it turns off, remove the other screen and turn it on. It should now work with no jumper and full quartz extreme.
To fix the sound you must download a copy of AppleHDA patcher 1.20. Do a google search and you'll find it in 5 mins or so. Download and install the program, and drag the installed program icon onto your desktop. Now download the file attached to this post (Sigmatel9200.TXT) and save it to your desktop. Now drag the text file onto the AppleHDA patcher icon and it should begin to patch it. Insert your password when prompted and wait for it to finish. When done, restart your hackintosh PROPERLY BY CLICKING THE APPLE BUTTON IN THE TOP LEFT AND SELECTING RESTART. It will give you another message and reboot, when it reboots, your sound card will be detected and you can configure it from system preferences.
That's pretty much it! If you need any more help then message me and i'll try to lend a hand. I spent ages working this out (forgive me if its newbish but i'm only 14) and would like to save others the time and hassle. ENJOY YOUR DELL HACKINTOSH!!!
