Note: This method works for all versions of Leopard and all distro’s used to install OS X (iPC, XxX, iDeneb, Kalyway, etc.)
Lately, many people have been asking about sleep tricks and dsdt.aml’s and instead of Copy & Pasting the same text over and over again, I figured I would put all the information in one central location (kinda like the whole point of this website).
For starters, the Sleep Trick and the “Alternative to Sleep Trick” are things of the past. Both of these “tricks” are now practically useless because they have been replaced by the much more reliable dsdt.aml. A dsdt.aml is a file that holds the information about a lot of your hardware. It generates the information from your system’s BIOS, thus making it very reliable and almost fool proof. One of the things that the dsdt.aml will read is the information about your graphics card which is why it becomes so useful to Inspiron 1525 owners. When you have a proper dsdt.aml in place, your graphics card works as if it’s native to the OS. The screen automatically works and displays the login screen after booting into OS X, resolution change works fine, and games that play in fullscreen can actually be played because they can be seen on the screen.
A dsdt.aml can be generated for your system with the check of one box when installing OS X from either XxX 10.5.6 or iPC 10.5.6. This is great for people who are installing the OS for the first time or are reinstalling, but what if you already have a working install? Previously, the only other option was to run DSDT_Patcher which didn’t always work. Instead, you can use a method that works 100% of the time, take about 5 minutes, and requires no more than 10 mouse clicks.
Before I tell you what the method is, I want to state that you must be running the latest version of Chameleon for this. The latest version along with instructions on installing it can be found here.
You must also have either the iPC 10.5.6 PPF5 install disc (must be PPF5) or the XxX Rev1 install disc. Once you have both of these things, go ahead and boot from that DVD. Then hit ok/enter to all the crap that you have to until you get to the screen asking you where you would like to install to. Choose the partition that you currently have OS X installed on. Then on the next screen hit the customize button to choose what you would like to install. Now this is where the instructions differ a little bit.
If you are using XxX- When you get to the screen asking you what customizations and drivers you would like to install, uncheck EVERYTHING (including “Essential System Software”) except for “DSDT Patcher” which can be found under the “Optional Bootloaders” section.
If you are using iPC- When you get to the screen asking you what customizations and drivers you would like to install, uncheck EVERYTHING (including “iPC OSx86 10.5.6 Base System”) except for “Patch DSDT” which can be found under iPC OSx86 10.5.6 Intel AMD SSE2 SSE3/Fixes and Patches/DSDT Patches/
After following the appropriate instructions, you should now have a dsdt.aml installed on your system and the change should be evident upon your first reboot.
