I see a lot of posts here that say you have to modify your DSDT.

When I installed Leopard 10.5.6 I do not remember modifying any DSDT file and
I have successfully ugraded to 10.5.7 and then 10.5.8 and the system is extremely
stable. No issues at all.

I consider myself a noob yet so bear with me.

1. Where is the DSDT file on my current system?

2. Can I use a copy of that DSDT to install Snow Leopard?

3. Where is the DSDT file that everyone says you must modify.

4. How do you modify the DSDT?

5. Is there a tutorial on DSDT modification?

6. Is there a DSDT on the Snow Leopard DVD?

7. If there is a DSDT on Snow Leopard, is that the one I have to Modify?

8. Is there a utility to display my current DSDT so I can extract info from there
if I need it?


Be gentle and thanks for assistance.

If you need to move this post to a new section, just let me know
where you move it to.
Docshadow hit on all the points, but for clarifaction (FYI if your interested), your DSDT resides in your bios. It controls specific hardware to your motherboard (onboard audio, onboard lan, cpu, usb ports, sata ports, etc). You can use a dsdt patcher to extract the dsdt from your bios (turns it into a file on your harddrive) and from there you can decompile it, modify it, recompile it and use a dsdt aware bootloader to have it "overwrite temporarily" the dsdt in bios with the modified dsdt file you have on your hd. Hope that clarifies what a DSDT is....
