Beware using other people's DSDT
Many newbies don't understand that you shouldn't be using DSDT's generated on other people's computers. I think everyone knows by now that you shouldn't use one from a different make and model, but many noobs assume that one generated on the same make/model is okay.
It ain't.
A DSDT can be very system specific. For example, my DSDT has this code:
Code:
OperationRegion (GNVS, SystemMemory, 0x7F697DBC, 0x0100)
But another one (also with 2GB) has this:
Code:
OperationRegion (BIOS, SystemMemory, 0x7F7AE064, 0xFF)
While one with 1GB may have this:
Code:
OperationRegion (BIOS, SystemMemory, 0x3F7AE064, 0xFF)
If you use one with an incorrect memory specification, you could get all sorts of strange symptoms.
So don't share needles, err... DSDT files. Make your own.
