, I finally got tehmachacker (thank you) to test a modified BIOS, and as expected, it worked.This is the issue that intends this mod to fix:
http://forum.insanelymac.com/index.php?showtopic=78235
Basically, what I'm doing is modifying and fixing errors in the DSDT; removing aliases for the "processor" devices, because the ACPIPlatform kext doesn't like them and treat them as other CPUs.. (it's written for Macs, and Apple doesn't use that in their Firmware's ACPI Tables, actually I don't see why we need them, well..)
I for example change this:
CODE
Scope (_PR)
{
Processor (P001, 0x01, 0x00000810, 0x06) {}
Alias (P001, CPU1)
}
{
Processor (P001, 0x01, 0x00000810, 0x06) {}
Alias (P001, CPU1)
}
into:
CODE
Scope (_PR)
{
Processor (P001, 0x01, 0x00000810, 0x06) {}
}
{
Processor (P001, 0x01, 0x00000810, 0x06) {}
}
Sometimes I have to fix more stuff.. you should know that when you try to compile your DSDT.
So if you want to get a fixed BIOS, you can
- a direct link to the BIOS file,
- your PC specs (CPU, Chipset and Graphics Card),
- and a description of the issues.
You will find some of the modified BIOSes here.
Keep in mind that I take no responsibility for a bad flash or if anything goes wrong..
NOTE: About Dell laptops, I'm still trying to find the cause of the issues, so if anyone has any suggestions, you're welcome
