Weird LocalApicId=N order

This is what I get on my desktop hack with an Intel quad core CPU:

 

AppleACPICPU: ProcessorId=1 LocalApicId=0 Enabled

AppleACPICPU: ProcessorId=2 LocalApicId=1 Enabled

AppleACPICPU: ProcessorId=3 LocalApicId=2 Enabled

AppleACPICPU: ProcessorId=4 LocalApicId=3 Enabled

 

And this on my HP notebook (see sig):

 

AppleACPICPU: ProcessorId=1 LocalApicId=0 Enabled

AppleACPICPU: ProcessorId=2 LocalApicId=1 Enabled

AppleACPICPU: ProcessorId=3 LocalApicId=4 Enabled

AppleACPICPU: ProcessorId=4 LocalApicId=5 Enabled

AppleACPICPU: ProcessorId=5 LocalApicId=0 Disabled

AppleACPICPU: ProcessorId=6 LocalApicId=0 Disabled

AppleACPICPU: ProcessorId=7 LocalApicId=0 Disabled

AppleACPICPU: ProcessorId=8 LocalApicId=0 Disabled

 

I already removed four extra/unused Processor (CPUn, ...)'s in my DSDT's _PR scope so that should be fine I guess. The question now is: How do I solve this problem? What do I have to do to prevent the last four from showing up?

 

Also. Is this somehow related to the cpus=n boot option?

 

Cheers,

 

Sam.

Sweet. I found something. It's the fault of my HP notebook's stupid BIOS (bad apic.aml). Here's a snippet of the original dump (the most important bits):

I will remove the last four, unneeded blocks and change the order, and fix the "Table Length" to see what gives.

Another update. Here's the new / patched version of apic.dsl:

It was surprisingly easy. Had to download a copy of iasl after I made my changes. Compiles fine now. Great.

 

Next step is to inject my modifications with a capable /boot loader. Going to try out master chief's work first. Will update when I get it to work.

HP laptops seem to have tons of ACPI issues.

 

Try Chameleon 2.0 RC5, with your original DSDT processor scope and without loading your modified APIC.aml.

If you're using an older bootloader you might want to go through the thread first to see what you need to delete from/add to com.apple.Boot.plist.

Add wait=y to com.apple.Boot.plist to see if things are working better.

So i noticed.

Thanks. I'll give it a try... after I found out what com.apple.Boot.plist options I need. Dazzling.

I am currently using Revolution (by Master Chief) which itself is pretty old by now, but I love its lack of options to mess with. I mean I can replace my /boot with a newer one. Sure. But all these options and additional files is what is keeping me from doing so.

 

Edit: Messing with the order resulted in this error on my desktop hack.
