In Topic: Modified BIOS to get all cores working

01 August 2008 - 12:17 PM

Well, I guess the title says it all, after spending a lot of time reading Documentations, Specifications, Forums.. and hunting for testers :P , 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:

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:

Scope (_PR)
					Processor (P001, 0x01, 0x00000810, 0x06) {}
					Alias (P001, CPU1)
Scope (_PR)
					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 PM me post your request here, included with:
  • a direct link to the BIOS file,
  • your PC specs (CPU, Chipset and Graphics Card),
  • and a description of the issues.
Don't PM me with requests, post them in this thread.

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 :) .

Hi there,

I'm trying to mod the BIOS of my laptop, a HP nc6320, because only works with one of the two cores and I have to put cpus=1 in the boot.
So when I saw this post I thought I had the same problem.

Well, I have installed a Linux in my laptop to dump and disassemble the dsdt with acpidump and iasl, the thing is that I haven't found anything like the example above, you can check the attach file.

I don't know how to solve the cores problem if it's not of the dsdt, any suggests??

I attach my dsdt.

Thank you so much.

Hi Kabyl!!!

First of all, very nice work you're doing...

I have a hp nc6320 laptop and i have installed a Leopard 10.5.2 on it but only works if I disable the dual core option in the BIOS or boot flag cpu=1

Here is the link to the BIOS ftp://ftp.hp.com/pub/softpaq/sp38501-39000/sp38743.exe

The nc6320 has a t5600 core 2 duo processor and a Intel GM945 Express Chipset.

could you mod the BIOS o tell me how should i do it??

Thank you so much in advance.
