If you are using the AMI tool to extract the 1b-SingleLink...., then this will work for you. If not, then you have to wait for me to get a package together with the tools. I also recommend using Winhex, it will make your life easier.

You are basically reinserting your compiled dsdt file back into the 1B file you extracted, without causing any changes to the file size. And since we are removing something, the new file should be smaller in size. You inject the file back into the original and then fill the remaining spaces with 0x00 (hex=00). (Q for Kabyl: Can we decrease the size of the dsdt section instead of filling it with 0x00?) If this does not work, then you might have to wait for the guide.

Hello Kabyl.

I'm repeating my question about modying bios for my notebook Asus F2F.
My 1st request was posted 2008.05.10. Is this possible or not?
Here again bios link for my NB:

my bad, oops

I am using an Asrock ConRoe1333 DVI/H R2.0 with a Celeron 420 (1.6 GHz single core).

In ioreg, it shows up as CPU1-CPU4 (why?).


I have to use an old version of AppleACPIPlatform.kext, otherwise the CPUs show up as "busy" in ioreg and the boot is extremely(!) slow with messages such as


Would using your file ConRoe1333-DVIH(R2.0)(2.10) allow me to use the latest AppleACPIPlatform.kext without these errors?

And how risky is using a modified BIOS? (Has anyone successfully flashed the ConRoe1333-DVIH(R2.0)(2.10)?)

I use MSI PR320 notebook.

I want your modified BIOS.

I'm Korean, so I'm not good at Engilsh.

Hi, please check my pic to see if my hackintosh is running 2 cores.

There are 2 CPU in Activity monitor but only 1 core in sys info. Kinda strange...

question for DTSu/Kabyl/someone more masterful at these low level issues than I am:

I am still struggling with being able to boot the ASUS M50SA I have with or without CPUS=1.

I have now been able to extract/replace Single Architecture Link Bios successfully for this board. I insert the DSDT compiled without the "CPU Alias" lines, flash successfully...and nothing.

It's very strange. The Leo4Allv3 disc I use can run OK, GUI works well enough, but only with CPUS=1. Once installed, nothing seems to work.

This trick isn't it for this board or isn't the only needed step maybe.

Weird, no?

Especially since this M50SA is (I believe) the same mainboard as the NVIDIA-video card version, the M50SV, which is fixed by this.

Any guesses what other things could cause the issue for an ASUS? I am stumped, just trying things like the new Chameleon bootloader, different kernels, but it feels like I'm getting colder, not warmer.

Cannot even boot WITH the CPUS=1 limiter.

Any tips would be appreciated.

Thanks

I'm really happy to ear that, there are far too much notebooks and motherboards for Kabyl to fix for ever. He's been really kind all this time, but no human can make all that work for ever.

Anyway I heard he (Kabyl) was working on a .kext that would fix DSDT problems in the same way Linux does. Any news about that?

Thanks in advance for your future guide, and thanks again to kabyl for his work and his solidarity.

Try to enable NX in BIOS. It worked for me.

Hello and thank you so much for your extra work to help so many of us.

I am trying to use an ASUS P5K motherboard with Intel E6750 Core Duo processor. Everything has been patched to work except in Apple Profiler it tells me:

Hardware Overview:

Model Name: Mac
Model Identifier: P5K
Processor Name: Intel Core 2 Duo
Processor Speed: 2.67 GHz
Number Of Processors: 0
Total Number Of Cores: 1
L2 Cache: 4 MB
Memory: 6 GB
Bus Speed: 1.33 GHz
Boot ROM Version: BOOT.EFI.V80

I believe it should state 1 processor and 2 cores.

I have attached the 1006 bios link which also adds the E6750 processor.

My MSI ms-7379 (G31M v.2) was killing me, what ever i did no way to get OS X running, after you bios version Kalyway is up running.
Thank you VERY VERY much.

Here is a guide for modifying DSDT for AMI bios. I gathered most information from Kabyl. The orginal plan was to create a nice pdf but I am unable to gather enough time to sit down and create one. So hopefully, this guide will do for now. Feel free to add other bios moding guide here.

WARNING!!! BAD MODIFICATION OF THE ROM FILE AND FLASHING BACK INTO YOUR BIOS CAN KILL YOUR MOTHERBOARD! TRY THIS AT YOUR OWN RISK! I AM NOT RESPOSIBLE FOR ANY DAMAGE!!!!!! IF YOU ARE UNSURE OF WHAT YOU ARE DOING, DO NOT TRY THIS!!

1. Download the AMI bios you wish to modify. It should have the .ROM extension.

2. Run the MMTOOL.EXE from the AMI_DSDT_TOOLS.zip
Click to view attachment
3. Click "Load ROM" and choose your bios file.
4. We are now going to extract the DSDT from the ROM. Click on "Extract" tab. Then on the list box on the bottom half of the MMTOOL, select "1B" named "Single Link Arch BIOS".
5. Make sure "In uncompressed form" is selected. Enter a filename in the "Module File" textbox and then click on the "Extract" button (For example "SingleLink.dat")

6. Using WinHex and open up the file you extract ("SingleLink.dat"). We are going to look for the case sensitive string "DSDT". There should be two instance of this in the file. We are only interested in the second instance. So search for "DSDT" twice.

7. Right click on "D" of the "DSDT" and choose "Beginning of block".

8. From this position, search for the hex string 57 41 4B 68 2E (WAKh.)

9. Right click "h" of the "WAKh" and choose "End of block".

10. In the WinHex Menu, select the "Edit" drop down and move down to "Copy Block" then "Into New File" in the new choices. Enter a file name with the .aml extension (ex: mydsdt.aml).

11. Extract iasl.exe from AMI_DSDT_TOOLS.zip into the directory where you saved the .aml file. Open a command prompt and change to the directory where you saved the .aml file. use this command line to decompile the .aml file: "iasl.exe -d mydsdt.aml". "mydsdt.aml" is the .aml you saved earlier.

12. After running "iasl.exe -d mydsdt.aml", it should generate a file name "mydsdt.dsl".

13. Now here is where we start to remove the "Alias" in the dsdt. Use notepad and open the "mydsdt.dsl" you should see lines like:


We are going to remove any line that starts with "Alias". After it is removed, save the file.

14. Here is the part where if you have problems with your DSDT, you are going to have problems. There are number of resource on google that can help you debug the issue you will be having. Hopefully, you can don't have any issues. What I would usually do is google "dsdt" and the error message that iasl throws out. Kabyl might have hint on how to recompile the DSDT while ignoring the warnings and errors.

To compile your new mydsdt.dsl use the command line "iasl.exe mydsdt.dsl".

15. After running "iasl.exe mydsdt.dsl" it should produce a file named "DSDT.aml". We are now going to inject this file back into the .dat file we saved earlier ("SingleLink.dat"). In WinHex, open the "DSDT.aml" you compiled. Press "Control A" (Select all). On the lower right hand side of WinHex you should notice a hex representation of the size of the block you have selected (For example "Size: 5AC4"). Make note of this hex size.

16. What we are trying to do here is to insert the DSDT.aml into "SingleLink.dat" without changing the file size of "SingleLink.dat". Since the new DSDT (DSDT.aml) is smaller, we can just replace the DSDT and then pad the rest of the sectors with 00.

17. Go back to the "SingleLink.dat" and hopefully the DSDT block we copied into a new file is still there. If not, then repeat steps 7,8,9 again.

18. Left click on the "D" of the DSDT in the beginning of the block in "SingleLink.dat". In the WinHex "Edit" drop down on top, then select "Fill Block". We are going to "Fill with hex values" of "00".

19. You will see "00" filled block. Your current cursor position should still be where "D" was. Now on top of the WinHex windows, click on "Position" then choose "Goto offset". Select "current position" and put the hex size that you have made a note of in step 15 in "New position" text box. Click okay, and it will take you to the new offset position. Right click on the new position (blinking cursor) and select "End of block".

20. Go back to the beginning of the block where the "D" was before you filled it with 00 and left click on that position. In the WinHex menu on top click on "Edit" and select choose "Remove". You will get a popup box saying removing the current block will decrease the file. Click "yes" to continue

21. Now, goto your DSDT.aml file, select everything in this file by pressing "Control A". Then in the "Edit" menu in WinHex, choose "Copy Block" then click "Normally".

22. Go back to the "SingleLink.dat" file, your cursor should still be where the "D" was. In the WinHex menu on top, choose "Edit", then "Clipboard Data" then "Paste". A popup window will inform you that the data about to be pasted will increase the file size. Click Ok.

23. Goto the end of the block (should end with "WAKh") and make sure there is a hex character of 2E right after "WAKh". If there no 2E, then just modify the character right after "WAKh" to hex 2E.

24. Save the file and now we are ready to insert the file back into the .ROM

25. Go back into the MMTools and choose "Replace" tab. On the list box, chick on "1B | Single Link Arch BIOS". Next to the "Module file:" textbox, there should be a "Browse" button, find the modified "SingleLink.dat". Click on "Replace" button and you should be done.

26. Click on "Save ROM" button and save to a new ROM file. Flash this ROM into your BIOS.

Kabyl, can you please mod the bios for the msi p6ngm? (ms7366)) I found a BIOS here: http://global.msi.com.tw/index.php?func=do...9&type=bios

Thanks for the help.

Hi, Kabyl! Thanks a lot for your great work.

In 26.06.08 the MSI had uploaded a new bios for MSI-P35-Neo (7360). There is a new 1.8 version there.
Could you please modify it? The previous bios, which you had modified, works fine, but sometimes it has some inexplicable issues.
All bios's settings may be reset by unknown reasons. I don't know it depends on what. The keyboard may not work in setup mode, I cannot enter the setup and so on. At least I had those troubles twice. It was resolved by the clearing CMOS. But on the whole it works good.

If you get decompile errors then use the last WAKh as the end of block.

Hope that helps.

Thank you David for help.

I shall continue search of the correct decision, it seems specifications of this part bios have changed.

Maybe the clock battery you're using is out of charge? I know it sounds stupid but that's the only thing that has made my settings die suddenly ever.

Hey kabil, I downloaded the mod.Bios from your web) ASrok wolfdale 1333-D667
How I flash the mod. Bios
From Windows ?
Do you have a guide or a step by step.
Sorry I am a noobie

THX

Thx to david_tsu guide i got finally my bios modded for working osx leopard on 2 cores

its only the dos version but it shouldn't be a problem booting with an old win98 disk or bootcd for dos into dos and start the flashing process using: "afudos P35P130M" (without "quotes")

The bios is for the ASROCK 4Core1600P35-WiFi+ - dont know if it works for the without WIFI version... but the only difference between the WIFI+ and the standart boxed version is that the standart boxed version is dilivered without the wificard for the mini slot on the board... so it should theoretically work. if someone tests it please let the others know if it works.

reports, thx, greatings are always welcome, so... dont hacitade

have fun with 2 cores

DJnEO

DISCLAIMER: i give no warrenty for misflashed boards or everything else. try it on your own risk!

David Tsu, I was following your guide to mod my bios, but when I do iasl.exe -d mydsdt.aml I get this error:



Any ideas?

@kabyl

any news on your DSDT kext? im willing to beta test it. i feel more safer on the kext than on modifying the bios.

Hi David,

Thanks a lot for your guide, it is very clear.
I own a P5Q and worked out the 0703 bios. Everything went fine, I'm just uncomfortable with the way I fixed the iasl compiling errors. I had quite a few errors about _T_0 or _T_1 being reserved words :



I fixed these by replacing every occurence of _T_0 and _T_1 by T_0 and T_1. Do you think this is correct ?

After fixing these errors, I still ended up with 6 warnings :


I haven't found any clues to clear the warnings, do these really need to be fixed ?
I'm a little uncomfortable flashing my bios, I would have much preferred avoiding these warnings.

Thanks a lot for your help.

yes, you can ignore the warnings..

Does anyone know if the bios for an ASRock 4Core1600Twins-P35 has been corrected? Either version 1.3 or 1.4.

Before I try this myself, just wondering if someone has already done this.

thanks
