Hey All,

Yesterday I bought one of the latest motherboards of Asus, the P5Q3.
This motherboard has also one of the latest chipsets of Intel, P45.

Before I bought it, i did some researh but without result so I just bought it, thinking it wouldn't be that hard to get osx86 on it....
Unfortunately I am not even able to boot the install dvd or boot from a running version of OSX on a USB drive.

The boot already stops at the beginning like is showed here:


Does anyone already have more luck with P45 boards and Leopard?
Any tips are welcome!

Thanks guys.
BiTRiP

I've checked the BIOS on the new ASUS P45 based boards about a week ago, and they need a modified DSDT, I can try making a BIOS mod for you, another option is: try using an old AppleACPIPlatform kext (pre 10.4.8) like the ones used in kalyway's DVD and probably also in leo4all, you'll need to boot with cpus=1 (yes this means only one core).

But then my system will use only 1 core ?!?!?!?
I just bought a quad-core so would like to use the full benifit of it.

I will try to install 10.4.x later this night to see what it does...

BiTRiP

Just thinking out loud here... If you have to boot with CPUS=1, could you then install CHUD, and then enable the 4 cores once booted?

CPU=1 as startup-option gave no other results.
Neither old releases like 10.4.8 or Kalyway 10.5.1, it only reboots automaticly itstead of hanging but quits on some spot.

BTW: CPU is a Q9450 quad core.

BiTRiP.

Hi there, i managed to boot Kalyway 10.5.2 and install the System on my P45 Board. I needed to remove AppleSMC.kext to get it to work.

But still no boot from HDD

Will notice if i get any further on this.

Hi Kabyl,

i even tried the older *ACPI* and *APIC* kext with no luck yet

Oh, well done! So you were able to install it but after first boot it didn't boot anymore?
At least you got the install working which gives me already a bit of hope

Tonight I'm going to inspect again what will fix this problem.

Cheers,
BiTRiP

I have the same problem (my motherboard is Asus P5Q Deluxe).

I read in some forum to change in the Bios SATA RAID AHCI Mode from IDE to AHCI. Tonight I try to install without the AppleSMC.kext....

A question for IPhoneTom. What happen after you successful install Kalyway in your PC? did you lost dual boot with windows vista?

Thanks

I have three hdds, one for vista, one for osx and one for all the data used in both worlds...i boot only and always by bios boot select...

maybe the new kalyway 10.5.3 could fix the problem....

No, no first boot yet. It boots only from the install media dvd.

Just picked up an Asus P5Q Deluxe yesterday to replace my P5B Deluxe (on which I had Leopard running ).

I've tried:

- booting from the existing HDDs - No
- installing Kalyway 10.5.1 and 10.5.2 - No
- installing Leo4all 10.5.1 and 10.5.2 - No
- tried AHCI - No

Depending on which distro I used, I would get to different points in the install before it would restart my computer. Looking forward to some solution.

How are you guys setting up the BIOS?

BTW .. overclocking an E8400 and have it up to 3.7 without sweating it .... looks like plenty of room left.

There is no support for ICH10 southbridge yet.

But is it Apple that has to implement that or will it be a patch by some kind of genius?

BiTRiP

Yes, am curious too if this has to wait for Apple to use the p45 set in their hardware?

Would be nice to get the latest chipset for a hackintosh...

OK, except the audio I have a FULLY working machine on my P5Q3 p45 ICH10R mobo!!

I have to look into the audio since it's a new ADI2000B sound onboard. But rest is working fine!

See picture...its real!

Is there a good chance of the Gigabyte GA-EP45-DS4P working as well? It still has the ALC889A sound which seems to work well for Leopard. I'd rather opt P45 than the X38/X48 since Crossfire isn't critical.

This is great news! what was the trick? I am very interested in using the new Gigabyte GA-EP45-DQ6 to build some very nice workstations and a server. Teaming the 4 gbe should allow for server/client HD video workflow. Please let me know how you got P45/ICH10R working.
Thanks!

The GigaByte boards should work just fine, and I even recommend them, because they use ALC889a (0x0885 as a dev-id like in real Macs) and the RealTek NIC that is known to work OOTB..
the problem with MSI is the Processor Aliases thing in the DSDT. Now, new ASUS boards (P45 based) have this thing too, so that explains why it didn't work for BiTRiP and he had to use a modified BIOS..
I still recommend GigaByte boards..

-Kabyl

All honour goes to Kabyl who helpt me to make this possible.
He modified the biosrom and after double checking for bios backup chips, in case something went wrong, I reflashed it and could boot it from a pre-installed USB drive.

Then i installed 10.5.1 from retail dmg and upgraded to 10.5.3.
Just some minor plist edits to get all NIC's working etc and then it was done.
Fully working new system.

Thanks again Kabyl!

BiTRiP

so the only way is to modified the biosrom... not very easy for me. I'll wait an easer way....

Thank you both!! I've been wondering what kind of computer to buy so I can run vanilla, and this answers so many questions.

hi Kabyl
is possible an a modified bios for my MB asus P5Q
my bios is "P5Q-ASUS-0506.ROM"

thanks

Very cool. For my own interest, can you describe what DSDT is, why it causes problems, and what affect changing it has other than finally allowing OSX to boot? Maybe you can even describe the bios hack procedure at some point so that us interested parties could help make the modifications?
Many thanks,
genzai

Indeed, i got it to work w/ audio,network,gfx,etc all ok, but the Systemprofiler says 'Number of Processors=0', so i need to boot up with cpus=1.

Yes this is great news, any details on how to mod the bios, or what you did? I've run into the same problems with my new Asus P5Q Deluxe.

Same here. Please how did you modify your bios?
I can't use Kabyl's mod-bios as mine is already modified for Vista slic-mod.

Hi, wow great job!!
and... it would be great if you guys can explain in more detail how to get it to work on a P5Q (...and/or provide the needed bios for testing).
I urgently need a solution because my ex- P5W doesn't work anymore.

Hi there.

I dont think that matters, since you mod the ACPI AML.

I did it on my own with my MSI P45 Premium, now all 4 cores working well. And that mod is just simple

Things you need are:

- iasl Tools from Intel
- some Tool able to extract/replace parts from your BIOS (for me i used MMTOOLS, 3.19 T21fixed)
- some HEX-Editor

Steps are as follows:

1. Extract your ACPI-AML (DSDT) (uncompressed) from an original BIOS ROM File.
2. Copy the extracted ROM-Part to the folder where you installed the IASL-Compiler
3. Open your DOS-Prompt, type
to decompile the DSDT. it will write an *.dsl file.
4. open the *.dsl file with some Texteditor, remove the 4 *Alias* lines
5. go back to the iasl-folder and type
. it will compile the sources you created in step 3
6. open the resulting *.hex file with an texteditor, you just need the hex-values in each line (8 values each)
7. use your hex-editor to create an *.rom file from those hex-values
8. save the file as *.rom
9. use MMTOOLS to replace the ACPI-AML block.
10. save your BIOS & flash it. You are done!

If some of you guys need the BIOS for that P45-Board just drop me an line. Its the newest 1.1 release from today.

Have fun on your P45 Hackintosh

Hi iPhoneTom

can you modify for me my bios of p5q asus MOBO

many thanks

the attached file is the actuals original bios .

Hi m8's - i wd realy want to have a moded biso for the asus P5Q as well - please

im a newb as it comes to mod the bios but i can sure install a moded one ...

please if someone have a link to drop regarding this moded bios for the P5Q it will be greatfull !!!

thanks in advanced

Hey, there is an problem with that BIOS. Asus didnt make an ACPI AML entry (id 10h), they put it into the SLAB (id 1Bh). So it will be too dangerous for me to modify that without an Tool.

Maybe Kabyl can help you with that?

Sorry for that!

we are all hopes here

Thanks =)

@iPhoneTom
It's a pity your nice tutorial wouldn't work for our Asus mobos.

@Kabyl
Please, how do you do that? Come on, share your knowledge.

Thanks for the fast reply.

Best regards.

Bye.

Hi nusical m8, i understand from ur say that u can share info on how to do that moded bios thingy - can u please or anyone als upload a link with the bios moded for P5Q ?

thanks alot =)

Hi iPhoneTom,

Could the ACPI AML in other motherboards be an issue as well?

I have an Asrock 1600twinsP35 motherboard with a Q6600 in it, that I tried, and I could only get it to boot with CPUS=1, otherwise it stopped in the same place as BiTRip's P45 board. I also tried 10.4.7 versions of the ACPI and APIC kexts without any luck.

thanks for any thoughts

Hi.

Indeed, that could be the problem.

Asus P5Q-E here and having the same problem and here I was hopping this system would be easier to make work than my old AMD system was! Hopefully there will be another option besides modding the bios since it seems that wont work with the Asus mobos?

For those people with a Asus P5Q3 mobo, here is the patched version of the latest bios version (0704)

ATTENTION: This is NOT for the P5Q !!!!!(without the 3).


Click this link to download the file.

Enjoy!

BiTRiP

given that someone has figured out the problem, and has fixed via bios modification, what are the chances that someone will devise a method to hackintosh a P45 without modded bios? (ie: modded kexts)

Hi BiTRiP,

can you upload the ICH10r kext , because the my P5Q mobo can't recognised the serialATA
controller.

thanks.


Bye

Mine wasn't recognized either. I just edited the plist in AppleAHCIPort.kext.
Changed the ICH8R name to ICH10R (or make another enrty) and set IOPCIPrimairyMatch to match my VID/PID of the sata controller.

BiTRiP

Any chance of getting a patched bios for the P5Q-E? Or info on how to do it my self? Thanks!

I will be getting my new motherboard (P5Q-E) within the next week, so a patched BIOS or info on how to patch it would be nice for me too.
Thanks!

I'm going to get my new motherboard(P5Q-Deluxe) tomorrow also since my P5WDH doesn't work anymore
anyone can upload a patched bios for P5Q-Deluxe please

something new with the sound ?

check the site in my sig, for a modified BIOS:
P5Q-ASUS-0703
P5Q-ASUS-DELUXE-0803
P5Q-E-ASUS-0803
P5Q3-ASUS-DELUXE-0704

Wow!
Thanks Kabyl. Nice work!
Have all these BIOS mods been tested? I'm sort of afraid of screwing up my computer once I get my new motherboard.
