This is a good start point to understand DSDT

This is the 2nd easy-to-follow practice, after you do it by yourself successfully, you get more confidence

Most people will not reinvent the wheel, like you and me, getting a working DSDT from other DSDT master such as Madara-san in this forum, makes life easier.
Editing DSDT is a kind of dealing with makeup language, such as HTML language, remember all tags and structures is like to remember French words and grammar. - difficult, restrictive but elegant.

with a thinkpad with nvidia nvs140m recommended the dsdt of mandara san or protocolx?

I used mandara san DSDT on my T61 with nvidia nvs140m, no problem at all. you can update the Graphics Card showing string as "Nvidia NVS140M" easily.

Solve sound issue after disable IDA.

http://yaodi.zzl.org/boot

download it to your desktop. open terminal window from Application ->Utilities->Terminal
type command: input your password. hit enter button.
type command: (xxxx is the user name as you login) hide boot file: Tested on Lion, Mountain Lion, Mavericks with X61, T61, T61P, CPU T8100@2.1GHz, T7500@2.2Ghz, T7700@2.4Ghz
All works well with correct FSB values. No glitch with sound.

Geekbench 64-bit benchmark: T61p, T7500@2.2Ghz 10.9.1
with unmodified Chameleon boot loader: 3529 (low FSB, low CPU frequency)
with updated Chameleon boot loader: 3645 (correct FSB, correct CPU frequency, IDA disabled, download from above link)
with IDA-enabled Chameleon boot loader: 3739 (correct FSB, correct CPU frequency, IDA enabled)

3739 matches benchmark on MS Windows 7, but most T61, T61p experience distorted sound problem, basically IDA enabled with 800Mhz is called "overclock" for T7500. I find only one of 6 my laptops can be overclocked without sound problem. it has the fastest SSD installed which could be the reason.

jzhang18 i've used your boot file, but what is the benefits than Mandara-san boot? Anyway it's works without problems.

another question: the animations of the operating system are often slowly, is this normal?

I do not think Mandara-san's package includes any boot loader. You need to install Chameleon boot loader by yourself. either from myHack or from Chameleon Wizard, or manually install it from pkg file.
My boot file is just for replacing Chameleon boot loader. no overlap part with Mandara-san's package.

My T61p is working pretty smooth, play movie, animation very well. I tested with StarCraft II for 4 hours online. very smooth @1920x1200 low settings. or low resolution with medium settings.

Hardware -- only PCMCIA slot not recognized, all others are working
Software -- only iMessage is rejected from Apple. (For sure, Apple iMessage server check my UUID, after I login for one second, I can see all my friends list there, but then the server kicks me out )

Whoa! Your bootloader is works perfectly! I do recommend using it. If you don't mind, it will included in my upcoming full package, containing updated DSDT, kexts and other useful tools.

iMessage CAN BE fixed! It works for me on 2 T61p's, with separate phone numbers.

Sure, please include it into your full package, so more people can easily find it from your first post in this forum.

Also, please describe more detail of your steps to fix iMessage issue.
I saw some fix and solution, but it is not doable for everyone, (someone reports working, some not).
http://www.tonymacx86.com/general-help/ ... ssage.html

Have a X61T. I used those files for working PCMCIA with a SERITREK SATA2 CONTROLLER CARD. In BIOS i changed SATA settings from AHCI to compatible to get sleep working.

http://www.sendspace.com/file/5he533

hope it works @ T61 too...

PPS: i already wrote jzang18 for a reup of the boot file. Could anyone of you send me that file @ hallo (at) alex-richter.de?

Can someone please reupload the modified bootloader for correct FSB?

CoBrA2168 wrote:Can someone please reupload the modified bootloader for correct FSB?

Sure, I will upload the boot file tonight, (I did not notice, the link will be deactivated after a while, not a big deal )

Great thanks. I'm actually running a T61 with the T9500 CPU. I've experienced this problem for over a year now, where clock speeds are reported at 200MHz lower than expected. This is great that you finally found a fix.

However, I might still have an issue. My T61 has the X3100 video chipset, so I'm unable to natively run Mountain Lion (or Mavericks for that matter). As an alternative, I'm running a program called MLPF (google it) to run a "hacked" 32-bit version of Mountain Lion.

I've found that for whatever reason, the only Chameleon that works for me is 2.1 r2069. Higher revisions do not boot for me (I'd have to check again tonight to see exactly why). Would it at all be possible to apply this fix to that revision of Chameleon?

Thanks.

My old site is down to maintenance mode, I tried to upload my file a couple of times in 2 days, no success.
So I start to use this one:

Sorry for the delay.

Wow, it worked! This is great, thanks!!

I am studying VoodooHDA source code, I try to figure out why IDA (Intel Dynamic Acceleration) cause sound choppy. I still hope I can fix VoodooHDA source code to work correctly with IDA.
If I can succeed with that, then I do not need to disable IDA, only correct the wrong FSB frequency.
That will be called a perfect CustomMAC on T61(p), Performance will beat a real Apple Book Pro with the same CPU model! Because middleton bios enable IDA on both cores. I really do not want to lose that feature.

This is AD1984 sound chipset design comes with T61(p)
http://www.hardwaresecrets.com/datasheets/AD1984.pdf

The most important part mentioned here:

FEATURES
FOUR 192 kHz DACs/ADCs
Two independent stereo DAC/ADC pairs
Simultaneous record of two stereo channels
Simultaneous playback of two stereo channels
Independent 8, 11.025, 16, 22.05, 32, 44.1,
48, 88.2, 96, 176.4, and 192 kHz sample rates

To my feeling, when IDA enabled, after I correct the Base Bus Frequency to 200Mhz. The high sample rate becomes greater than 192 kHz! then AD1984 DACs/ADCs chip cannot handle that. create distorted sound wave spectrum.

When using unmodified Chameleon boot loader, Base Bus Frequency is 182Mhz to 185Mhz, the highest sample rate is lower than 192 kHz, AD1984 DACs/ADCs chip can handle that without any problem.

When using my modified Chameleon boot loader, Base Bus Frequency is 200Mhz, IDA is disabled, the highest sample rate is just equal to 192 kHz, AD1984 DACs/ADCs chip still can handle it just right.

Above is just based on my assumption, I will take some time to prove it. If that is correct. Then I can fix it in VoodooHDA source code.

On the T61 sound has been crippled!
Recording via Stereo Mix has been removed (hardware).
That may be one source of your problem.

It's not just voodoohda. I've tried an external sound card (supported natively) and sound was also have this cracking on that too!

Anyone tried 10.9.2? Sleep is not working for me now! Trying to find a solution...

Madara-san wrote:It's not just voodoohda. I've tried an external sound card (supported natively) and sound was also have this cracking on that too!

AppleHDA and VoodooHDA is based on same logic on set sound sample rate. Because VoodooHDA is opensource, so we can change it. test it.
Very limited way to patch AppleHDA.

Madara-san wrote:Anyone tried 10.9.2? Sleep is not working for me now! Trying to find a solution...

updated to 10.9.2 on T61 14 inch and T61p 15 inch, same issue as yours, cannot go to sleep.

But more detail I observed: using AppleACPIFlatform.kext in S/L/E (comes from 10.9.2), remove patched AppleACPIFlatform.kext from E/E, sleeping is OK, but wake-up with dead USB.

Good luck with fixing VoodooHDA. I am running Mountain Lion 10.8.5 (using your latest bootloader with IDA disabled) and would be willing to help test when you come up with a new kext.

Hi Madara-san,

Thanks very much for your Extra folder...
The install of Mavericks 10.9.1 and then upgrade to 10.9.2 could not have been easier.

I am wondering if you can help me....
The keyboard on the T61 is not working correctly... I am trying to type ` or ~ but I get something that looks like a $
Is anyone in this forum topic getting the same error??? The keyboard is somewhat out..
I work a lot on terminal and not being able to type ~ is quite frustrating (workaround is an external usb2 keyboard but that
defeats the purpose)

Cheers

Hi everyone!

Thanks for these wonderful forums! I have a collection of T61, T61P, X61 and X61t thinkpads that run various versions of OS X (partial list in signature). They are working well, in a big part thanks to reading these discussions and using your kits.

I plan to post and contribute here. But for now, just wanted to say hello and thanks.

Having those keys mis-mapped is a common issue on most hackintosh laptops... not only lenovo. Do a google search, there are forums that suggest ways to fix it.

Until then as an easier workaround, you can use Keyboard Viewer to type the ` and ~ characters. It's less bulky than plugging in a USB keyboard.

(edit) This app can fix it,

(More edit)
Here's how to use the app:

Hi JaavrOS,

I did use the Apple Keyboard Viewer to do just that. Although it works, it is a bit inconvenient though...
Thanks very much for the link to the KeyRemap4MacBook... i appreciate that very much.
Have a good day

No problem. Actually, I only just found this app tonight while looking into your question. It's an interesting app, I'm exploring it to see if it can create even more features for us.
The author also has another app, designed specifically for PC keyboards. But I haven't installed that one yet.

I just checked on my T61P, it doesn't have that issue with the `and ~ characters. But my X61 Tablets did have the issue (they use different kexts).
So, if you have the right keyboard kext, you won't have that issue, and won't need to use that app. Just letting you know.
I'll upload my keyboard kext when I figure out how to put uploads here (I'm new on this forum).

(edit: Check out RehabMan's Voodoo PS2 kext. The Link is below)

Hi JaavrOS,

Yes you are correct. I have Thinkpads x61 and x300 during the day that i hacked it for Snow Leopard 10.6.8.
I was getting the same issue but someone in the forum had a fix(kext) for it. I don't have the link now.
I stop using them as hack machines since Mountain Lion because the Intel GMA950 and Intel GMA x3100
are only 32-bit graphics cards and hence not supported when ML went 64-bit.

Yes do let me know when you have uploaded your kext in this forum. For the time being the KeyRemap4MacBook
seems to work fine. All I had to do was select Don't remap external keyboards in the General Section and
select Section($ or what looked like a double S) to backquote(`) in the change Section($) key under the International
Keyboard and ISO Keyboard Users. That did the trick and I am now back to normal for that key

Cheers

Try RehabMan's Voodoo PS2 kext...

https://bitbucket.org/RehabMan/os-x-voo ... /downloads

note: the kext from 2014-0121 worked better for me (the second on the list). The newer kext (2014-0224) had a strange issue with double-clicking sometimes.

Please try this -
http://www.tonymacx86.com/customization ... tly-2.html
It improve the performance for Intel HD Graphics card (such as x3100 in X61) , also Nvidia graphics card (used in T61 and T61p)
It makes windows popup and switching much smoothly. From "About this Mac" to show "System Report", just watch "Profiler Windows" showing up.
Recommended for everyone.

Do you mean this --> BeamSyncDropper2_v2.zip ?

Sure I'll try it out!

Any news about the sleep problem with 10.9.2? I figured it out that it's not a DSDT-related problem. And deleting the AcpiPlatform.kext is not a good idea, because it brokes USB after sleep, and the moon stays lit. :/ it's a shame Apple did it to us, I'll wait until 10.9.3 for a solution....

What causes the problem with 10.9.2? The kernel? Or some updated extensions?
