i am using an T61P with Nvidia Quadro FX 570M and DVI is still not working with this DSDT. Do you think there will be any solution? VGA is working, but not very good for my Display with 1080. Booting with DSDT=No works with DVI, but If i use this Flag there is no shutdown and many other Problems.

Thank you for your help!

To my understanding , Nvidia Quadro FX 570M supports only 2 monitors, if VGA is working, then DVI is disabled, (vice versa). I might be wrong.

when "Booting with DSDT=No works with DVI", Did you test both VGA and DVI with 2 monitors? if both are working at the same time. then there might be a solution from DSDT. my original thought is wrong.

Hey madara-san,

you are right: 2 Monitors max. If i use your dsdt and attach a VGA, anything is working. Detach the VGA and attach DVI, the Thinkpad-LCD goes black (Backlight off). After detaching the DVI, Backlight of Thinkpad-LCD is on.

I received another DSDT from different Forum. This DSDT run´s with DVI. But Sleep is still not working: There is no USB after sleep...

I ask in the other forum, if it´s allowed to upload the DSDT

thank you very much

I have Advanced Dock and NVIDIA GT 640 2 GB card, But I cannot make it working. Do you use DSDT or not while putting on Advanced Dock? Any change in BIOS settings?

I used DSDT=No
No changes in Bios-Settings

Without DSDT, 2 major things you missed, Brightness Control and Cooling Fan Control. (also lose these features: some keys mapping, accurate ACPI table and some cosmetic descriptions in System Profiler) .

But you get more flexibility with varieties of peripherals, such as working with Advanced Dock.

Did you monitor your CPU temperature and frequency stepping without DSDT -- this is my most concern (running something heavy to torture CPU for about 2 hours, I hope it will not be overheated.)

Just one more reminding: NullCPUPowerManagement.kext is required when DSDT=No, NullCPUPowerManagement.kext should be removed when DSDT=Yes

The one mayor problem is that I don't have and advanced dock nor any dock for my T61p. So I need to know what are the hardware ID's for the dock. Please try DPCIManager, or IoRegistry Explorer and upload a dump with and without DSDT.

Posted: **Fri Apr 18, 2014 10:51 am**

Hello madara-san, jzhang18 and anyone else,

i don´t know how to upload files here: I merged two DSDT. Your DSDT from your new package basically with a few lines from different DSDT (with working DVI). The result is an DSDT with working DVI and all the benefits from your´s.

Anyone interested in this file?

Sleep works! Mode 0 A

I will use DPCIManager to make a dump file for you. I have one, installed with NVIDIA GT640 2GB card on it.

Really nice work! I would like to try your DSDT. I will PM you.

10.9.1 installed in Advanced Mini-Dock. Bios Settings changed before installing: Display DVI+LCD (ThinkPad). But i don´t know if its really necessary to install with Docking-station. Everything else unchanged.
Installing without any problems and both Monitors working during Install. 10.9.1 MyHack and madra-sans new Package. After Install, if have changed the DSDT to my dviDSDT and i installed cuda Drivers for Mac

Shutdown the T61. Put it in de Advanced Dock and boot the System. It is working for me.

Posted: **Sat Apr 19, 2014 2:59 pm**

jzhang18,

maybe you have to disable Legacy-Devices in Dockingstation (Bios-Settings) and install cuda drivers from Nvidia Website

Posted: **Sun Apr 20, 2014 4:03 am**

DSDT=Yes (both DSDT´s are working I think, ecxept VGA/DVI). My dviDSDT is working with DVI.
Bios-Settings: Legacy Devices in Dockingstation disabled, Power Maximum Performance all Settings, Display Settings: Thinkpad Display and not tested with attached second Monitor (if you want, i can test this).
Install cuda drivers from Nvidia Website.
Luxmark allows different modes, only Luxball runs with internal Graphics. GT 640 increases score Factor 1:10 (here is the only one lane PCI-E not very important, OpenCL test)

Posted: **Sun Apr 20, 2014 4:48 am**

https://www.dropbox.com/s/zp19d7uivfhwvah/dviDSDT.zip

Installed with Myhack and 10.9.1 from Scratch with madara-san EXTRA2 Package on GUID-Harddisk. Installed with mini-Dock and attached DVI-Monitor (biossettings: Display DVI + LCD, disable legacy devices on Dock, Power maximum performance). After Install i changed the DSDT with my dviDSDT. That´s it. If you want to test the Cuda-Performance, you have to install the cuda-drivers for Mac (Nvidia Website) and you can use an external Graphicscard in advanced Dock (Nvidia GT640 with max TDP 40 Watt, because this is the limit for the Card´s inside the Dockingstation. If there is more power consumption, the dock stops working).

sleep: okay
close lid: okay

i can´t find anything that is not working: thank you, madara-san

Further Setup: I had to copy the Mac-Partition from GUID-Disk over an existing partition (HFS+) on my SSD (with hdclone running from Win7 System) . So i`ve got a dualboot-System with chainloading from win7 Bootloader:

-first partition for 100 MB system (win7), second for win7, third for User-Data and last partition for Mac OS X and chameleon boot loader without any bootflags

I use IORegistryExplorer 3.0.2 to dump the IO information, (http://www.osx86.net/files/file/3600-io ... yexplorer/)

First I use Sieglinde Festkochend's DSDT.aml, boot with Advanced Dock, dump the file, then boot without Dock, dump the file. zip 2 dump files as this one (http://yaodi.zzl.org/DSDT.zip)
Second, without DSDT.aml, also dump 2 files, (with or without Dock). zip those 2 dump files as the 2nd one (http://yaodi.zzl.org/NO_DSDT.zip)

My test machine is T61 (T9300 NVS 140M 128MB) .

With Sieglinde Festkochend's DSDT or No DSDT, Dock DVI works for both cases. Madara-san's DSDT shows dark screen when putting on Dock.
"Disable/Enable Legacy-Devices for Dock in BIOS" both seem OK. But I disable it in above test cases.

Posted: **Mon Apr 21, 2014 3:45 am**

Dark screen means backlight off, i think, if a dvi-Monitor is attached. VGA is working well with madara-san´s DSDT.

jzhang18, what´s about sleep and close lid with different DSDT´s? With dviDSDT both is working on my FX 570M 8889-CTO

Sleeping works for 10.9.1 not 10.9.2, because patched AppleACPIPlatform.kext only works well in 10.9.1.
with vanilla AppleACPIPlatform.kext in 10.9.2, sleeping works, but wake up with dead USB.

Why is "T9500 cpu running @ 2400 Mhz" , Did you use my boot in Page 5? I fixed Chameleon boot loader with correct FSB and CPU Frequency.
MAC has lower OpenGL benchmark than Win7, it seems always true.

When I insert Nvdia GT640 2GB card into Advanced Dock, among (5) T61, T61P machines, only one T61 14 inch (T8300 @2.4Ghz ) works, all rest cannot even boot. I guess Advanced Dock does not have enough power to drive them! -- noise come from the fan becomes so loud, I will change the fan with some quiet one.

Levono does not even support Advanced Dock technically.

Posted: **Mon Apr 21, 2014 3:36 pm**

-max TDP for Graphicscard in Advanced Dock is 40 Watt. Maybe your Card with 2 GB has more TDP. I choose my Card, because it has exactly 40 Watt TDP. If the Card tooks more electricity, the Dockingstation stops working immediatly

-I tried to use your boot, but i can´t manage it. Only in one case i saw 2,6Mhz in Hardware Monitor. I don´t know the problem, maybe it´s my chainboot an i try it once more with the GUID-Harddisk.

-The noisy fan is well known in the german wiki. It´s not easy to open the Dockingstation. Maybe you find some information here in german

http://thinkwiki.de/ThinkPad_Advanced_Dock

and here

http://thinkpad-forum.de/threads/63478- ... k-%F6ffnen

with some pictures. I needed 4 hours to install a new fan and electronic fancontrol... You have to know, that the external card has only 1 PCI-E Lane. It´s enough for cuda and openCL, but not for gaming.

Posted: **Mon Apr 21, 2014 4:20 pm**

Thanks for the information, need to find some free time to do that. I bought the silent fan for replacement a while ago. just feel too busy to do that.

The easiest WWAN setup -- I found.

The WWAN card I want to choose -- supports both CDMA and GSM, supports HSPA+ 21Mb (not HSPA 7.2MB), under $30. Vender supports Mavericks

Then I found this one -- HuaWei EM820U (http://www.amazon.co...d/dp/B00AA6O44C)
Vender software -- http://consumer.huaw...8098&pro=EM820U
HUAWEI_DataCard_ClientSoftware_MAC-V200R003B015D02SP01C983(for Mac OS 10.9)

Installation and setup is easy, Release the screws from the back, remove the keyboard and palm rest bezel. Insert EM820U, connect red line to M (Main) connector, blue line to A (Auxiliary). put everything back. download and run package of

HUAWEI_DataCard_ClientSoftware_MAC-V200R003B015D02SP01C983(for Mac OS 10.9). it will install MAC OSX driver for EM820U and an application called Mobile Partner.

After reboot, there is new PPP device based on HuaWeiMobile-Modem is added into System Preferences ->Network. I can connect to T-Mobile 3G network directly from there, or using Mobile Partner, both work for me.

Under USB, I found HuaWei EM820U, but under WWAN, there is nothing.
So far, everything is straightforward, no tweak.

If your T61(p) is WWAN upgradable (WWAN antenna is installed). then you can use 3G on Mavericks

Posted: **Wed Apr 23, 2014 9:50 am**

Patch CellPhoneHelper.kext is really easy, because Mavericks supports "0x12D1/0x1446 Huawei E367"
Huawei E367 (USB-Modem) and Huawei EM820U (PCI-Card modem) use the same chipset: Qualcomm MDM8200A
So just copy the block of "0x12D1/0x1446 Huawei E367", rename as "0x12D1/0x140C6 Huawei EM820U", and update "idProduct" to "5132" from "5190" --done:

Hello jzhang18,

you posted already some geekbench results. Which Version of geekbench is running on your thinkpad? I want to compare your results with mine. My results on geek bench 3 64bit is 1447single and 2617multi and i have still problems with your boot an d my t9500

Thanks

There is big vulnerability found recently in OpenSSL/SSH, both Microsoft and Apple depend on it. They start to patch their OS almost the same time for it!

I still use old Geekbench v2.3.4. what is the issue with the boot file? -- I want to know, it should fix T9500 from 2.4Ghz (wrong) to 2.6Ghz.

What sort of software you are using to read out the current frequency of the cpu? HWMonitor?

Yes, I use HWMonitor. I saw these information which I added into boot loader.

Code: Select all

IDA is detected as enabled in BIOS
We disable IDA during Chameleon booting...
Correct wrong FSB frequency due to IDA

But it should show:
max: 13 current: 13
CPU: TSCFreq: 2593MHz
CPU: FSBFreq: 199MHz
CPU: CPUFreq: 2593MHz

Let me check my code to see anything I overlooked.

I have laptop with Intel T7500, T8100, T8300, T7700, T9300, Frequency from 2.1Ghz to 2.5Ghz

I notice your bdmesg showing
CPU: FSBFreq: 185MHz
That is out of calculation range of my boot loader. Now I correct that (maxfsb = 186000000 from old value 185000000) . recompile it with XCODE.

Code: Select all

				if ((p->CPU.Family == 0x06 && p->CPU.Model >= 0x0e) || (p->CPU.Family == 0x0f)) {
					/* On these models, maxcoef defines TSC freq */
					maxcoef = bitfield(msr, 44, 40);
					if(ida == 1)
					  {
					    DBG("IDA is detected as enabled in BIOS\n");
					    msr_ida = rdmsr64(MSR_IA32_MISC_ENABLE);
					    ////msr.hi |= (1 << (38-32));  /*|= (1 << (38-32));*/
					    msr_ida |= (1ull << 38);
					    wrmsr64(MSR_IA32_MISC_ENABLE, msr_ida);
					    DBG("We disable IDA during Chameleon booting...\n");
					    DBG("Correct wrong FSB frequency due to IDA\n");
					    uint64_t minfsb = 182000000, maxfsb = 186000000;

					    if (maxcoef) {
					      if (maxdiv) {
                                                fsbFrequency = ((tscFrequency * 2) / ((maxcoef * 2) + 1));
					                  } else {
					        fsbFrequency = (tscFrequency / maxcoef);
					                 }
					    }
					    if ((fsbFrequency > minfsb) && (fsbFrequency < maxfsb))
                                            {
					      maxcoef--;
					      currcoef--;
                                              if (currcoef < maxcoef) {currcoef =maxcoef; }   
					      }
					  }
					maxcoef_o=bitfield(msr, 44, 40);
                                        currcoef_o=bitfield(msr, 12, 8);
					
				} else {
					/* On lower models, currcoef defines TSC freq */
					/* XXX */
					maxcoef = currcoef;
				}

				if (maxcoef) {
					if (maxdiv) {
						fsbFrequency = ((tscFrequency * 2) / ((maxcoef * 2) + 1));
					 } else {
						fsbFrequency = (tscFrequency / maxcoef);
                                               	   	}
					if (currdiv) {
						cpuFrequency = (fsbFrequency * ((currcoef * 2) + 1) / 2);
					} else {
						cpuFrequency = (fsbFrequency * currcoef);
					}
                                        maxcoef = maxcoef_o;
					currcoef =currcoef_o;
					DBG("max: %d%s current: %d%s\n", maxcoef, maxdiv ? ".5" : "",currcoef, currdiv ? ".5" : "");
				}
			}

I will publish the new boot loader soon.
