Did some tests with the Kozlek's FakeSMC kext + HWMonitor app as published in Web site article. I obtained similar results as with my D630 nVidia laptop, i.e. native SpeedStep + discrete graphics card GPU monitoring. This removes the need for PState kext & launcher, IntelCPUMonitor kext; even the VoodooTSCSync kext can be removed. I've been experimenting with MBP5,1 (SMC key 1.33f8) profile to start with as it's now a known good basis to verify behaviour. Then tested iMac8,1 (1.30f1), iMac9,1 (1.30f3) and iMac10,1 (1.53f13) profiles. All give good native SpeedStep and GPU throttling between 270Mhz and 810MHz. I saw no throttling at all for GPU RAM: it's always shown at 405MHz. After thorough testing, I found iMac10,1 settings (smc-mcp/1.53f13) appeared to give best clocking results overall. FakeSMC_1.53f13.kext.zip smbios_iMac10.1.plist.zip HWMonitor.zip - - - - - - - - - - Edit #1: 15 Aug 2013 . Updated post with SMC key & SMBIOS details, kext/app versions and copies of files. Now using FakeSMC v5.2.678 (compiled 32/64bit mode).

Good, now you can do a search on NVRAM module and Chameleon version conflicts...

BIOS can't be updated from OS X. You can: - use Windows package - use DOS bootable USB key - extract .hdr file from BIOS package and use recovery procedure Do a little search (on this forum or on the greater Web) and you'll find all you need.

If you have NVRAM.dylib in /Extra/modules, remove it and try again.

Well, normally you swap discs, press F5 to refresh media list on screen, the retail DVD should appear and if you press ENTER, it should load.

Are you using a Snow Leopard retail DVD and if so, which version is it? 10.6.0? 10.6.3? I can't recall ever seeing any reference to EVOreboot on any of my previous "standard" ModCD+retail SL 10.6.3 DVD utilisation. But maybe you're using a USB key with a restored image of SL and some tuning with kexts in /Extra.

Tabernacle! That is most excellent: native SpeedStep. It's probably the result of that more recent FakeSMC that you installed. Even greater if it's also able to monitor the GT610 GPU, which it appears to.

Excellent, another to the list! Well done! What do you mean re: Sleep works "manually"? Anything that doesn't work at all?

You should try and run some unix-level commands or programs in the background whilst monitoring your CPU multipler & frequency in HWMonitor. I've got a funny feeling you've got no SpeedStep at all and are therefore running permanently at lowest multipler & frequency. For instance, run Geekbench or open up Terminal and type: yes | yes | yes | yes >/dev/null &, then click on HWMonitor to monitor CPU. If SpeedStep is indeed running, you should see multiplier & frequency go up to maximum value (in your case x9.5 and 3.16GHz) with possible intermediate variations. If you have no SpeedStep, you're CPU will be stuck at x6 and 1.99GHz. Don't trust those CPU T° either... Even at x6 and 1.99GHz, I kind of doubt your E8500 would operate at only 28°. You probably require to do some Tjmax tuning here. If you're now using FakeSMC 5.0.3x (your initial kexts pack showed older version v4.2.0), have a look at the article we've posted on the web site re: performance turing with FakeSMC and SMBIOS editing. Find the Mac model that best matches your own gear and try to edit your SMC value. If you didn't have native SpeedStep, you may gain it this way. If not, you should use the emulated SpeedStep utility that we've included in EDP (PState).

If you use tools such as HWMonitor, you would be able to monitor Temperatures + CPU throttling. You may need a FakeSMC kext that's more recent that the version you're currently using or you can try to add plugin kexts too. If you don't have native SpeedStep and/or no SpeedStep facilitator (such as PState), your E8500 CPU is highly likely to be stuck at its lowest frequency/multipler, i.e. 2.0GHz.

No harm done at all. On the contrary, you may be able to contribute to fine tune certains things. And on double checking, I don't see a specific ML bootpack for the Optiplex 755 (although it's easy enough to make one up out of the previous 2), so thanks for showing us ML runs well on that model and without a (patched) DSDT table. In fact, you even seem to have a better installation than most I've seen on this model. I'm unfamiliar with the AHCI_3rdParty_SATA + AHCIinjector kexts you use, but I guess they work together, right? Did you try at all to copy/paste the ICHx AHCI contents of the injector to the "more" regular/known IOATAFamily kext plugin? I guess the BIOS does not offer native AHCI or RAID HDD mode. Did you try to boot without NullCPUPowerManagement and do you get native SpeedStep at all? Could you confirm your Optiplex 755 model and specs? SFF with Intel E8500, isn't it?

You don't necessarily need AHCI to install Snow Leopard... You say you get a KP; what does it show in the error message? I know of issues with nVidia graphics cards on AMD machines (at least for ML), so you may be in the presence of something similar.

Hi, the Optiplex 755 has long been integrated in EDP. You can find the bootpacks at the usual place. The nVidia GeForce GT610 works OOB with Lion and ML (see post #4 here: https://osxlatitude.com/index.php?/topic/2032-dell-vostro-200/).

PCiRoot/PciRootUID=0 is default settings. Did you try with those options set to 1? Same for npci option, there are 2 possible values: 0x2000 or 0x3000.

Now that's what I call challenge! 1st of all, only real Mac systems can boot OS X CDs/DVDs directly, non-Apple systems require a bootloader. 2nd, Apple never used AMD CPUs in their products; as such, AMD-based platforms require special kernels to boot OS X. Now the question for you to resolve is whether a past or present AMD-oriented bootloader would boot on that x86 Sun workstation. Try Nawcom's ModCD. If that does not even boot, stick to Unix/Linux OS.

Sounds like a brilliant contribution, many thanks for this!

Try and re-install Chameleon on that ML partition/HDD.

Check your BIOS settings and make sure you've used the right bootpack on your installer then. Or re-make it in case it got corrupt for some reason... For Lion, I also recommend that you boot with option "USBBusFix=No".

Is that a distro or "downloaded" image you're using or a legit' Lion installer app from AppStore that you've used to make a myHack installer with our bootpack?

Having done RAM upgrades on several existing/running SL/L/ML installations, I can tell that they've always gone straight through, just as they would with Windows. Maybe your new modules are faulty, badly seated or of the wrong type. What did you put in? A RAM upgrade is normally completely transparent and without side effects. Does your D830 show the full 4GB in the BIOS Ok?

Which Lion version did you install or are you trying to install? There often seemed to be trouble with post-10.7.3 versions at initial installation, whereas it's Ok with 10.7-10.7.3 versions (that you can subsequently upgrade to 10.7.4/10.7.5 after EDP has been installed and system build done). Are you getting KP at myHack installer startup or is this happening on boot/reboot after the installation completed?

Do you have a DW530 bluetooth module installed at all? That was known to cut audio off. You could also try the patched STAC92xx kext to see if it makes any difference.

The Dell Latitude 13 has been integrated in EDP for a while now. Just follow the installation procedure with myHack USB installer + retail SL image/DVD + OSXL booptack then post-install EDP. The booptack will hopefully work for your machone, but you'll see soon enough... Your Intel wireless card will need to be replaced though; it's not supported. With a Core Solo, you are limited to SL (Lion needs C2D), but the procedure is identical whatever the CPU.

There used to be good lists on insanelymac's wiki, arranged by OS X version & release. Have a look there. It usually specifies everything.

No straight answer: 1st, you need a card that's the same format as yours so that the swap is easily done. Then it depends if you want a "G" card or a "N" version and for those, if you want a 150Mbps version or a 300Mbps capable one. Then, some cards will work OOB, others will need an additional kext.
