Lookup for SpeedStep and you'll find the explanation for seeing a 2.0GHz operating frequency on your 3.0GHz capable CPU. Tjmax (max. Tjunction) is a totally different thing. It is the max. T° tolerated by your CPU before it'll auto-shutdown. For CPU T° monitoring tool/app to work properly (i.e. report/display correct readings), you need to specify the Tjmax value of your CPU in the plist file of IntelCPUMonitor kext. Tjmax differs from one CPU family/model to another, so look up for your specific CPU details on Intel's web site. For Desktop CPUs, Intel seems to provide Tcase info, which differs from Tjunction... A good article on the matter here: http://www.techreaction.net/2009/10/14/guide-to-understanding-intel-temperatures/

Hi. Re: speed, don't you know about Intel SpeedStep technology?

Here's my experience with Sleep: 1) D630, GMA graphics, BIOS A17: no BIOS password required, BIOS USB-wake can be enabled without impact 2) D630, nVidia graphics, BIOS A17: no BIOS password required, BIOS USB-wake can be enabled without impact 3) D620, nVidia graphics, BIOS A10: no password required, BIOS USB-wake must be disabled or Sleep will not be operational (immediate wake upon going to sleep).

Tss, tss, tss, who hasn't done his homework? EDP provides a fix for that. Install SoundFlowerBed, set it up and those little gremlins shall be gone.

There's one or two reported T9x00-based D630s in the Benchmarks page. 800MHz FSB Penryn C2D CPUs are supported on the D630, whatever the graphics GPU.

VLC reads and plays DVDs. Use that for your DVD-based movies.

Once you've activated speech recognition and speech commands, you should have the round speech-commands button on screen. It shows the key you need to press to use speech-commands. If you don't press that key, you're only talking to your computer like Scotty talked the Apple mouse! On my laptop , it's the ESC key (I think it's the default settings). Just tried it on my D630 GMA 10.7.4 , but it seems it only supports English (just as well I don't have a French accent!): I said "Empty the trash" whilst holding the ESC key and, woof, trash emptied! There's a folder with a list of speakable items, sorted by application.

You can install ANV-Slice kext via EDP. It'll be in the list of offered kexts if you opt for your own settings instead of pre-defined ones in menu 1. But it won't provide you with 2-finger scrolling. Instead, it's all single-finger operations: move the mouse with a "light" finger on the trackpad and roll a "heavy" finger for scrolling.

Hi, you could always check if 'Wake on LAN' is not enabled in the BIOS...

Plain French works well!

Tried the -x option as well?

To get keyboard mappings + Command/Control Ok, use the following packages: DoubleCommand: -> download and install. You'll then find it on your System Pref pane. Open it and select: Command key acts as Command Key Option key acts as Command key PC style Home and End keys -> then click on Activate and save for User & System (the latter will prompt you for your password) [*]Ukele: -> only open the package (do not install anything) and browse to the Logitech directory. Then look for the 2 keyboard definition files that suit your keyboard country and copy them to the /Library/Keyboard Layouts folder. You can then select that particular keyboard in System Pref. Pane - Language & Text -> Input methods tab. For the TrackPad, try the ANV-Slice version in the EDP kexts (using own-defined settings). To replace the Wireless card, it's just like Seb said: remove the narrow plastic cover in front of the keyboard (it lifts from the right with a small flat screwdriver or knife) and remove the 3 keyboard screws. You can then lift the keyboard by slightly sliding it forward (there are small nipples at the bottom to hold it in situ) and twisting it a little on the left and right side. You'll then see the mini PCI-E wireless card. disconnect the black and white wires and using that flat screwdriver again, unplug the card. Replace it, refit everything the way it was and you should be in business straight away with Wireless capability at the next reboot.

No Mountain Lion for Intel GMA models. Those GPU are not supported, so no acceleration and bad performance.

No need to turn too many things off in the BIOS settings. Are you running the latest BIOS by the way? Things you should enable: - Multicore support - SpeedStep - HDD AHCI mode Things you can keep enabled: - USB wake - Wireless - BlueTooth Things you should disable: - Dynamic Acceleration - LAN Wake You could also try -x boot flag to run in safe mode.

Mmm... Feb 2011: http://www.osx86.net/networking-wireless/9155-dell-d620-10-6-3-all-working-but-update-10-6-6-airport-missing.html

The supported CPU models are the same whatever the D630 model: Merom (Socket P) Core2Duo with 800MHz FSB. I think Penryn are supported too (there are reported Benchmarks here for T9300-based D630). Look at the Intel web site for those CPUs in the T7000/T9000 family (T8000 should be supported too but have a reduced cache size) and go on the scrounge for whichever you fancy. You'll see there isn't that large a choice beyond a T7500...

Hi, You seem to follow the correct procedure. EDP is menu driven, so very little text to type, just numbers or "yes/no". Do you see the password prompt when you launch EDP? Or are you saying that your keyboard is non-functional at all? In that case, try an external USB one. But I guess that you must have had the keyboard working at the early stage, at least to complete installation process and create login account... For update to 10.7.4, it's very simple: you run the Combo update and, upon completion, do not reboot but re-run EDP to re-install your kexts. Then you can reboot into 10.7.4.

I can't remember which default trackpad kext is used with the pre-defined settings. But you can always change that manually. When you opt for your own settings, info is provided about each kext and some are listed as Beta release or with known bugs. In general the VoodooPS2 works really well.

That sounds like a side effect of Dynamic Acceleration being enabled in the BIOS. Your CPU has that IDA feature as far as I know and, if it's enabled in the BIOS, disable it. IDA-enabled D630s or D830s do display lower than expected frequencies. If your "About this Mac" info displays a lower than expected frequency, check what the Simulated SpeedStep tool provides in its list. On a T9800, you would expect steps of 266MHz: 2.93Ghz, 2.66GHz, 2.39GHz, 2.13GHz, 1.86GHz, etc. to whatever lowest FID (FSB multiplier) your CPU supports.

Re: Wifi cards, I think it works straight away with DW1390 and DW1490 models. DW1395 requires specific Broadcom kexts or modified IOFamily/80211 kext (can't remember its exact name, but there's a thread about it here, somewhere).

Undervolting the CPU will neither damage the CPU, nor lower performances, on the contrary. It simply aims to reduce power consumption and heat for any given performance. It is therefore a conservative/preventive modification that should, at best, maintain CPU life and extend battery usage (it discharges less rapidly due to reduced CPU consumption). It should be without effect on the GPU since it does not alter its voltage or frequency. CPU sitting close/next to GPU, one could argue that it would reduce the surrounding heat and therefore improve GPU temp, but you'd have to see... Space remains quite tight within a laptop casing.

If you don't use the -v flag, wait a few minutes after the Chameleon startup screen and see if the laptop boots with a pale/dull flat grey Apple logo. Once booted, check the selected options in your Chameleon boot plist (found in /Extra - open it with Chameleon Wizard app). If USBBusFix is checked, uncheck it and reboot.

I envy those readings. On my D630 nVidia, CPU T° is in the mid-60s to high-70s range most of the time. It idles around 58°C. I should reactivate my Coolbook license (mislaid many moons ago) and try to undervolt the CPU like I do under Windows. This is the sort of things I run the D630 GMA on and it peaks in the low 60s (idles around 38-39°C): Under Mac OS the CPU voltage is between 1.12V (@600Mhz) and 1.36V (@2.2GHz). Quite a difference...

A quick update with my own experience at installing ML: - installation using EDP method is easy and smooth (used EDP v4-r7) - no keyboard or trackpad to start with so USB accessories are required, but they're active with EDP-provided ANV-Slice kexts - update to 10.8.1 does return error/failure messages, but update appears effective nonetheless! - reboot requests usually only close session (but it did reboot... ONCE! ) - shutdown requests often take a long long time - top menu bar would not always display until an application was launched - no SMBIOS.plist with nVidia Quadro 135m available (so nVidia GeForce 8400 displayed instead - trivial) This was the initial status with BIOS A13. Since updating to A17, I've noticed 2 improvements that I don't really explain by BIOS update: - top menu bar now always appears at end of startup - slow shutdowns appear less regular than before (1 out of 4 v. quasi-systematic before) To me, the laptop feels a bit quicker than with Lion, but maybe I'm biaised and overwhelmed by ML happiness!

+1, I never just replace the existing /Extra by that of the Bootpack, I always relaunch myHack and select "Install Extra" when creating the USB pen (I think the option of the Generic or Own /Extra is only offered at OS install). One comment about your 4th point. When you say you browse to your 10.7.2 image, what do actually point to? The "Install Mac OS X Lion.app" of the "InstallESD.dmg" image which is only found by right clicking onto the .app image to browse its contents and going to Shared Support folder? It is the ESD image that you should point to. As such, you need to copy it onto your desktop or someplace else because it's not directly accessible from myHack as .app contents.
