I've got that D830 back right now. It has: Intel T7250 2.0GHz Core2Duo CPU 2Go DDR2-667 RAM 120Go SATA HDD DVD +/-RW in Modular Bay nVidia Quadro NVS 135M (128Mo) video controller (Video BIOS v060.086.068.000.017.000) WXGA (1280x800) LCD Sigmatel 9205 Audio Conexant HDA D330 MC modem (not that this matters...) Dell DW1490 Wireless card Dell 360 Bluetooth adapter BIOS A16 The BIOS settings are configured as per my related post in D8xx section. HDD is GUID dual-partitioned: 1st partition is ML (Mac OS X extended (journaled) formatted), 2nd one is Win7 (NTFS formatted). I can boot my ML USB installer (=myHack v3.1.2 10.8 installer with legit' retail Mac OS X 10.8 + myHack Create Extra with OSXL D830 nVidia bootpack) without problem and proceed with installation. The only boot option I use is 'USBBusFix=No', although it's not mandatory. Are you guys 100% certain of your ML copy or are these just downloads??? That D830 was finalised with EDP v4 r29. Chameleon bootloader (re-installed from EDP) was updated to v2.2 r2110 and Chameleon boot plist settings are exactly as shown above. SMBios was set to MacBook Pro 3,1. It's not running on the best FSB800 C2D CPU, but it runs ML 10.8.2 just perfectly. Boots in 60s, shuts down in 20s flawlessly.

Not owning one, I don't know how the D520 is built but I can tell you that on the D620/D630 and D820/D830, you most usually have to completely open up the laptop and remove the casing top part to access to the fan & heatsink and properly remove the clogged dust. I did this on my D620 when it started to heat up a few months ago. I had previously put a hoover hose to the undertray and lifted the keyboard to blow compressed air but that did not really help. Once I fully opened it up, I found a 3-4mm layer of dust tightly built in the small gap between the fan casing and the heasink radiator grill. There was a narrow piece of sticky tape on top of that. Nothing made that clogged dust go away but my own fingers...

There are no files to replace at all to begin installation, not even the IO80211Family kext that you mentionned earlier (that can be done post-installation if you have a DW1395 Wifi card). I've installed ML on a D830 nVidia 135m just a couple of weeks ago and had no issue whatsoever. I was also using the very 1st release of ML 10.8 (a legit' copy, source unknown = you're on your own!). Once EDP is installed, you can update to 10.8.2. Just make sure to create your myHack 10.8 USB installer properly, mounting the 'install ESD' image located inside the ML package and add the D830 nVidia bootpack afterwards. That's it, no need for a full fix at that stage. If you get that done, ML installation will go through without hiccups. Boot your installer with option 'USBBusFix=No' to avoid lengthy/slow boot off installer media.

1) Install SL with myHack USB installer (retail SL 10.6.3 for instance) 2) download EDP, install it and run kexts installation *** 2.5) you may want to reboot at that stage to verify your SL installation *** 3) install 10.6.8 combo update but do not reboot on completion 4) re-run EDP kexts installation 5) reboot in SL 10.6.8

If you haven't got a legit' copy of Mountain Lion, who knows what you got? Read this, it says it all! http://forum.osxlati..._300#entry14063 Buy it, it's only 18€... Nothing wrong with your 2.2GHz T7500. That'll run ML all right. Keyboard problem at Lion installation is known issue, boot with USBBusFix=No to avoid that.

I couldn't really tell the difference between Lion and ML on my D630 nVidia, but I'd say it did not appear slower under ML. Now I have a SSD drive in that laptop and it runs much faster.

Boot flags begin with a '-'. Eg: -x -v -f. Boot options do not. Eg: USBBusFix=[Yes/No] cpus=1 arch=[i386/x86_64] For instance, type (literally): -x -f -v USBBusFix=No npci=0x2000 You can type '?' after pressing [ENTER] at bootloader delay bar to get a list of flags and options (it's not necessarily the complete list). Follow the casing.

That explains, I thought you were running ML...

Yep, you're spot on with your 2nd edit: boot off Nawcom's ModCD and install SL off retail DVD = temp platform to create myHack installer. Ok, it's not the shortest way, but it's one that does not require access to an existing Mac or Hack...

Is it really reporting a Quadro NVS 110M? Or is it a NVS 135M or 140M? It's just that the 110M did not appear to be supported under ML and the D620, fitted with that specific nVidia GPU, was therefore limited to running Lion at best. So, it'd be kind of interesting it your Acer was indeed reporting running the NVS 110M...

Nope, never tried/used. I was able/lucky to start off with NawCom BootCD and SL retail DVD and never been without a Hackintosh since; so never had any problem to create a myHack USB installer...

Basically, you're asking if can OS X be installed straight away on a PC (it's a recurring question...). distros will somehow support this, but distros are bad: it's piracy, it's not often clean, you'll have no support for this here. In other words, you're on your own with distros... Nawcom BootCD basically offers a bootable CD to install Snow Leopard off a retail DVD or USB key, running legacy kernel. I started with that during my very early days of Hackintoshing when SL was the current version of OS X... I can be used as a temp platform from which to create a myHack USB installer. other ways that you'll find elsewhere and for which Google is your friend. For OSXL EDP-based procedure, you need a legitimate copy of OS X and access to an existing Mac or Hackintosh to start with...

How did you create your myHack USB installer? Did you mount the 'install ESD' image/package from within the ML image?

GM965 is a chipset. It includes Graphics Media Accelerator X3100. What you call GM965 graphics drivers are X3100 drivers. Information about your individual H/W is available in the BIOS system info pages and you'd find that EDP kext installation specifies the audio chip model (and kext) for the D630. If your system KPs, it's not because of EDP-provided kexts, as long as you selected the right model...

The D630 is a better machine with improved specifications (FSB speed and graphics for example). Read up the different web site pages for an overview of each model capabilities and the EDP-based installation procedure. In a nutshell: . D620 (GMA 950 & nVidia) -> Snow Leopard/Lion . D630 (GMA X3100) -> Snow Leopard/Lion . D630 (nVidia) -> Snow Leopard/Lion/Mountain Lion

By all means, do try, but we've had quite a lot of people reporting problems with VM.

Our method is to create a USB installer key (with myHack) and add the model-specific bootpack. You need to start by that but it requires access to an existing Mac or Hackintosh. Basically, follow the EDP procedure detailed in the top menu of the form/web site. For Lion, make sure you install a retail version lower than 10.7.4 (eg: 10.7 or 10.7.2) to avoid installation problems.

Hi, how did you install Lion on that D620? Try and boot with -x -v -f parameters to see if you can go through.

The M4300 is pretty much a D830 with a professional graphics card (Quadro FX 360m vs. Quadro NVS 135m/140m) When you start the USB key installer and you see the scrolling blue bar, press [ENTER] and type: USBBusFix=No npci=0x2000 -v See if that helps. I'd also recommend that you look at the BIOS settings for the D830 nVidia and configure your BIOS in an identical manner.

EDP does not know what CPU any given laptop may have, so it does not "update" the IntelCPUMonitor.kext in /Extra/Extensions. On the contrary, it replaces the kext with a sort of default version where TjMax will have a preset value (eg: 0). You need to open up the kext and edit the 'info.plist' file with a text editor (or a plist editor) to set the TjMax parameter to the value that suits your CPU (get that info from Intel web site by typing "Intel Txxx" on google, where Txxx is your exact CPU model). Save the file, re-run myFix (full) and reboot. Your CPU temp will then be properly reported. On your D630, I'd expect your 2.0GHz CPU to be a T7250 or T7300 and TjMax for those processors is 100°C: http://ark.intel.com...GHz-800-MHz-FSB http://ark.intel.com...GHz-800-MHz-FSB There is a thermal pad on top of the GMA chip or nVidia GPU, but there is always thermal paste right on top of the CPU. That will harden and more or less disappear with time.

Try and boot with the following options: USBBusFix=No npci=0x2000 If you manage to boot, give us the contents of your Chameleon boot plist (it's best to use Chameleon Wizard for that). It'll look like this:

90 to 99°C is way out of what you'd expect on the GMA model and, to me, it must be due to a physical issue. As Bronxteck suggests, do check your CPU heatsink + fan as that's most likely where your problem is. You should also verify that your temp readings are correct. What CPU do you have and did you update the Tjmax settings inside the plist file of your CPUmonitor kext in /Extra?

Which release & version are you trying to install? If Lion 10.7.4, try with a lower version like 10.7.2.

You can't from a Win base, you need a Mac or a Hack. But there are ways to circumvent that issue with bootable CD installer like ModCD that will allow you to install legacy-kernel SL. That can then be used as a temp platform from which myHack can be run...

Hi, please provide the specifications of your D630 and make sure you don't have any incompatible HW like an Intel Wifi card. Once it's established you're starting from a sound base, I'd suggest you boot your installer with option: USBBusFix=No
