There's a known issue. Look here: https://osxlatitude.com/index.php?/topic/1533-guide-getting-1074-and-1075-to-work-on-supported-models/ I'm about to try the upgrade myself on a similar D620 (nVidia@1440x900), so will report soon on the matter.

Well... I wouldn't say it sucks, but Ok, I understand myHack is favoured over here. No offense meant... :$ I've tried to use myHack a couple of times for SL (maybe incorrectly) but had more difficulties with it than with the other installer, which I find very simple to use. Why? Because it allows me to boot straight into the installed OS without kernel flags or options before I proceed with EDP + Bootpack contents (/Extra folder) installation and it has the merit of being able to proceed without an existing Mac OS computer. Point taken about the /Extra folder, it just proved incompatible with my "non-myHack" installation method. All of this just contributes to my own knowledge of installation methods. I'm going to give Lion a try, so that'll be my opportunity to switch to myHack.

When installing on HDD with existing Win/MBR partition (that you want to retain), do not copy "Extra" folder to USB key prior to installation, but directly to HDD right after installation. Otherwise, it's impossible to install the OS on newly created & formatted Mac OS X partition as installer will want GUID partitioned disk only. Here's my method with Nawcom's boot utility, SL 10.6.3 retail DVD and EDP 1.9.2... Hardware used: D620 with C2D T7200 @2.0GHz 4Go DDR2-667 RAM, 320GO SATA HDD Broadcom 1490 Wireless nVidia Quadro NVS 110M (64Mb) WXGA+ 1440x900 LCD Audio Sigmatel 9200 1) D620 being already configured with Win7, the target was a dual-boot laptop. Existing single Win7 MBR partition was therefore reduced from within Windows to begin with. Then a new main MBR partition was created on the recovered disk space and formatted NTFS. 2) Boot using either ModCD+SL 10.6.3 DVD or ModUSB/SL10.6.3 USB key. The former does not require an existing Mac/Hack, the latter does. 3) Format spare MBR partition Mac OS X (Journaled) and install SL on it. 4) Reboot on ModCD/ModUSB and select newly installed SL partition. 5) Complete initial installation settings to get to basic running SL system. 6) Install SL 10.6.8 Combo update but do not restart 7) Copy above model-specific /Extra folder to HDD root 8) Install and run EDP 1.9.2 (model-specific kexts + Chameleon + Hibernation fix, etc.) 9) Install Ukelele + DoubleCommand for correct keyboard mappings Et voilà ...

I get the occasional system lockup, usually if I try to do too many things at the same time, not if I'm using Preview. System will become unresponsive, except the mouse pointer that turns into a coloured rotating wheel, but no action can be performed. When that happens, no solution other than power off. It this systematic on your D630 whatever the file opened in Preview or is it only with some pictures?

Are you able to connect an external USB keyboard at all? What are your D620 specifications?

If Snow Leopard is the target, why don't you try using ModCD (or ModUSB if installing from USB key) to see if you encounter the same issue? My experience is that ModCD/ModUSB gets you to initial installation completion without the need of a bootpack but a few actions are required before 1st reboot: 1) copy of DSDT file to /Extra (absolutely mandatory on Intel 1440x900 D630, otherwise black screen at reboot and external screen required) 2) install/run EDP to install model-specific kexts + latest Chameleon bootloader That normally gets to a "basic" bootable system. Updates can then be installed as required (but remember to re-run EDP after installation of 10.6.8 combo update).

Unless I'm mistaken, you can't install Windows on a GUID partition, only on an MBR partition. If you're using a GUID partition for Windows, that could explain the "Disk error" message you're getting. All my dual-boot installation were done on MBR paritions and I always installed Windows first. Once OS X is installed and Chameleon bootloader installed, I usually lose the Windows installation. To retrieve it, I boot from Windows CD and go to recovery command prompt to reactivate the partition.

On my D630 with Intel graphics @1440x900, EDP 1.9.2 works perfectly for SL 10.6.8.

Hi Tommie, EDP 1.9 is (was?) listed somewhere on this site as the latest version for D4x0. If you've lost Wireless capability but retained wired Ethernet, try & run EDP again to update your Chameleon version. It's listed in the EDP menu. That may fix things.

Congrats if you're now running on SL10.6.8. I've had a similar wireless gremlin once, where the Airport would detect Wireless networks but all connection attempts failed. Can't remember if I had to do anything to fix this. I think the problem disappeared after a while, or maybe I rebooted my Wireless router. Do you see available wireless networks at all? I don't know what it does exactly (rebuild permissions?), but did you run the EDP "fix" option (2: then 1: in the EDP menu)?

Reboot using ModCD and select your new installation to start from. Then try to re-install your bootloader. There is an option I can't recall that is listed at the bottom of ModCD boot screen for AMD multi-core CPU.

Here's what I did just a few weeks ago on a D430: Initial SL installation: 1) Installed SL 10.6.3 through ModUSB+SL10.6.3 USB key 2) Upon completion and before reboot, installed and ran EDP 1.9 3) Installed EDP kexts for D430 model -> you'll need to install kexts for your D420 4) Rebooted into SL 10.6.3 Updates: 5) downloaded SL10.6.8 Combo update (this is not the Apple Menu->Update method, search for Combo update and downloaded through your browser from the Apple web site) and installed it. If you choose the AppleMenu method, updates get installed only when you reboot the computer and then you could be screwed (I think it's Ok for D4x0, but not for D6x0; anyway better be safe than sorry). 6) re-ran EDP 1.9 to re-install model-specific kexts 7) rebooted straight into SL10.6.8 8) Installed other updates through AppleMenu->Update method.

If you follow the documented process, it's a piece of cake. Download the SL 10.6.8 update, install and make sure to install/re-install the latest EDP software with kexts for you model.

Nope, it's enabled in the BIOS and appears activated in SL. But, this being said, I've never actually used/tried BT on the D630 under SL... PS: I've PM'ed you a link to download my zipped /Extra folder.

Not on mine...

Checking speedstep frequency listing...

I used: - Simeonoff's DSDT for D630 with Intel 1440x900 as listed on my post of May 19th - EDP 1.9.2 - Voodoo trackpad/Mouse - Voodoo Battery Management But my installation was made with ModUSB + SL 10.6.3 on a USB key, not with MyHack. Maybe that's the difference

Here's what I did with EDPtool.command on my D630 was : 1) Select 'NullCPUManagement' + 'SleepEnabler' in the KEXT CONFIGURATION for 'D630, Intel X3100 graphic card' 2) Select 'Touch System...' + 'Disable Hibernation' in the FIXES menu That sorted it. I had copied the appropriate DSDT.aml file to /Extra as well. To put to sleep: Close lid or FN-ESC (not FN-F1) or Apple menu->Suspend To wake: Open lid or press On/Off button

re: bluetooth, it's supported!

To the risk of sounding daft, if your existing HDD has multiple partitions, you may need to press the right/left key to see all available disks/partitions. The "OS X Install DVD" (that's the name you ought to see) may be out of sight for that reason...

Try with ModCD (or ModUSB if you use a USB key) and make sure you copy the Intel_1440x900 DSDT file to /Extra before you reboot upon SL installation completion, otherwise you'll get a black screen at the end. I expect you'll want to upgrade to 10.6.8, in which case I recommend downloading and using the Combo update rather than the on-line update. After combo update installation, install EDP 1.9.2. Launch EDP to install model specifc kexts + Chameleon. Then, copy Intel_1440x900 DSDT file again to /Extra directory because I believe it's replaced somewhere during EDP kexts installation. You should then be able to reboot straight into SL 10.6.8. DSDT file can be obtained here: https://osxlatitude.com/index.php?/topic/88-dsdt-for-d630d830d530/page__st__20 I've detailed my successfull ModCD/ModUSB procedure here: https://osxlatitude.com/index.php?/topic/1388-d630-intel-screen-goes-black-during-boot-to-install-snow-leopard/page__gopid__9358#entry9358

Did you install the EDP sleep fix + hibernation disabling ? Sleep works on my D630 with EDP 1.9.2's help.

Which video resolution do you have? 1280x800 or 1440x900?

Check your IDA settings in BIOS (if supported - not sure on the T7250), in the Performance tab. If it's enabled, disable the feature, save and reboot. Here's what I obtain with and without IDA on my D630: It's as if FSB was reduced down from 800MHz to 732MHz when IDA is enabled, whereas with IDA disabled, the correct frequency of the CPU at every bus speed multiplier is displayed. What are your other speeds reported? If the issue is indeed IDA-related, having a FSB800 CPU, your SpeedStep emulator might display speeds ranging from 549 to 1830Mhz. IDA is not that important, since it only allows occasional brief turbo boost of a single core, whilst the other is inactive. On the T7500, it allows brief boost to x12, i.e. 2.4GHz of one core. It does not make that much of a difference to be honest.

No, Nawcom ModUSB is the tool to add the bootloader to the USB key on which a Retail SL 10.6.3 disc image is restored from another Mac. That way, I can boot and install SL from a single USB key and avoid using DVDs. SL installation is supported on an MBR partition, it just needs to be reformated. This being said, I don't know if this facility is the result of Nawcom's work or if it is simply a "standard" feature (I believe in the latter, but I could be wrong of course).
