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).

Hi, I'm still up for that guide if it's readily available.

HDD reformat is the best option to ensure a fresh clean install. You're garanteed to be rid of any rogue items that way. One small advise: Win7 installation program always creates a 100Mo partition of you start from a partition-free drive. It's not really needed and you can easily bypass it: simply re-partition your drive prior to Win7 fresh install and just select the existing partition at Win7 install.

Good stuff! Do give us the way you manage to get everything working, it can always be useful to others.

There are 2 ways to indeed follow the AMD guide with Nawcom bootloader + USB key (8Gb minimum, 16Go+ is best) where an SL image has been restored (needs another Mac to do this): 1) Boot from CD/DVD with ModCD + USB key plugged in. Select the USB key when the various discs appear. 2) From another Mac, apply ModUSB package to the USB key containing SL restored image. You can then boot straight off the key and not use the ModCD, provided your PC supports booting from USB (most do for several years now). This is a good "general" installation method and I've tested it on an AMD Sempron-based Acer Aspire 7000. Installation process + end result were dissapointing (laptop running like a dead dog, even during installation, possibly due to lack of GraphicsEnabler), but it went to completion. If you do not have a Mac, you may try to copy the "boot" file + "/Extra" folder of Nawcom to the root of the USB key, then install a Chamelon boot loader on top of things to effectively boot from the key. Never looked at how to do that very last part I must say, I've always used my Leopard-based Inspiron 6000 when I needed a Mac at various stages.

I did not need to apply the D430 BIOS password procedure to get sleep to work on my D630. I "only" had to follow the model-specific kexts installation, followed by Hibernation fix. That was enough. EDIT: I can close the lid or select Apple-> Suspend or press FN+ESC to put D630 to sleep. It'll wake when I open the lid or press the power button. Without this step-by-step procedure, I could put the D630 to sleep Ok, but it would immediately shutdown and restart with complete BIOS reset to default at any wake request.
