Hi docimo... To improve system stability, after installing new kexts (like after running EDP), the old kext cache should be rebuild so that the new kexts are loaded on next reboot. If we have not rebuild the old kext cache, we can force OS X to ignore the old kext cache and reload all kexts (including the new kexts) on boot up by using the -f flag from chameleon (ie. mach_kernel -v -f). The -v flag is to hide the gui and show the kernel boot up messages. Sometime, new kexts are not loaded even after using the -f flag until we rebuild the kext cache. Cheers!

Hi... From OS X, you need to open the "Disk Utility" application in the "Utilities" folder. Select your OS X partition on the left tab and then click the "Repair Permission" button. Cheers!

Hi... Have you tried to repair permission with disk utility? Cheers!

Hi... Its great that you got your system running. By the way, usb keyboard is required after first install. After that, the built in keyboard should work again. Further, the AppleHDADisabler.kext in E/E is used to disable the AppleHDA.kext in the S/L/E so that VoodooHDA.kext can be loaded. Otherwise, it will cause a kernel panic. Cheers!

Dear jada, I think it may be related to to the dsdt or kexts in the extra specifically for the D620 model. Have you tried to reinstall EDP? Cheers!

If you are running os x, you can run system information and go to Extensions to see which kexts are loaded.

Hi cypress, Here you go : http://osx86.tistory.com/243 Enjoy!

Hi cypress, I did came across a website that list down all the kexts and explains what each kext are for. Let me see if I can find it again and will let you know. Hi Rhyker, Food for thought.. Isn't that what kext cache is? Cheers!

Hi jada, Have you check the bios to make sure wifi is on? I made a similar mistake where I open up everything only to realize that my bios setting for wifi is off Cheers!

Hi alticavis, I too have just upgraded my D520 from core duo 1.66 GHz to core 2 duo 1.66 GHz processor. A big jump I guest from 32-bit to 64-bit. The most important thing is that the FSB for the new processor must the same as the old one. Apparently FSB is the only requirement. Secondly, make sure you have the socket that is detachable (Socket M or 479 if i remember correctly)to make sure that the old processor is not welded to the board. Best to open up and see for your self I guest I'll advice that you update your bios to the latest (in case the old bios does not recognize the latest processor). So far, for me, upgrading the processor and updating the bios has no effect on my lion installation. Well, that's my experience. You should get more second opinions to make sure (especially on the heat sink if your new speed in higher that the usual maximum processor speed for the model, as in my case core 2 duo 1.66 GHz is the highest I've come across so far for D520). Cheers!

Hi jada.. You should go for the broadcom wifi and nvidia graphics. However, make sure the broadcom wifi is supported. Check the wiki section on rebranding broadcom wifi for list of supported model. Furthermore, as the upcoming mountain lion will most likely drop support for intel gma 950 and x3100, you should steer away from those cards and go for nvidia cards. Cheers!

Hi Darvinko / dwdocimo, Darviko, Have you tried to boot into your new lion installation in safe mode and running EDP tool from terminal? dwdocimo, Have you tried to boot with mach_kernel -v -f after you installed EDP? By the way, whats you laptop's spec? Cheers!

How jerky is your D630? I don't really find my D630 too jerky, unsmooth or unresponsive for it to be a problem.

It seems you have the same spec as mine. Yes. I have also found my D520 with GMA950 GPU more responsive and smoother as compared to the X3100 GPU. What bios version are you on for your D630 at the moment?

Which graphics card and screen resolution you have for your D630?

Hi Mad, Have you installed EDP, repair permission and rebuild your kext cache? Cheers!

Hi... Software updates should be ok. The only case when we need to be careful is os x updates. Need to check if EDP is available first or update at our own risk (or for some brave souls, try it out and let others know how it went). Cheers!

Hi... Chameleon is a two stage boot loader (if i'm not mistaken). boot0 is installed inside the master boot record and boot1 is installed inside the boot sector of the os x partition. Basically, when you start up the laptop, the bios will boot the boot0 (aka mbr), boot0 will boot the boot1 (aka boot sector) and finally boot1 will boot the boot file (i'm guessing this file boots the mach_kernel and do all the EFI injections) in the root directory. These files are automatically installed by the chameleon installer. You only need to install chameleon once. If you install the new osx partition after the old osx partition, you don't need to install chameleon on the new os partition. Chameleon can access boot1 and boot from the old osx partition and give you the option to boot the new osx partition. However, if you install the new os before the old os, from my experience, chameleon will always look for the first os x partition it can find. And if there is no Extra, it will still start the boot loader but no pretty gui and dsdt & com.chameleon.Boot.plist is not loaded. You'll need to copy or install just /Extra to the new osx partition (copy or using EDP). My guest is because you install a second chameleon on the new osx partition, the boot0 is confused which boot1 to boot or maybe boot1 is confused which boot file to boot and hence it will always boot the first one it finds. I guest when you boot from usb, it will boot boot0, boot1 and boot from the usb and chameleon will load mach_kernel in any os x partition you select. Phewss.. Did I got my cause and effect analysis right there... Cheers!

Hi... To try to boot into lion on hard disk, you can boot into installer usb and remove / rename the Extra on hard disk from Terminal. Its seems your dsdt, org.chameleon.Boot.plist or kexts in E/E may be causing kernel panics. May I suggest you solve one problem at a time that is causing the KP rather then going it randomly or by trial & error... hehe.. Cheers!

Hi elim.. You can run edptool.command to rebuilt kext caches in S/L/E and /E/E. I prefer to use kext utility. Cheers!

Hi blueadrian... Can you give more details on the message after kernel panic? I think it may have to do with the AppleIntelCPUPowerManagement.kext being loaded but need to see the full KP message. Did you try to use the -f boot option? It will bypass the kext caches and load only relevant kexts. Cheers!

Hi bronxtech... Thanks on pointing out that the enabled dynamic acceleration is causing the cpu speed to be shown lower than it is. I have always been wondering how to solve the 'About This Mac' showing my 2GHz cpu as 1.88 GHz instead of now 1.99 GHz. Yeah... Its superficial... no marked difference on my geekbench... huhu... was hoping it would touch 3000++ maybe. Hehe. Cheers!

Hi... Cloning an os x partition is straight forward with the tools mentioned above as os x can easily boot from any new partition created. Cloning a windows partition is tricky as it may not boot from the new partition created. So far I've been successful using winclone only. However, you need to a create an external or second hard disk with os x system as the winclone will unmount the whole hard disk and not just the windows partition. Cheers!

Hi.. The BCM5722D.kext in Extra should have been loaded. What network card is installed on your system? Cheers!

Hi... I was able to boot os x snow leopard on my office dell optiplex 755 with core 2 duo processor. Managed to get the network card working with a kext I found so with internet access anything is possible. But without any 3100 graphics card (desktop version) kext available I kind of given up. Cheers!
