Hi

 

I was reading about mlpostfactor: http://forums.macrumors.com/showthread.php?t=1325709

 

Would this really enable Intel950 support on a D430?  I think it somehow forces a 32bit mode and so uses 32bit drivers?  Beyond me ... any comments?

 

 

 

Thanks - that makes sense. Any pointers for how this can be done with a non-booting system (USB key, alternative OS)? I did a quick google, but was only able to find directions once in OSX.

 

 

 

OK, thought about this a bit more - obvious: run Chameleon from USB key I made for the install, F8, select the OSX partition on my HDD. Once in OSX, install chameleon onto the HDD partition again.

Dear balchy,

 

You can set the uuid of new partition to boot by reinstalling chameleon.

 

Cheers!

incidentally, I have managed to suffer from this problem without any BIOS changes ... but I can't reproduce it easily - I have just updated my mainboard to a D430 and am waiting on correct memory so I can install OSX Lion. I have reverted to the old process, so wrote my SL DVD to a USB key, installed, then installed Chameleon + EDP 1.9.2

set bios to defaults and save then reboot and readd your tweaks

 

Hi - thanks, I should have tried that already - however, it did not work.

 

Obviously, I can re-install.

 

I was just hoping there was some kind of way I could change the "ID" of the disk the bootloader is looking for. I see this is possible in the help that comes up in the bootloader, but I don't know how to determine if that's the fault or how to change.

Is that a HDD password in the BIOS? Might be a stupid question - but removing the HDD password in the BIOS does not rectify the situation?

 

Ha! Good questions.

Yes - HDD password in the BIOS. Tried removing it, and still no boot. It's my guess that the password caused it; I noticed I got a "please wait" when I set the password for the first time, making me suspect something is written to disk.

From my reading around (it's confusing) I think the key thing is Core Duo or Core 2 Duo.

 

I have a D420 using a 1.2GHz Core Duo.

 

Processor ID is 06EC

 

Intel says this is 32bit instruction set :

http://ark.intel.com/products/27240/Intel-Core-Duo-Processor-U2500-%282M-Cache-1_20-GHz-533-MHz-FSB%29

 

So, this is definitely "dual core" but not 64bit therefore NO Lion install possible.

 

I think an update/guidance on the EDP page to check your processor ID might help some confusion. The requirement is both dual core + 64bit instruction set (please, correct me if I am wrong)

 

Finally, off topic, a bit.

Incidentally, for Snow Leopard, I have used the "single core" EDP pack successfully ... no idea if the "dual core" EDP pack would work ... might try it one day.

 

Also, I have bought a d430 "base" on ebay that I hope I can transplant into my D420 and get me the Lion!

Hi all

 

Had decided to re-install SL on my D420 (duo) - first time using the myHack app - excellent!

 

I removed the bios (system) password during install, just for convenience.

Once installed and EDP set up, and after a number of successful reboots, I move to enabling sleep. However, I incorrectly set an HDD password, not the system one.

Now my system does not boot up.

 

If I run boot using -v I get

rooting via boot-uuid from chosen: [long sequence of characters]

From path: "uuid", Waiting on [blah]

"still waiting for root device"

 

I assume because setting an HDD password somehow changes the way the HDD appears to the boot loader.

Obviously I can reinstall, but I wondered if there is a way to configure it to use the "new" HDD?

 

Thanks for any help.

 

I can take a photo of the screen if the text is relevant.

I was thinking if I can determine the correct device ID I can tell this to the bootloader.. ?

Thanks very much - BIOS to defaults fixed it! I already had the password set.

Hi

 

I have a D420 working well now on SL 10.6 but cannot get sleep to work.

 

Spec - D420 dualcore with 2gb memory, broadcom wireless (replaced) Snow Leopard 10.6

 

Steps taken so far:

 

Followed WIKI guidance on fixing sleep

Using: EDP 1.9.1, and then EDP 1.9.2 from a previous post from Leon (fixed sound for me)

both with and without "nullcpupowermanagement" (though I think I shouldn't expect sleep to work when this is installed) without sleepenabler.kext

 

Not tried:

sleepenabler.kext (I am not sure how to identify the right one to use)

updating to a more recent SL version (reading about networking issues, so want to avoid)

 

Laptop never successfully goes to sleep.

 

With nullcpupowermanagement, press power button, select sleep: screen goes off, but fan etc does not power down, power light does not pulse and I am unable to wake - have to force a reboot with long press of power button.

 

Without nullcpupowermanagement, press power button, select sleep: screen goes off, powers down, power light pulses. If I press the power button again, I get a full reboot. Keyboard, trackpad buttons do not wake.

 

Not sure what else to check or reconfigure next...

 

 

Thanks in advance for any advice

Hi - just registered to say thanks to all the experts here on this forum. I have a fully functioning D420 using OSX thanks to the resources here.

 

I did have a problem with audio - did not work after EDP was run.

I fixed it using EDP 1.9.2 and the advice from Leon provided - wanted to share, as I found no other mention of the problem/solution for D420 (though I know it quite similar to a D430, for which this advice was given)

Try this pre-beta of 1.9.2 : http://cl.ly/420U3k0C3y1k0k102F2e

 

1. remove your /Extra

2. Unzip the zip to /Extra

3. Run edptool.command

4. Reboot

 

 

Hope it's OK to link to the download.
