Hello all,

I have a Dell E6400 that I am trying to install Mountain Lion DP4 on. I currently have Lion on it with most things working. I cannot get the Mountain Lion USB Installation Drive to boot though!

Everytime I try to boot the installation, I get "Still waiting for root device" (after a few lines beginning with USBF; nothing to do with EHCI (at least I don't think) which is what most other people are experiencing )

I have tried every boot flag I know of:

-x
graphicsenabler=no (and yes)
USBBusFix=Yes
npci=0x3000 (and 0x2000)
cpus=1 (and 2)
pcirootuid=0 (and 1)

I have also replaced most of the kexts from Lion that were problematic in Mountain Lion.

Lastly, I boot with "arch=i386 graphicsenabler=yes" to get into my current Lion build, which leads me to believe that I needed to do this with Mountain Lion too, however whenever I boot with arch=i386, the Mountian Lion install just takes me back to chameleon. From what I've read so far, Apple removed the 32-bit kernel from dp2 and up.

So I guess my question would be do I need the kernel from dp1 or do I need to do something differently to get past the "Still waiting for root device" error?

Any help is greatly appreciated.

Thank you

Hey artur-pt, thanks for the Reply. I updated my signature with the relevant system specs.

I guess my next plan of attack is to get DP4 working with the DP1 kernel?...I am slightly new to this and I'm not even sure if that's possible (copying over the mach_kernel from DP1 to the DP4 installation usb).

Once again, thanks.

hello

i think the problem is not in u cpu , is a c2d, so can run in 64 bit

maybe u graphics, or use some kext u are using in lion.

if runs lion good without issues, must run ML.

good hack

Thats exactly what I thought, but it doesnt apply to my system. Lion runs perfect, ML doesnt even boot :S

When error messages appear, unplug your usb drive, then plug in it again.

hi

check the install

if any problems with usb, creat a small partition in the hd for the install (8gb)

The only real error message is "Still waiting for root device"

I did try unplugging and replugging the USB Drive in again and also with different ports (I have 4 in all, and have tried all of them to no avail)

I had the same "Still waiting for root device" error (and USBF messages as well). The boot sequence paused there, I just unplugged, replugged the usb drive, and it continued to boot.

Since you are unable to boot Lion without arch=i386, start there. Once you figure out what you need to do differently to boot Lion in 64 bit, chances are it will also be what is preventing you from booting Mountain Lion.

First of all, sorry it took so long to respond. I've been quite busy lately.

Second, I tried booting lion in 64 bit and it works (for the most part)! The only things that don't work are the keyboard, mouse, and the screen resolution is off, but I can fix all of those if I can just get Mountain Lion to install/work!

and when using small partition on internal HD instead of USB?

Again, sorry for taking a while to answer. Been very busy lately.

Anyway, when trying to boot the installer from a small partition on the internal HD instead of the USB, I get a kernel panic at the following line:

"Unable to find driver for this platform: \"ACPI\"

Any help is greatly appreciated. I can't wait for this to get done!

Download and install both these to your installer using Kext Wizard and repair permissions and rebuild the cache appleacpi and iopci.zip if problem continues I have another idea.

No dice. I used the two kexts, booted in verbose mode, and still nothing.

Btw, thank you very much for your help

try bypassing the cache, use boot flags:-f -x -v
probably need to also include: PciRoot=1 USBBusFix=Yes GraphicsEnabler=Yes npci=0x3000
the key there is -f since you tried all the others

Well, I've been waiting for Mountain Lion (the final release) to retry my installation and would like to update everyone on the status so far.

I have been stuck at the same error(s) and none of the above flags that eep357 mentioned seem to do the trick.

Here's hoping that someone has better luck than me...

Thank you for any and all suggestions. They are greatly appreciated

For Dell E6400/6500, remove all AppleIntelHD* files in S/L/E on your USB install drive before install.

I've a working OS X Lion on my Dell Latitude E6400,P8600 2.4 GHz,4G RAM,64G M4 SSD.
Hope someone can help me work out how to solve this,I really appreciate it.

I have compiled a guide to installing Mountain Lion on the E6400/E6500 at Osxlatitude.com. Thread title is Mountain Lion anyone? Other than some sleep issues, everything appears working.
