I posted about this a few months back, but after a few days I found I didn't have the time to continue messing with Mountain Lion on my Inspiron 1520.

I followed this guide: http://legacy.tonyma...p?f=170&t=26283
Only problem is, Chameleon won't continue after I select which partition I want to boot from.

I figured that the process for Mountain Lion would be about the same as it is for Lion (I don't have a copy of Lion).

I tried selecting Lion_USB from the menu, but then it just goes to a gray screen and reboots. I tried with the suggested flags ("arch=i386 -x -v"), and that spat out very little text and jumped back to the menu. I tried with just "-x -v", and then it loaded all the appropriate kexts, got a bit past "Restart fix applied" (that's as far as I was able to read) and rebooted.

I feel bad for letting my previous post die, especially since I was being helped (thanks eep357!), but I guess I just got swamped with work (yay college).

I'm currently trying this guide: http://www.insanelym...-mountain-lion/
I have my doubts as to whether it will work though, considering it's made for Gigabyte motherboards, and this Dell laptop is hardly that.

EDIT: SOLVED! DSDT patched by LatinMcG: http://www.insanelym...0/#entry1886726
Booted properly with a new copy of Lion (not ML) and the "-v" flag.

Specs:
Dell Inspiron 1520
Intel Core 2 Duo T7500 2.4 GHz
nVidia NB8P-GS (I think that's a GeForce 8600M)
2 GB RAM

Thanks in advance for any help!

follow the dsdt guide for m1330 and also there is a guide for many dell laptops.. u should be ok following that

main thing for Lion on this 1520 is.. the DSDT Device (PCI0) is missing _UID under _ADR
without it lion wont work.

also almost all regulars here dont use tonyschmucX69 stuff

I found the issue with Chameleon not starting. It was because the method in the guide was for Lion only. I got a copy of Lion from my roommate (who owns a Mac), and I was able to complete the first 17 steps. Now I'm stuck at a kernel panic saying "No HPETs available...CPU(s) configured incorrectly". I've attached a photo.

Here's what I've tried:
Used the DSDT with the guide, flags:

• acpi=i386 -x -v
  
• -x -v ForceHPET=Yes
  
• acpi=i386 GraphicsEnabler=Yes ForceHPET=Yes -x -v

I also used the DSDT here: http://www.osx86.net...on_1520_a9.html with the same flags.

I tried to use the guide you posted to patch the DSDT, but it would have taken me hours to get all the code corrected. Also, I wasn't really sure if all of it would apply to my machine.

try -v -f

also check your dsdt to the one u dloaded.. memory size prob dont match

[Turaiel]

I tried those flags with no DSDT, and with the two DSDTs, and I just got the same kernel panic.

[LatinMcG]

dump your dsdt .. do from linux or windows.
then we compare the memory line.

[Turaiel]

Alright, I started a live CD and used acpidump to retrieve it. It's attached.

i see problem. the HPET is not fixed in that dsdt
ill fix it

here u go http://www.mediafire...s1u6rb4ys56m669
i cant test as i sold my 1520 nvidia 8600 .. but i do have 1520 intel video card that is harder to get to work due to intel video changes in 10.7

[Turaiel]

Thanks! I added that DSDT, but now I'm having an issue with "Still waiting on root device"
Ideas?

EDIT: I applied modifications listed here: http://www.insanelym...y/#entry1862155 and booted with "-x -v". I was able to get into the installer, but then I got an error, and the installer was unable to continue. The install error log is attached.

your bios got reset likely from no dsdt and it sets to ide mode not ahci. check bios

[Turaiel]

The BIOS is still how it was before, set to AHCI.

Also, I tried again without the modifications from the link I mentioned and got the same result.

[Turaiel]

Fixed! Turns out, the copy of Lion was corrupted. I got a clean copy from my roommate and it's installing as we speak!

Thanks for the help and the DSDT!
