Mac OS X 10.8.1:
Manually install the update, before resetting do the following:
  • Rollback AppleSmartBattery.kext if VoodooBattery isn't installed.
  • Rollback AHCIFamily.kext to be able to boot with the kext cache
  • Optional: If Wi-Fi doesn't work restore IO80211Familly.kext

Typo?
Guess you mean IO80211Familly.kext ? :P

I'm giving the wireless-fix a try, since i've got connectivity problems with ML and Wireless:
Got two Wifis up and running - one on 2.4GHz band, the other on 5GHz.
Since ML connecting to the 5GHz Wifi works, but ML behavior is like there is no DNS present. Sometimes even no connection over IP.
2.4GHz no prob at all.

5GHz Wifi working on Windows & 10.7 flawless


EDIT:
Update installed, rolled back IOAHCIFamily.kext, reboot, done :)
2.4 GHz Wifi working. Testing 5GHz when im back home.

Thanks @DoiX. I did this about a week ago, through the software update. I didn't have to roll back anything, and the XPS boots up fine. The update to 10.8.1 was only about 8Mb though.....

@DoiX,

With XPS 15, when i plug in the ZTE AC8700 USB2 dongle into the USB 3 port, it is detected fine. But as soon as i start the associated application the app freezes and fan starts throttling high (and it doesn't work).
Though i know that the driver is somewhat quirky but it did work in Snow Leo. (Though, i am using an updated 64bit driver on ML)

What is see in console is that, PXHCD is converting the USB3 input from the port to USB2 (as per the USB2 specs) but it hangs there. (I guess the USB3 driver needs to mature more).
In windows the EVDO works well on USB3 port.

FYI, EVDO works fine with USB2 port.

Please share your views/insight on this topic.

Thanks

USB3 fails when it comes to devices that require the interaction of other drivers. Basic storage and charging will work. The charging bit is somewhat random with iDevices, sometime it throttles the fan up (means the kernel is in overdrive) sometimes it just charges them silently w/o problems.

My last DSDT version (if you're using it) has a code for some slow/basic native USB3 support... you can remove the PXHCD kext and boot into OS X with the modem connected. It will be slow to get it detected but maybe it will work just fine after that.

The PXHCD is patched to remove a check if memory serves, it's possible there may be some other check when it comes to interacting with other drivers.

No, its just a stock 500Gb HDD. Is that important?

I was curious if the "waiting for root device" error on ML with UseKernelCache=Yes persists with SSD as well. Because, according to BCC9, this happens when the kexts are loaded too fast and the chipset one isn't initialized on time.

OS X Leopard isn't even compatible with sandy bridge processors, and i doubt someone went the trouble to create a kernel for that... unless some legacy one provides some basic functionality, either way... i don't even support Snow Leopard on this laptop because it's just too much of a hassle and less of a "vanilla" experience.

So, why did you install that in the first place?

I did not install this. I was able to boot it. I cannot boot any Lion (iATKOS L1 or L2) installers. I get stuck at the /|\ roatating screen.

Oooh, well explain it better the next time. Did you boot with -v -x ? Is the \ spinner screen the one after it says its loaded darwin/smbios/DSDT ?

Yes but I am not able to get to the point where I can use any options (-v -f -l...etc)

That's a corrupted bootloader or an extremely old one. Unless there is something physically wrong with your system that manifests itself when the second RAM slot is used. Keep only one ram module in the slot you just updated and remove the other one, see if it works. If not, move it in the old slot... also switch around the memories.
