Do anyone know how to install Mountain Lion on Dell XPS 15 L502X?
I tried typing GraphicsEnabler=N cpus=1 busratio=20 with and without -f or -x or
npci=0x2000 or PCIRootUID=1 but not thing is working. I can't even boot into iATKOS ML2 usb installer and i know the iATKOS_ML2.dmg file is working because i installed it on my other laptop.
The USB is already setup with ML2 Bootloader_installer.pkg and restore with iATKOS_ML2.dmg
Every time i boot the USB, i have a no smoking sign but without the cigarette so i boot in to verbose boot (-v) i got an error. It said "Still waiting for root device." -> -> ->
Dose it matter if i update the bio to the latest version and what should i do????
