Alienware M17x R4 - Boot fails @ ApplePS2Controller timeout

Hey all,


Proud owner of an M17x R4 (Intel i73630, Nvidia GTX 675); however, I can't seem to get this thing to boot with Mountain Lion.


The problem:


Using iatkos ML2 on a bootable USB everything works great using -v and -x UNTIL I get to this line while booting

  • ApplePS2Controller: Timed out on keyboard input stream
  • Waiting for root device

I plug in a wireless USB Keyboard + mouse, reboot using the -v and -x flags and I get the following lines

  • ApplePS2Controller: Timed out on keyboard input stream
  • com.apple.AppleFSCompressionTypeDataless load sucessful
  • com.apple.AppleFSCompressionTypeZlib load successful
  • Waiting for root device

After scouring forum after forum, it seems I am the only one having this isue? iATKOS ML2 is the third OSx86 software I use that results in that line (Previously tried TonymacOSx86 and some other thing)


BIOS Config (Note, it is not unlocked)

Virtualization: Enabled

Integrated NIC: Enabled

I had the same issue....Up until last night, as I have fixed mine.


Go into your Bios and disable eSata under misc options, I then had my USB plugged into the eSata port and it boots no problem, hope this helps
