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)
Intel SpeedStep: Enabled
Virtualization: Enabled
Integrated NIC: Enabled
USB Emulation: Enabled
USB Powershare: Enabled
USB Wake Support: Enabled
SATA Operation: AHCI
USB Debug: Enabled
External USB Ports: Enabled
eSATA Ports: Enabled

Delete the nvidia kexts and intel kexts from the S/L/E directory. OSX starts to load the graphics drivers after loading the PS2controller

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
