  1. Hello! I actually don't know where to post this... I run an intel-powered multiboot system (one HDD is Mavericks 10.9.2, the other one is Windows 7). HDD with OSX was the primary one to boot, all was fine for half a year, but today I was rebooting from Win to OSX and somewhy it was Win booting again (despite OSX HDD priority). I rebooted again and got the "The data in EC or EC flash might be corrupted" error. Extracted the battery of the motherboard for 5 minutes, the error's gone, but OSX just won't start - stuck on flashing "_". If I disconnect the Win HDD, the system gives me "Reboot and Select proper Boot device or Instert Boot Media..." etc. Windows boots just fine for some reason. What could be the problem and how to fix it? Main components of the system: intel i5-2500 3.30ghz Asus P8Z68-V LX AMD Radeon HD 6800 Don't know how to delete the topic and if I need to at all. Maybe it would be useful to someone, maybe not. SOLVED! - created a bootable usb-stick using Mavericks ##### (yeah yeah those guys) from my another mac - booted up from the stick choosing to boot from my HDD which contained installed OS X - found a problem with "Missing Bluetooth Controller Transport!" - booted up in safe mode with -x, added dart=0 to the chameleon's kext in /Extra This fixed the problem. I guess, something went wrong after resetting the BIOS (VT-X appears disabled there). Solution was inspired by themacmeister from reddit
  2. Hi, first of all here are my specs: Acer Aspire 5750G Intel Core i7 2630QM 4GB DDR3 RAM nVidia GeForce GT 540M Optimus Intel HD 3000 Integrated Graphics 640GB HDD I was mucking around with the BIOS and managed to disable the nVidia card and allocate no VRAM to the Intel HD Graphics hence turning off both graphics cards... So now my laptop does not show any screen, I have tried restoring the BIOS with a USB and FN + ESC but that did not work. As I have been trying to re-install the BIOS I think I may now have a corrupt one. I am now looking at shorting the CMOS Jumper but not sure how and if this will work?! I have found diffrent threads online saying to do this with a screwdriver and others not to use one. I'm wondering what other peoples view is on this, as currently I have no system!!! Thank you
