MasterHouse Posted December 9, 2008 Share Posted December 9, 2008 Hello, After installing OSX86 only one core of my quad cpu is working. Do I need a mod BIOS? Can anyone please explain in plain english what I have to do? Thanks a lot.

MasterHouse Posted December 9, 2008 Author Share Posted December 9, 2008 Problem solved. My boot problem was caused by a ps/2 keyboard so no need to use cpu=1. Thanks.

Dr Strangenotez Posted June 25, 2009 Share Posted June 25, 2009 Problem solved.My boot problem was caused by a ps/2 keyboard so no need to use cpu=1. Thanks. could you elaborate on how this issue was solved? I'm having the same issue, and I have to use a ps/2 keyboard to enter in any boot parameters (seems my usb kb doesn't work during boot but is fine once it gets to the login screen) I need those cores!
