SOLVED Yesterday !!! Thanx Niresh you are the greatest !!!!!!
Just booting with boot flag -x, then the system is repairing itself..... Thanx!!!!
i installed Niresh Mavericks on my ASRock N68C-GS-FX on a SATA-HD with separate PCI-e AHCI-Controller (ASMedia). Installation was successfull with USBLegacyOff=Yes, after restarting from HD the PS/2-Mouse and the PS/2-Keyboard are switched off and Computer hangs up at world map, so i cant choose my country (at window with worldmap).
What can i do?
