Sunip Kumar Mukherjee replied to Erkki Heldiggrisen Muhonen's question in TroubleshootingMy specs is: ASUS P5KPL-AM/PS motherboard, 2GB DDR2 RAM, Sparkle nVidia 9400GT, Intel Core2Duo E6600. I am booting Niresh-Mavericks ISO from a pendrive (transferred via Win32DMGR), and using iBoot to boot. It is showing the error "Kernel panic: Driver for ACPI not found". I have tried acpi=no flag, but doesn't work. I have tried disabling ACPI v2 and ACPI APIC as well. No luck. Can anyone help me out?
