disneytoy Posted April 12, 2010 Share Posted April 12, 2010 Hello! I can't seem to get beyond the boot screen (switch to Snow Leopard DVD, F5 (various combinations of arguments -x -v -f busratio=21 cpu=1 fsb=133). I have tried about 10 different boot CDs, you name it. MSI P55-GD55 4GB ram, Galaxy GT240, Sata DVD, Sata HD. 1.3 latest bios, ACHI set etc. I'd just like someone knowledgable to tell me, if the 4 failed kexts in the panic screen are from the BOOT CD, or files from the Retail SN DVD? I can't get to the Install screen. see attached screen shot. But these are the reported errors I get: Failed to load kext com.psystar.driver.OpenhaltRestart Couldn't alloc class "AppleACPIPlatformExpert" Couldn't alloc class "UUID" Couldn't alloc class "es_osx86_EvOreboot" Couldn't alloc class "com_psystar_OpenHaltRestart" panic(cpu - caller 0x55aa33): "Unable to find driver for this platform: \"ACPI\".\n"@/Extra/builds/xnu/xnu-1456.1.26/iokit/Kernel/IOPlatformExpert.cpp:1393 Debugger called: <panic> Backtrace (CPU 0), Frame : Return Address (4 potential args on stack) Kext es.osx86.driver.EvOreboot - library kext com.apple.kpi.iokit not found.
