    PC EFI is by far the best Emu Project I have heard of for a long time.

    Netkas: this is really fantastic. Thumbs up for that standing work…

    Thanks, xi

    The kexts load well…..but after loading NullCPUPowerManagement.kext……It is showing
    “Invalid Front-Side Bus Frequency 45Hz…
    Disabling the CPU….”…
    How to fix this problem? Does it mean my machine can’t run Mac?

    Motherboard: Intel DG41RQ1
    Processor : Intel Core 2 Duo
    Hard Disk : Samsung 500GB
