    Hi folks,

    I'm not sure if this is specifically related to 5570/10.5.1/Vista(Ultimate), but the event viewer is reporting ACPI errors

    AMLI: ACPI BIOS is attempting to read from an illegal IO port address (0x71), which lies in the 0x70 - 0x71 protected address range. This could lead to system instability. Please contact your system vendor for technical assistance

    Screenshot attached.

    Unfortunately, Parallels ACPI emulation is not full compliant with the ACPI standard. But Parallels developers team can confirm that this error would not affect Vista performance and stability. In the next version this issue will be fixed, because the ACPI emulation will be rewritten.
