    The current iBFT specification and the current code (this push) includes the
    ability to specify the location of the iBFT table using the standard ACPI table
    mechanism, which is required on UEFI machines supporting iBFT, and which I
    would encourage non-UEFI machines to also use where possible. Obviously some
    systems, especially BIOS-based machines doing iSCSI boot on expansion cards,
    have difficulty with this, so we're not planning on de-supporting the old
    memory scanning method.

    Obviously, a major malfunction has occurred.
