    I'd like to be able to use the EFI shell, and test EFI images on this system.

    At one point, it seemed that this was common ( http://feature-enable.blogspot.com/ describes this from before VT was enabled in more recent BIOS versions). However, I can't even get the sample method described in that post to work.

    I am using BIOS 2.31 ( with "Intel"[0x21A=1] and "Full"[0x85=5] menus enabled in setup )
    I've tried across 5 different USB keys, including a sandisk cruzer (as per the thread), each formatted to FAT32.
    In each case the BIOS tries to boot DOS off the images (if the partition is Bootable), or gives a "No bootable partition" message otherwise.

    A thread in the Sony forums claims that some Insyde versions have UEFI locked down -- can anyone confirm this is the case? I tried the workaround from that thread, disabling the SATA controllers, but with no luck. The BIOS does claim (with "Full" menus enabled) that UEFI booting is Enabled (this is the default state).
