Does it actually boot via a UEFI, or did UEFI fall back to CSM and do a legacy boot?

The .iso building was updated to create hybrid boot images some time back, these .iso images should be usable as boot .iso on a cd/dvd and as memstick images. I would encourage there use over the memstick images, as there is a plan to remove them once we get better experience with the hybrid .iso. It is also possible that something has munged the boot in head. Have you tried a downloaed ^/head snapshot from the last week, as it could also be your build system that is not producing a proper boot image? > /Johannes -- Rod Grimes rgrimes@freebsd.org
