FreeBSD 10.2-RELEASE UEFI hangs upon booting with install media.

[CeDeROM]

There are several setup options for your motherboard/bios/uefi, you may be
interested in compatibility modes for uefi vs legacy for disks and devices.
These caused problems for me.

Also you can boot in legacy mode, install in uefi mode, then boot the os
with uefi mode. Remember to create dedicated fat partition 100MB in size
then dd it with efiboot, so you can boot your FreeBSD in uefi :-)
