If you're interested, you can try out the following ISO:
https://www.dropbox.com/s/srbunx0agrokcs3/freebsd-current-uefi-bios-amd64.iso
The image was built on Friday 8th of August for the amd64 platform.
I tested out the EFI part on VirtualBox (UEFI 2.X) and my MacBook Pro 17
inch from 2011 (EFI 1.10), and as far as EFI goes, I successfully booted
the image on both my Mac and VirtualBox (however, booting the image from
BIOS using my Mac was a different story).
So, as I said, as far as (U)EFI goes, the image should work on UEFI 2.X
based PC's and EFI 1.10 based Macs.

I'd point out that, as of last week, the standard -CURRENT ISOs (and
generate-release.sh script) make EFI-bootable media by default. All
the snapshots should have this done already, for instance.

I wasn't aware of that, but thanks for the info. :)

I also got a message like that when I booted from a USB stick on a

I fixed it by creating a custom ISO image and burned that onto a DVD
using an external DVD drive.
The UEFI installer boots fine from this external DVD drive.
Here is how I did it:
Genereste an ISO with the FreeBSD-CURRENT kernel, mount the ISO and
copy all files from the root directory in the ISO and unmount
> cd /usr/src/release
> sh ./generate-release.sh # You may have to run “make
buildworld” and be connected to the internet to install required ports.
> mount -t cd9660 /scratch/R/release/FreeBSD-something-disc1.iso
/mnt
> mkdir freebsd_generic_installer
#Files copied to the directory in the next command will be copied
to a new ISO in step 3
> cp -R /mnt/ freebsd_generic_installer/
> umount /mnt
2. Create a FAT filesystem image and place the loader in it in the
default path that UEFI will look for (the following steps are copied
from https://wiki.freebsd.org/UEFI#CD.2FDVD_Boot_under_UEFI):
> dd if=/dev/zero of=efiboot.img bs=4k count=100
> mdconfig -a -t vnode -f efiboot.img
> newfs_msdos -F 12 -m 0xf8 /dev/md0
> mount -t msdosfs /dev/md0 /mnt
> mkdir -p /mnt/efi/boot
> cp loader.efi /mnt/efi/boot/bootx64.efi
> umount /mnt
> mdconfig -d -u 0
3. Create the custom ISO image. Please make sure that the entry in
freebsd_generic_installer/etc/fstab matches the label you choose in
the command below.
> makefs -t cd9660 -o bootimage='i386;efiboot.img' -o
no-emul-boot -o rockridge -o label=“FREEBSD_UEFI_INSTALL" -o
publisher="test" uefi-test.iso freebsd_generic_installer/
To get the example in the command above to work, please make sure
that the entry in freebsd_generic_installer/etc/fstab reads
"/dev/iso9660/FREEBSD_UEFI_INSTALL / cd9660 ro 0 0"
4. Burn the image to DVD, reboot your system and choose “EFI Boot”.
Note that unless you are using a EFI console like rEFIt or rEFInd,
you may have to kind of wait a couple of minutes while the kernel is
loading before anything appears on the screen.

Hi,
On my MacbookPro11,3, I got this error message:

Yes, I got that in the mac laptops I tried, it worked on a Mac
Pro. It
might be the frame buffer corruption that Ed Maste was mentioning.
I purchased a new MacBook Air yesterday (model identifier
MacBookAir6,2). UEFI boot and vt(4) worked correctly. (My image
included Rafael's patch; I haven't tried a boot without.)
I also committed a change to display the framebuffer parameters
(address, dimensions, etc.) on boot, in order to help identify the
source of this issue. If you have a moment can you build a new USB
stick image and give it a try?
