Installing FreeBSD 10.0 on an UEFI PC

[Stéphane Dupille]

Hello,

I'm trying to install FreeBSD 10.0 on a PC, but unfortunately it has a 
UEFI bios.

Here is a complete dmesg output :

First, I tried to install using a GPT partition, but the BIOS, even in 
Legacy mode, is unable to find the bootcode into the GPT partition.

Here is the BIOS setup:
Launch CSM                       Enabled
Boot option filter               Legacy only
Launch PXE OpROM policy          Legacy only
Launch storage OpROM policy      Legacy only
Other PCI device ROM priority    Legacy OpROM
Network stack                    Disabled


The install script into a GPT partition is here :
https://cloud.dupille.org/public.php?service=files&t=e56cbf708be34311adf097b1e64eb823

I've read somewhere that the Bios is too dumb, and when it finds a GPT 
partition, it assumes that the only option to boot is from a UEFI 
script, and refuses to launch bootcode.


Then, I tried to install FreeBSD using a MBR partition. But for several 
reasons, I want to install it on ZFS. So I followed instructions found 
here :
https://wiki.freebsd.org/RootOnZFS/ZFSBootPartition

The install script I'm using is :
https://cloud.dupille.org/public.php?service=files&t=e2b2ee0e6ea2882fd6392008970e565c

   disk=ada
   disknum=1
   device=${disk}${disknum}
   # Now we crate partitions
   gpart create -s mbr $device
   gpart add -t freebsd $device
   gpart create -s BSD ${device}s1
   gpart set -a active -i 1 ${device}
   gpart add -t freebsd-zfs ${device}s1
   # bootcode
   zpool create -O mountpoint=none -o altroot=/mnt zroot 
/dev/${device}s1a
   zpool set bootfs=zroot zroot
   gpart bootcode -b /boot/boot0 $device
   dd if=/boot/zfsboot of=/tmp/zfsboot1 count=1
   zpool export zroot
   gpart bootcode -b /tmp/zfsboot1 /dev/${device}s1
   dd if=/boot/zfsboot of=/dev/${device}s1a skip=1 seek=1024



But when I boot, All I get is :
F1  FreeBSD
F5  drive 1

F6 PXE
Boot: F1


And then, nothing happens.

What could I do now ?

I still have the option to install it on a UFS partition (it boots 
fairly well on the USB memstick), but I'd rather have ZFS.


Regards,
