All to adapt to Microsoft who couldn't make 64bit UEFI boot loader in time (or so I heard)... I heard though that newer (Linux) versions of Intel Compute Stick would have 64bit UEFI but I'm not sure. > > I never did try FreeBSD on BayTrail but for running Linux on BayTrail I >> used special built Grub that was 32bit but could load 64bit OS.

That will boot a 64bit grub that should be able to boot a 64bit OS. http://liliputing.com/2013/10/booting-ubuntu-asus-transformer-book-t100.htm= l I do have customized Arch Linux memstick image with Grub and this booti32.efi image so it boots on these systems. This can be used to install a Grub bootloader that maybe can boot FreeBSD. One question is, would Grub's filesystem drivers for FreeBSD work in this mode? Maybe I should give it a shot today.. > >> On Tue, Mar 1, 2016 at 5:20 PM, John Baldwin <jhb@freebsd.org >> <mailto:jhb@freebsd.org>> wrote: >> >> On Sunday, February 28, 2016 07:00:06 AM Joe Holden wrote: >> > Hi all, >> > >> > Apologies if this is the wrong list... >> > >> > Is there any plan to support booting FreeBSD on 32bit UEFI systems >> (with >> > or without 64bit kernel/userland)?
