Yes, your right Emmanuel, thanks.

That is not the code we build release images with, that is Warners tests for the boot loader. No, that's the actual code that generates boot1.efiffat. Warner Yup, and EFI have no problem at all with this. FAT12 can work with all EFI implementation, the problem is the size of the FAT12 part that sometimes causes problems.

Re: EFI booting from external USB pen drive
Bjoern, I had this problem earlier this week while using FreeBSD-12.0-CURRENT-amd64-20180628-r335760-memstick.img on my ThinkPad P50. I had used `dd` to place the img file on a partition (e.g. /dev/sdb1) of the USB pen drive and it wouldn't boot properly. After I used `dd` to place the img on the entire device (e.g. /dev/sdb), I noticed that it had its own partition scheme with three partitions, and that booted just fine.

I am not able to get anything that boots. What is the size for the fat12 partition ? Everything over ~30MB will fail. Go to fat16/fat32 with a size of 150MB just to be sure. On a Thinkpad (secure boot is off) from the “boot device chooser from ‘BIOS’” I get a quick blank screen and am back at the chooser. I’ve tried the gpart “thinkpad hack” as well as trying an MBR (why that should work I don’t know but the memstick one does) and GPT options of various kinds.
