FreeBSD provides for booting from both the older MBR standard, and the newer GUID Partition Table (GPT). GPT partitioning is often found on computers with the Unified Extensible Firmware Interface (UEFI). However, FreeBSD can boot from GPT partitions even on machines with only a legacy BIOS with gptboot(8).
UEFI eliminates this limitation by defining standard interfaces for memory management. In UEFI boot mode, boot devices use these interfaces to request memory space from the BIOS memory manager. When a system contains multiple boot devices, UEFI boot mode allocates memory on-demand for each device’s firmware.

1. Introduction Secure boot provides a way to ensure that only authorized EFI binaries are loaded by a computer's firmware. This ensures that no malicious code can run before the operating system is loaded. This document describes one method of securing FreeBSD's boot process. FreeBSD's regular UEFI boot process has two stages: boot1.efi and loader.efi.
Bootable UEFI memory stick. To test UEFI booting on a memory stick, create a GPT partition table with a small EFI partition and the rest of the space dedicated to a FreeBSD UFS partition: gpart create -s gpt da0 gpart add -t efi -s 800K da0 gpart add -t freebsd-ufs da0 dd if=/boot/boot1.efifat of=/dev/da0p1 newfs /dev/da0p2.
