Kevin Oberman, Network Engineer > E-mail: kob6558@gmail.com The gpart bootcode command is quite apart from and unrelated to (as far as I can tell) the EFI partition. I think the EFI partition is supposed to be the first partition on a GPT-partitioned disk. I have installed FreeBSD to a USB stick, GPT-partitioned with three partitions: boot, root and swap. I used gpart bootcode command to make the USB stick bootable, there was no EFI partition in this case. This is good if FreeBSD is the only OS installed to a disk. EFI partition is to allow sharing a hard drive with multiple OS installations. Tom
