Is the efi partition FAT? An EFI system partition (ESP) is a FAT-formatted partition with a specific GPT or MBR identifier and file system hierarchy; EFI firmware will try to load /EFI/BOOT/BOOTX64.EFI from the ESP. boot1.efi is an EFI application - that is, a PECOFF format binary. It searches for a UFS filesystem and loads loader.efi from that. It is intended to simplify the UEFI boot process, so that loader.efi, the .4th files, loader.conf etc. do not all need to be installed in the ESP. boot1.efifat is a FAT filesystem image that contains a copy of boot1.efi as /EFI/BOOT/BOOTX64.EFI. It exists so that the installer can treat it as opaque bootcode, like other boot schemes. It's certainly possible to create a partition, use newfs_msdos to format it, and copy in boot1.efi instead. > It is one disk, dedicated to FreeBSD (a laptop disk).

Better user-facing documentation is in progress; for now the best source is probably the wik.Received on Tue Sep 16 2014 - 19:32:33 UTC
