updating bios on a mini pc with no optical drive

Got a small Gigabyte Brix box running as a home server. The manufacturer site has a newer BIOS file but the instructions assume a full desktop. Can this be done from a USB stick, and what happens if power cuts out halfway?

USB stick is how it's normally done on those. Format it FAT32 and read the readme in the BIOS download, it says which method: either the flash utility built into BIOS setup (you pick the file off the stick) or boot to the EFI shell and run the script that comes with it. Power cut halfway can brick it. Small boxes like that usually don't have a backup BIOS chip, so recovery means a programmer or sending it back. Run it off a UPS if you've got one. It only takes a few minutes. Note your BIOS settings first. They often go back to defaults, and for a home server you'll want things like power on after AC loss set again.
