Booting FreeBSD from the 5th SATA of a Microserver Gen8

The HP Microserver Gen8 when configured to disable RAID on the front loading bays (something you should do if planning on using ZFS) is unable to boot from the 5th SATA port, which is usually reserved for the front optical drive.

There are several workarounds, but the most popular one is installing a separate bootloader on an USB drive or MicroSD card, and from there load your OS of choice.

Preparing the drive

Grab your USB drive, create a MBR partition table and a FAT32 partition, and mark it
