 This installs Daisuke Aoyama's isboot kernel module, which allows
 booting FreeBSD directly from an iSCSI root disk. If your BIOS
 supports iSCSI you may configure your target settings in the BIOS
 and boot directly. If not, you may PXE boot using software that
 contains iSCSI support such as iPXE. The module reads the iSCSI
 Boot Firmware Table (IBFT) to configure the network and re-attach
 the volume once the kernel begins execution.
