♦ USB Boot Support – [Disabled] or [Enabled]
This field allows you to select a USB device as a boot device. Refer also to Drive
Assignment settings, Boot Order settings, and USB (device enable) under On-Board
Controllers for the USB Drive settings and the number of USB ports enabled, respectively.
* If this field is set to [Disabled], none of the USB devices connected to the ReadyBoard
800 can be used as a boot device.
* If this field is set to [Enabled], any of the bootable USB devices connected to the
ReadyBoard 800 can be used as a boot device.
NOTE Ampro does not recommend connecting a USB boot device to the
ReadyBoard 800 through an external hub. Instead, connect the USB
boot device directly to the ReadyBoard 800.
♦ LAN Boot – [Disabled] or [LAN 1]
This field allows you to boot the system over the Ethernet 1 connection (LAN 1, J16). Refer
to LAN Boot in Appendix C, LAN Boot Feature for more information.
* If this field is set to [LAN 1], the ReadyBoard 800 will boot from Ethernet 1 (J16). If you
enable LAN Boot for [LAN 1], you will need to reboot the system and go to PXE agent
BIOS settings. Refer to Appendix C, for more information.
