LAN Boot – [Disabled] or [LAN1]
This field allows you to boot the system over one of the Ethernet connections (LAN1, J23).
Refer to Appendix B, LAN Boot Feature and the BIOS settings for the integrated PXE Boot
Agent for more information.
∗ If this field is set to [LAN 1], the LittleBoard 800 will boot from Ethernet 1 (J23). If you
enable LAN Boot [LAN 1], you will need to save changes and reboot the system, before
going to the PXE BIOS settings. Refer to Appendix B, LAN Boot Feature for more
information.
• On-Board Serial Ports

Serial Ports 1 and 2 can not share the same IRQs, and the IRQs used
for Serial Ports 1 and 2 can not be used for Serial Ports 3 and 4 and
vice versa.

Serial 1 – [Disabled], [3F8h], [2F8h], [3E8h], [2E8h], [260h], [3E0h], [2E0h], [200h], [220h],
[228h], [238h], or [338h]
This field specifies the base address used for Serial Port 1.
•
IRQ – [none], [1], [3], [4], [5], [6], [7], [9], [10], [11], [12], [14], or [15]

IRQ is assigned, making it available for other devices.
•
Mode – [RS-232] or [RS-485]
This field specifies the signal mode, RS232, or RS485, used for Serial Port 2. If [RS-485]
mode is selected, the RTS signal should be used to control the direction for this port
(transmit or receive).
♦
