The wiki is being retired!

Documentation is now handled by the same processes we use for code: Add something to the Documentation/ directory in the coreboot repo, and it will be rendered to Contributions welcome!

This page describes how to use coreboot on the Jetway NF81-T56N-LF mainboard.

This page is a work in progress. Rows with (WIP)* are high-priority ticket items and shall be addressed soon.

ACPI is still being worked on, however due to the nature of ACPI it may take some time to get this right.

  • AMD Fusion G-series AMD Fusion G-T56N (1.65 GHz dual core) APU
  • AMD A55E part of the chipset, AMD A55E (Hudson-E1) southbridge
  • F71869AD Fintek F71869AD Super I/O
  • RTL8111E Twin Realtek RTL8111E network controllers
  • VT1705 6-Channel HD Audio (via VIA VT1705), AC97 AD/DA


The NF81-T56N-LF is a IPC form factor embedded board:

  • AMD Fusion G-T56N (1.65 GHz dual core) APU
 - 2x SO-DIMM sockets for DDR3 800-1066 SDRAM (1.5 or 1.35V)?
 - VGA and LVDS (via Analogix ANX3110)
  • AMD A55E (Hudson-E1) southbridge
 - 6x USB 2.0/1.1 ports
 - 5x SATA3 6Gb/s, 1x mSATA socket
 - 6-Channel HD Audio (via VIA VT1705)
 - PCI and ISA (via ITE IT8888)??
 - NEC uPD78F0532 microcontroller on I2C ("SEMA")??
  • 2x RJ45 GbE (via Realtek RTL8111E x2)
  • Fintek F71869AD Super I/O
 - PS/2 KB/MS port
 - RS232 header (via Unisonic UTC 75232 RS232 driver/receiver)
 - GPIO header
 - CIR header
  • 1x MXIC MX25L1606E (SO8, soldered) 16 Mbit SPI flash (BIOS)

Note: MX25L1606E is 16Mbit, 8bits in a byte, so 2MB. Jetway *lies* claiming the SPI flash is 16MB. They also use red pen over the chip so you wont see this deceit.
