# Foxconn D41S

This page describes how to run coreboot on the FOXCONN D41S desktop from FOXCONN. The D42S, D51S, D52S are compatible boards with the difference being the CPU.

## Building coreboot

The default options for this board should result in a fully working image:

    # echo "CONFIG_VENDOR_FOXCONN=y" > .config
    # echo "CONFIG_BOARD_FOXCONN_D41S=y" >> .config
    # make olddefconfig && make

The easiest to flash externally is to simply extract the SPI flash from its socket. To do this gently take the SPI flash out of its socket and flash with your programmer.

NOTE: Don’t forget to set the WP# AND HOLD# to 3V.

NOTE2: Make sure to reinsert it in the right direction afterward
