BIOS file for the Foose board, number 07236-2, with the extra code 4X703 in the name, packaged as a 1.02 MB ZIP. BRCM-5761 points to the Broadcom BCM5761 Ethernet controller, so this may be a LAN controller firmware rather than the main system BIOS. Check the contents before use. The numbering follows Wistron's scheme. Program it with an SPI programmer after reading and saving the existing chip. Also confirm that the PCB number matches and that the image size suits the target memory.
