A Broadcom firmware file is often not a simple binary. It is frequently encapsulated in Broadcom's proprietary format, which has a 92-byte header. The BCM2-utils suite (primarily for cable modems) includes tools like psextract that can analyze these file structures, showing things like load addresses, compression flags, and checksums. The header contains information such as: bcm63381b0 firmware full
