More of a concern though is that above this struct is this... /* Define the 32 Bit Mode Command Control Block (CCB) structure. The first 40 bytes are defined by and common to both the MultiMaster Firmware and the FlashPoint SCCB Manager. Is it safe to change this if the firmware/3rd party sw is expecting it to be a u32 ? Dave
