What these files are for
A BIOS dump is a full image of the board's SPI flash chip. It is written back with an SPI programmer when the original firmware is corrupted, after a chip replacement, or to recover from a failed update. Read and save the original chip first: serial number, DMI data and the Intel ME / AMD PSP state differ between boards.
A schematic is the circuit diagram of the main board: power rails, power-up sequence, component values and net names. It is the reference for measuring voltages and tracing a fault.
EC (embedded controller) firmware runs the keyboard controller, power sequencing, battery charging and fans. Depending on the board it lives in a separate chip (ENE KB9012, ITE IT85xx, Nuvoton NPCE) or inside the main SPI image, so check which applies before flashing.
