Main BIOS and EC firmware set for the HP 430 notebook with the CHICAGO_CP_HPC_MV_MB_V2 board, stored in a RAR archive of about 1.98 MB. It looks like a copy of a similar MAIN+EC pack, so compare checksums if you already have one. Use the system image for the SPI BIOS chip and the EC image for the embedded controller flash, which governs power-on, battery charging and keyboard. Always dump the existing chips before programming, and confirm the board marking reads MV_MB_V2 so the firmware fits this layout.
