BIOS and EC firmware pair for the Sony VAIO VPCCB series, board MBX-239 revision 1.1. MBX is Sony's internal numbering for VAIO mainboards. Because the embedded controller image is included, the archive helps when the fault is no power or no charging, as well as with a corrupted system BIOS. Make sure the revision on the PCB reads 1.1 before you flash. Read out both original chips with a programmer first, and check that each file size matches the flash it is intended for.
