Sony VAIO SVE111B BIOS dump on motherboard MBX-272, with V181 likely the firmware version. MBX is Sony's own board numbering system. The 1.85 MB RAR is meant for reprogramming the SPI flash with an external programmer when the notebook will not boot or has a damaged BIOS. Make sure the MBX-272 label on the PCB matches, save a full backup of the existing chip, which can hold model and serial data, and check the image size matches the chip.
