Main-board BIOS for the Sony VAIO VPCF13WFX, referencing the M932 board designation used on the VAIO F series. The =4= token in the name is not explained. The RAR is about 4.28 MB and is meant for restoring firmware on the SPI flash when the laptop fails to start or shows a corrupted BIOS. Open it with any RAR-capable archiver, check which chip the image belongs to, back up the current contents with your programmer, and make sure the image size matches the flash before writing.
