Compressed copy, 864 KB as a ZIP, of the BIOS for the Sony VAIO VGN-CS230J with Intel GMA 4500MHD integrated graphics. Extract it to obtain the flash image, expected to be 1 MB for this machine. Program it into the SPI chip with an external programmer to revive a board with corrupted firmware. The graphics variant is important, since discrete-GPU versions of the series use different firmware. Back up the board's current chip, and check that the extracted size equals the chip capacity before writing.
