BIOS image for the Sony VAIO VGN-CS230J laptop in the Intel GMA 4500MHD integrated graphics configuration, stored as a 1.00 MB binary. The graphics note matters because VAIO models of this line were also sold with discrete GPUs, and the firmware differs between variants. The 1 MB size corresponds to an 8 Mbit SPI chip.
