Second numbered copy of a Sony EE read marked OK, stored as a 2.00 MB .rom binary. No model, board number or revision appears in the name, so you must match the source device by other means. A 2 MB size fits a 16 Mbit SPI flash, common for BIOS chips. Open it in a hex editor or programmer software to look for model strings before use. Always read and save the original chip twice and compare the reads before erasing and flashing this image to a Sony board.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @biosarchive. Enginerys does not host this file.
