Modified BIOS for the Sony VAIO SVF152A29V on Quanta board DA0HK9MB6D0 revision D, marked as working and unlocked, with ModBios 025DA in the name, in a 5.72 MB ZIP. DA0xxxMBxxx is the Quanta numbering pattern. Unlocked images usually remove a BIOS password or expose hidden settings, and are written to the SPI flash with an external programmer. Save the original chip contents before writing, as they hold serial and licence data. Check the board revision and that the image fits the flash size.
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.
