Sony VAIO EE series firmware read from a working machine, as the read ok note in the name suggests, saved as a 2.00 MB ROM file. Its size fits a 16 Mbit SPI flash chip, so it can go straight onto the chip with a hardware programmer. The name gives no board number or BIOS version, so compare the motherboard code printed on the PCB with the donor before use. Back up the existing chip, verify after writing, and note that system-specific data such as serial numbers may come from the donor unit.
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.
