BIOS ROM for the Sony VAIO VPCEE23FX, a model in the VPCEE series. The name gives no board number, revision or status. The 2 MB size matches a 16 Mbit SPI flash chip, and a .rom raw image loads into programmer software like a .bin. Sony boards carry an MBX number on the PCB, which should be checked against other VPCEE dumps before use. Back up the original chip, write with a hardware programmer, and verify the written data afterward.
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 @biosbigarchives. Enginerys does not host this file.
How to open a .rom file
A BIOS image as shipped by the vendor (commonly AMI) — often the BIOS region only, without descriptor or ME.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
