BIOS dump in .rom format for the Dell Latitude 3400, with board number 17938-1 in the name, a pattern used by Wistron, the ODM behind many Dell boards. The 16.0 MB size matches a 128 Mbit SPI flash, so it is likely a full chip image. Technicians write such dumps with an SPI programmer to revive a board with corrupted firmware. Match the board number printed on the PCB, back up the original chip because it holds the service tag and system data, and verify after writing.
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 @schematiclaptopramkushwaha. 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 →
