Insyde BIOS image for the Sony VAIO VPCSB31FD notebook, with R2087H4 shown as the firmware version in the name. It is a raw .rom dump of 2.50 MB, which is an unusual size, so it may be a partial or region dump rather than a whole chip image. Compare it with the capacity of the board's SPI flash before programming. Such files are used to recover units with a corrupted BIOS or a forgotten password. Back up the original chip contents first, because Sony stores model-specific data in flash.

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.
