BIOS image named R0190Y5 in ROM format, 2 MB in size. The alphanumeric code looks like a firmware build identifier rather than a model name, so the target device and board number cannot be determined from the file name. A 2 MB image fits a 16 Mbit SPI flash device. Before using it to recover a board with a programmer, compare its internal strings against a dump of the original chip. Keep that backup safe, because machine-specific data such as MAC or serial information may live there.
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 @bios_laptop. Enginerys does not host this file.
