Dump in .bin format, 1.00 MB, labelled DV5A, indicating a DV5 model with an A suffix that the name leaves unexplained. No board number, revision, chipset or firmware version is included. The size corresponds to an 8 Mbit SPI flash, so check the chip marking before programming. A technician would use it to recover a machine with a corrupted BIOS by writing it with an external programmer. Read the original chip first and keep that backup, and confirm the PCB board number matches the donor board.
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 @biosfilebins. Enginerys does not host this file.
How to open a .bin file
A raw, byte-for-byte image of a flash chip: the main BIOS / UEFI, the embedded-controller (EC) firmware, or both.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
