About this board
Files for the B340 CIH77S V1.0 motherboard.
Compare the board number printed on the PCB (near the RAM slots or under the battery) with the files before you flash. This listing is for revision 2.1; another revision of the same board can need a different file.
Files usually needed for this board
- BIOS (full SPI chip dump, .bin)
- EC / KBC firmware, if the board uses a separate EC chip
- Schematic (PDF)
- Boardview (.brd / .bdv / .cad)
Usually needed when the laptop powers on with a black screen after a BIOS update, is stuck in a boot loop, or is locked with a BIOS password.
Back up the original dump first — it contains machine-specific data (serial, UUID, MAC, ME), and you will want it if anything goes wrong.
