Guide to Update BIOS Using a BIN File

Q: Can I update the BIOS using Windows if the laptop still boots?
A: Yes, but you need the official EXE updater from the manufacturer. The .bin file in this guide is for hardware programmers only.

Q: My EA40-CX has an IT8587E EC – does the BIOS contain EC firmware?
A: Often yes. Make sure your clean dump includes the EC region; otherwise, keyboard/touchpad/fan control may fail.

Q: I flashed a new BIOS, but now I have no WiFi / incorrect serial number.
A: You need to use a HEX editor to copy your original DMI (Data Region) from the old backup into the new BIOS. Look for offsets: 0x1000 to 0x1FFF (varies by version).

  • Verify file size and timestamp against vendor documentation.
  • If possible, ask vendor support to confirm the appropriate image for your board serial number/revision.

    • Because the EA40-CX is an OEM board, the official manufacturer website may not list this specific board ID.
