About this board

This thread is for the INPRIRON 5402 with main board 19861-1.

Wistron board numbers are 5–6 digits plus a revision. Check the number printed on the PCB before you download.

What this thread covers
  • BIOS (full SPI chip dump, .bin)
  • Schematic (PDF)
  • Boardview (.brd / .bdv / .cad)

Common cases: dead board after an interrupted BIOS update, ME region errors, missing serial number or UUID after a board swap, or a password lock.

Before flashing, always read and save the original chip. It holds the serial number, UUID, MAC address and ME data for that exact machine.

If you have a working file for this board, please share it below. More files: search 19861-1 in File Finder.
