About these files
- BoardView overlays component designators on the PCB layout so you can probe the right nets.
- Sumita / board PDF packages are printable board maps used alongside schematics during rework.
- Tools point at free viewers and utilities we recommend; hosted binaries are files NLCRC has rights to publish.
- Always match board revision before flashing BIOS or replacing power ICs. Wrong ME / EC regions brick boards.
