Boardview for Wistron board 14279-1, packed in a 229 KB RAR. BDV stands for boardview, used with tools such as OpenBoardView or FlexBV to locate parts, nets and test points on both sides of the PCB. It is especially useful for finding which components sit on a shorted rail or where a signal can be probed. Wistron uses this five-digit dash-revision pattern for many Dell notebooks. Make sure the PCB number matches 14279-1 before relying on part locations.
