Firmware set for the XMA1901-YN platform on Wistron board 19723-1, including both the system BIOS and KBEC files. KBEC refers to the keyboard and embedded controller firmware that handles power button, battery charging and keyboard scanning. The 4.14 MB RAR lets you reflash both chips with a programmer when the board shows no power or corrupted firmware. Wistron uses this numbering style for its notebook boards. Back up each chip first and confirm the image sizes match before writing.
