MSI MS-17E91 BIOS & EC

BIOS .rar 18.1 MB Shared

BIOS and EC firmware for the MSI board MS-17E91, a laptop mainboard in MSI's MS-17xx notebook numbering, packed in an 18.1 MB RAR. Having both images helps when the laptop will not power on, fails to charge or shows no display. The BIOS goes to the SPI flash and the EC firmware to the embedded controller, each written with a suitable programmer. Back up the original chips before writing. Match the board number on the PCB, and confirm each image size fits its target chip.
