Working firmware set for the LCH-1 E-GPU board, number 213015-1, which follows Wistron's six-digit board numbering. The name lists two chips, U2601 and U8102, so the 27.7 MB RAR likely holds separate images, one for each flash device. Program each image to the chip with the matching reference designator using an SPI programmer. Read and save both originals first. Confirm that the board number on the PCB matches and that each image size equals its target chip's capacity.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @biosarchive. Enginerys does not host this file.
