Raw 2 MB BIOS image in FD format for Inventec board 6050A2293301-MB-A01. The name calls it a final fixed version that has been confirmed working, but it does not name the laptop model. An FD file is a full flash descriptor image that can be written directly to an SPI chip with a programmer. The size suits a 2 MB (16 Mbit) flash, so check the chip marking first, save the original dump, and confirm the board number on the PCB.
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 @freeschematicdiagram. Enginerys does not host this file.
