BIOS dump for a board identified as A14SGT1 with motherboard number 14033-1, a pattern typical of Wistron-made laptop boards. The name gives a 16MB image, which means a 128 Mbit SPI flash chip. The RAR is about 9.6 MB, so extract it and check the image size against the chip before writing. Use a programmer such as a CH341A or RT809H, and save a full read of the original chip first. That backup keeps the serial number, MAC address and ME data recoverable if the new image fails.
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.
