Main BIOS firmware for the Acer Predator PT917-71, marked EH78F and version 1.07, provided as an 8.77 MB RAR. The Main label suggests the primary system BIOS image rather than an EC file, though the archive contents should be checked. It can be used to reprogram the SPI flash on a board that does not POST after a failed update. Read the existing chip with a programmer and keep the backup, then make sure the image size matches the flash capacity before writing.
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.
