Working BIOS dump for the Acer Predator Triton PT515-52 laptop on board 19813-1, marked fully working. The five-digit number with a dash suffix follows Wistron's board numbering, so Wistron is the board maker for Acer here. The 15.6 MB RAR likely contains the full SPI image used to recover a unit with no display or a firmware fault. Flash it with a CH341A or similar programmer after confirming the board number on the PCB, and keep a full read of the original chip.
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.
