Casper laptop BIOS for the A15PG model with the name noting .303 and a Pegatron-made board, packed in a 1.38 MB 7z archive. Pegatron is the ODM behind several Casper notebooks. A technician uses such an image to rewrite the SPI flash with a programmer when the machine does not boot, beeps or stays on a black screen after a failed update. Read and keep the original chip contents first, and confirm the extracted file size matches the flash chip before writing, as a mismatched image will not fit.
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 @biosfiles. Enginerys does not host this file.
