BIOS package for Compal board LA-8481P, revision 1.A, containing two images according to the name: a 4 MB file and a 2 MB file, which suggests the board uses two separate SPI flash chips. Flash each image to the chip of matching capacity with a hardware programmer, since an image larger than the chip will not fit. Compal uses the LA-xxxxP numbering. Dump both original chips before writing, and confirm that the revision on the PCB is 1.A.
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.

Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
