BIOS image for Compal board LA-D451P revision 1.0, with project codes BIUS1, S2, Y0 and Y1 listed, suggesting it covers several variants. The archive is about 4.6 MB. Compal uses the LA-xxxxP numbering for boards it builds for various laptop brands, and the brand is not named here. Match the number and revision on the PCB, read and save the original SPI flash before writing, and check that the image size suits the chip in use.
