BIOS dump for a laptop mainboard with the ILYGA project code, board LA-N211P revision 1A, packed as a RAR archive. The name states a 32MB flash image, so the target SPI chip should be a 256-megabit part. The LA-xxxxP numbering follows the Compal pattern, and Compal builds boards for several laptop brands. Before writing it with a programmer such as a CH341A or RT809H, confirm the board number and revision printed on the PCB, save a backup of the original chip, and check that the extracted image size matches the 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.
