BIOS .bin 8.00 MB Shared

Full SPI flash read from an ASUS X550L series mainboard, specifically identified as X550LC with the XX032H configuration. The 8.00 MB size matches a 64 Mbit chip carrying descriptor, ME and BIOS regions. It is useful when reprogramming a board that will not post or loops on power-up. Since several dumps with this name exist, compare checksums between them. Save the original chip contents before writing and confirm the board revision on the PCB matches the donor.
