BIOS .bin 1.00 MB Shared

1 MB firmware binary named d531, which most likely refers to the Dell Latitude D531 notebook, although the name carries no brand, board number or version to confirm it. A 1 MB image corresponds to an 8 Mbit SPI flash chip. Such a dump is written with a hardware programmer to restore a laptop with corrupted BIOS. Because the identification is uncertain, compare the chip type and board markings carefully, read and archive the original chip contents, and verify the write before reassembling the machine.
