Raw 2 MB BIOS dump for the Dell Studio 1555; the PM suffix is unexplained and may denote a board or chipset variant, so treat it with caution. The size corresponds to a 16 Mbit flash chip common on this generation. A technician uses it to restore a board with corrupted firmware by programming the chip with an external SPI programmer. Other Studio 1555 images exist for different variants, so confirm the board configuration, keep a backup of the original chip, and verify the size before writing.
