BIOS archive for the Dell Vostro 2520 with an Intel Core i3, on the DV15 MLK Wistron mainboard 11280-1. Wistron numbering uses this five-digit code with a dash suffix, visible on the board silkscreen. The 2.90 MB RAR is meant for restoring corrupted firmware by writing the SPI flash through a programmer, either desoldered or with a test clip. Before writing, confirm 11280-1 on the PCB, back up the original chip because it keeps service tag data, and check the dump matches the chip size.
