Working BIOS dump for the Dell Vostro 13 5310 laptop on board 203009-1, marked as fully working. The six-digit number with a dash suffix follows Wistron's numbering, so Wistron is the board maker. The 10.5 MB RAR should contain the SPI image for recovering a dead or boot-looping unit with an external programmer. Make sure the PCB carries the same board number. Dump and keep the original chip contents first, since Dell stores the service tag and other system data in flash.
