BIOS archive for the Dell OptiPlex 5270 All In One with motherboard code IPCFL-BH. The 10.3 MB RAR should hold a firmware image for the board SPI flash, useful when the machine is dead, stuck on a black screen or bricked by an interrupted update. Write it with an external programmer such as CH341A or RT809H. Before flashing, compare the board code on the PCB, back up the existing chip, and make sure the image size matches the capacity of the flash memory fitted.
