BIOS for the Dell Inspiron 24-3477 all-in-one desktop with the IPKBL-PS motherboard, a Kaby Lake platform board name. The 5.20 MB RAR is meant for restoring firmware when the AIO stays dark, fails to POST or was damaged by an interrupted update. It is normally written to the board's SPI flash with an external programmer. Verify the board marking matches, check the flash capacity against the image size, and read the original contents first so the service tag data can be kept.
