Working BIOS for the Dell OptiPlex 3050 all-in-one, from the motherboard labelled IPKBL-SR, delivered as a 7.58 MB RAR archive. The KBL part of the code likely refers to the Kaby Lake platform, but the name does not confirm the CPU. Technicians use such a dump to recover an AIO that does not POST after a failed update or flash corruption. Write it with an external SPI programmer after saving the original image, which holds the service tag. Verify that the image fits the flash chip.
