BIOS dump for a Dell 7450 all-in-one, packed in a RAR archive, with IPKBL-TP named as the board code and a 16 MB flash size stated. A 16 MB image corresponds to a 128 Mbit SPI chip, typically written with a hardware programmer after the board fails to POST or the firmware is corrupted. Extract the archive, confirm the chip on your board is 16 MB and that the board code matches, and read and save the original contents first so service tag and unique data are not lost.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @biosarchive. Enginerys does not host this file.
