Factory BIOS for the Dell Inspiron 5400 all-in-one, with IPTGL-CL shown as the board identifier, suggesting a Tiger Lake platform board. The archive is a ZIP and the name marks it as a factory image rather than a user-extracted update. Such dumps are written to the SPI flash with a hardware programmer when the machine fails to POST after a bad update. Dump and save the original chip first, keep the service tag data, check the PCB identifier matches, and confirm the file size equals the chip capacity.
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.
How to open a .zip file
Compressed archive that every operating system opens without extra software.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
