Dell Inspiron 22-3263 all-in-one BIOS, version 1.9.0, supplied as a raw .bin image packed in a 4.91 MB ZIP archive. The name gives no motherboard number, so match the image against the board actually fitted in the unit before use. A file like this is normally written to the SPI flash with a programmer such as a CH341A when the system will not start or the firmware is corrupted. Always dump and keep the existing chip contents first, since they hold the service tag and other unit-specific data that a generic image lacks.
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 →
