BIOS image for the Lenovo IdeaCentre AIO 330-20IGM all-in-one desktop, version O3SKT36A, stored in a 5.10 MB rar. The name gives no mainboard number, so match the system model and inspect the board label before use. Restoration with an SPI programmer is the usual route when an all-in-one stalls on a black screen after a failed update. Extract the archive, confirm the image size matches the flash chip on the board, and keep a full backup of the current chip contents before erasing and writing anything.
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.
