Small BIOS file for a DOEL-2603 device with board marking X80C, version 3.0, supplied as a 512 KB ZIP. The name gives little else, so no ODM or chipset can be confirmed from it. An image of this size usually suits a 4 Mbit flash chip and would not fill a larger part correctly. It is intended for writing with an SPI programmer to recover a unit with corrupted firmware. Match the X80C marking and version on the PCB, keep a copy of the original chip contents, and compare sizes before flashing.
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.
