Working BIOS for board IQ57 / IQ57N revision 1.0, containing images for the U4 and U5 chips as indicated by the name, in a 3.63 MB RAR. Two designators suggest separate flash devices, so check which file belongs to which chip position on the PCB before programming. Such dumps are written with an external SPI programmer to recover a board with corrupted firmware. Read and back up both original chips first, and confirm each image size matches the capacity of its target chip.
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.

Compressed archive — the usual wrapper for a schematic + boardview pair or a BIOS + EC set.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
