Lenovo Z410 BIOS dump of 4 MB, marked as OK in the name, meaning it was reported working. The Z410 is known to use two flash chips in some configurations, and this 4 MB image is the larger one, with a separate 2 MB file for the smaller chip. Write it with an SPI programmer to the matching 32 Mbit flash when the laptop is dead or stuck at a black screen. Check which chip position it belongs to, confirm capacity and board number, and save the original contents before programming.
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.
