Hi.
Recently i have experienced problems with flashi bios in broken NAS server. 
Flahrom was able to detect the chip but couldn't do anything with it. 
Below is the output from the tool. Can you help me somehow or direct me the way to find solutuon myself?

Thanks!

Found Winbond flash chip "W25Q64.W" (8192 kB, SPI).
This chip may contain one-time programmable memory. flashrom cannot read
and may never be able to write it, hence it may not be able to completely
clone the contents of this chip (see man page for details).
