Introduction

firmware BIOS and Non-Volatile Random Access Memory (NVRAM).
The AFU is easy to use and contains safeguards to prevent you from accidentally damaging the 
HostRAID controller’s flash contents. Still, you must be careful to use the AFU correctly, 
otherwise, you could render the HostRAID controller inoperable.

any version of Windows.
