Appendix D: Using the Adaptec Flash Utility for DOS ● 80
Introduction
The AFU is a text-based DOS utility used to update, save, or verify your HostRAID controller’s
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.

HIMEM.SYS (for example, SMARTDRV.SYS and SETVER.SYS).
