Appendix D: Using the AFU for DOS ● 70IntroductionThe AFU is a DOS utility used to update, save, or verify the HostRAID controller’s firmwareBIOS.The AFU is easy to use and contains safeguards to prevent you from accidentally damaging theHostRAID controller’s flash contents. Still, you must be careful to use the AFU correctly,otherwise, you could render the HostRAID controller inoperable.The AFU is used to:● Update—Updates all the flash components on a HostRAID controller with the flash imagedata from a User Flash Image (UFI) file.The AFU updates the HostRAID controller’s flash by reading UFI files and writing them tothe controller’s flash components.Note: The UFI includes the HostRAID controller’s type, thereby ensuring that the AFUuses the correct file.● Save—Updates and verifies the BIOS image of the controller.● Verify—Reads the contents of a HostRAID controller’s flash components and compares itto the contents of the specified UFI file.● Version—Displays version information about a HostRAID controller’s flash components.● List—Lists all supported HostRAID controllers detected in your system.System RequirementsThe requirements for AFU are as follows:● MS–DOS version 5.0 or later. It cannot run from a DOS command prompt window underany version of Windows.Note: You cannot create a bootable floppy using Windows 2000.● At least 8 MB of extended memory.CompatibilityThe AFU has the following compatibility issues:● Supports HIMEM.SYS and is compatible with other DOS drivers running underHIMEM.SYS (for example, SMARTDRV.SYS and SETVER.SYS).● Does not support DOS extenders installed in memory, such as EMM386.SYS andDOS4GW.Running the AFU from the GUIThe easy way to run the AFU is to use its GUI. If you prefer to run the AFU from the commandline, see Running the AFU from the Command Line on page 71.
