DOS Utilities
The process of updating a controller’s flash must be done carefully
to avoid rendering the controller inoperable. AFU is designed to be
easy to use with all the necessary safeguards to prevent a user from
accidentally damaging the controller’s flash contents.
Overview of the AFU
The AFU performs the following primary functions:
■ Update—Updates all the flash components on a controller with
the flash image data from a UFI file.
■ Save—Reads the contents of a controller’s flash components
and saves the data to a UFI file. This enables you to later restore
a controller’s flash to its previous contents should the need
arise.
■ Ve ri f y—Reads the contents of a controller’s flash components
and compares it to the contents of the specified flash image file.
■ Ve rs i on —Displays version information about a controller’s
flash components.
■ List—Lists all the supported controllers detected in your
system.
See Running the AFU on page B-4 for command details.
System Requirements
The requirements for AFU are as follows:
■ AFU runs under MS–DOS version 5.0 or later. It cannot run
from a DOS command prompt window under any version of
Windows.
You must shut down your operating system and reboot to DOS
to use the AFU. To start MS–DOS, boot from a bootable MS-DOS
floppy disk or from a DOS partition on a bootable drive.
■ AFU requires at least 8 MB of extended memory.
■ AFU does not run with any DOS extenders installed in memory,
such as EMM386.SYS and DOS4GW.
AFU does support HIMEM.SYS and is compatible with other
DOS drivers running under HIMEM.SYS
(for example,
SMARTDRV.SYS and SETVER.SYS).
