Chapter 10: AT-Diag Utility

Starting the AT-Diag Utility
The AT-Diag utility is a quick and easy way for you to test the components
on the adapter, configure the speed and duplex mode of the port, and
enable or disable the BootPROM chip and MBA. But before you can use
the utility, there are a couple things you need to do.
The utility only works under MS-DOS. The system cannot be running
Microsoft Windows, Linux, or any other operating system. So the first thing
you need to do is determine whether the system where you want to run the
program has a DOS mode, in which it runs only MS-DOS. Refer to the
system’s documentation to determine whether this is possible and how to
access the mode.
If the system does not have a DOS mode, you can create a MS-DOS boot
diskette. There are web sites on the Internet with programs you can use to
create the disk. Simply follow their instructions. A boot diskette for
MS-DOS 6.22 will probably work for most systems.
If you are going to be using a boot diskette, you might need to change the
BIOS on your system so that it boots from the diskette drive instead of
from the hard disk. Refer to your system’s documentation for instructions
on how to access the BIOS. What you need to do is adjust the sequence
of hardware devices the system looks to for its operating system
whenever the unit is reset or power cycled. The diskette drive should
come before the hard disk drive.
The final step is to copy the diagnostic program files from the Installation
CD to a diskette or to create a driver installation diskette. When a system
is booted in DOS, the CD drive might not be accessible, making it
impossible for you to run the program from the Installation CD. The
program files are located in the \drivers\diagnos folder on the
Installation CD. There are three files. Be sure to copy all three files onto
diskette. You can store them in the root directory of the diskette. If you
prefer to use a driver installation diskette, refer to “Creating a Driver
Installation Disk” on page 68.
Once you have determined how to boot the system into DOS or,
alternatively, created a boot diskette, you are ready to run the diagnostics
program. To start the program, perform the following procedure:
1. Boot the system in DOS. If you are using a MS-DOS boot diskette,
insert the boot diskette into the diskette drive and reset the system.
Wait for the DOS prompt (A:) to appear.
2. If you copied the AT-Diag program files onto a diskette, remove the
boot diskette from the drive and insert the program diskette.
Otherwise, insert the Installation CD into the CD drive.
