PC-Doctor for DOS
The PC-Doctor for DOS diagnostic program is used to test hardware components of your server. It is also
used to report operating-system-controlled settings that interfere with the correct operation of your server. If
you are unable to isolate and repair the problem yourself after running the PC-Doctor for DOS diagnostic
program, save and print the log files created by the PC-Doctor for DOS diagnostic program. You will need
the log files when you speak to a Lenovo technical support representative.
You can download the latest version of the PC-Doctor for DOS diagnostic program from
http://www.lenovo.com/support. The PC-Doctor for DOS diagnostic program runs independently of the
Windows operating system. Use the PC-Doctor for DOS diagnostic program if you are unable to start the
Windows operating system. You can run the PC-Doctor for DOS diagnostic program from a diagnostic
disc that you created.
Creating a diagnostic disc
This section provides instructions on how to create a diagnostic disc.
To create a diagnostic disc, do the following:
1. Download a self-starting bootable CD/DVD image (known as an ISO image) of the diagnostic program
from http://www.lenovo.com/support.
2. Use any CD/DVD burning software to create a diagnostic disc with the ISO image.
Running the diagnostic program from a diagnostic disc
This section provides instructions on how to run the diagnostic program from a diagnostic disc that you
created.
To run the diagnostic program from a diagnostic disc that you created, do the following:
1. Make sure the optical drive you want to use is set as the first boot device in the startup device sequence.
2. Make sure the server is turned on and then insert the disc into the optical drive. The diagnostic
program opens.
Note:
You can insert the disc into the optical drive when you are setting the startup device sequence.
However, if you insert the disc into the optical drive when you have already entered the operating
system, you need to restart the server to access the diagnostic program.
3. Follow the instructions on the screen to select the diagnostic test that you want to run.
Note:
