IBM MT 2369 Maintenance Manual page 47

For some possible configurations of the computer,
PC-Doctor might not run correctly. To avoid this problem,
you need to initialize the computer setup by use of the IBM
BIOS Setup Utility before you run PC-Doctor. On the IBM
BIOS Setup Utility screen, press F9, Enter, F10, and then
Enter.
Note: When you initialize the computer configuration,
some devices are disabled, such as the serial port.
If you test one of these devices, you will need to
enable it by using PS2.EXE.
PC-Doctor cannot be used to test a device that is in the
docking station, even if the computer supports the docking
station. To test a USB device, connect it to the USB
connector of the computer. To test the Ultrabay device,
install it in the Ultrabay Slim slot of the computer.
Creating the PC-Doctor diagnostics diskette
In X40 series, the PC-Doctor disk can be created by
using the Access IBM Predesktop Area.
To create the PC-Doctor disk from the Access IBM
Predesktop Area, do as follows:
1. Enter the IBM Predesktop application by
pressing the Access IBM button during POST.
2. When the Access IBM application finishes
loading, double-click the "Create Diagnostic
Diskettes" icon.
3. It will take about 15 seconds to authenticate the
digital signature, and then the ThinkPad
computer will reboot into PC-DOS.
4. A batch file will automatically start up to prompt
the user through creating the boot diskettes. The
user will be informed how many diskettes will be
needed.
a. The user will be prompted to insert each
diskette in sequence.
b. Typically, the user only needs to press the
Enter key for the proper floppy drive to
format and create the diskette.
c. Each diskette will be erased and formatted
with the PC-Doctor DOS boot image.
5. Once all the diskettes have been created, the
ThinkPad computer will reboot. The user is
asked to remove all diskettes from the drive, or
to insert the first diskette created if it is desired
to run the diagnostics.
