Situation:

When trying to use Ghost 8.0 in a PXE boot environment, you see the error message "No DPMI Memory" when the Ghost executable attempts to load.

Solution:
When you create a TCP/IP network boot image or TCP/IP Network Ghost client boot image using the Ghost Boot Wizard, it is created with an allocated size of 16 MB. Some computers and network cards cannot handle network boot images of this size. The solution to this issue is to create a smaller, custom TCP/IP boot image using the 3Com Boot Image Editor. These instructions assume that you already have 3Com Boot Services installed at your location. If this is not the case, install 3Com Boot Services before proceeding.

• Extract the files from the existing boot image
• Create a custom TCP/IP Network Boot Image
• Insert the appropriate files into the new boot image

1. Open the 3Com Boot Image Editor, and click "Edit an existing file..."
2. Select your existing network boot image (created with Ghost Boot Wizard), and click Open.
   You should see several files and two folders: one called NET and the other called GHOST.
3. Select all files, and click the Extract button.
4. Browse to a convenient location to save these files (like an empty folder on the desktop), and click OK.
5. Double-click the NET folder.
6. Select all of the files in this folder, and click Extract.
7. Save them to a folder called NET in the same location in which you saved the previous files.
8. Repeat this process with the files in the GHOST folder.
9. Click Close.
   You should now be back at the 3Com Boot Image Editor screen.

• Ibmio.com
• Ibmdos.com
• Command.com

1. In the 3Com Boot Image Editor, click "Create a TCP/IP or PXE image file."
2. In the "Create TCP/IP Image File" window, in the "Image file name" box, specify a location and name for the image file you are about to create.
   Remember to include the .sys extension when naming the file.
3. Ensure that the Source Drive selection shows the correct drive letter for the floppy drive. The default selection is drive A.
4. Under Capacity, select "Extended Capacity" and click 4 in the drop-down list.
   This sets the allocated space of the image file at 4 MB.
5. Under Options, check "Writeable" and "Pre-OS."
6. Click Advanced.
7. Check both boxes, and click OK.
8. Insert the system floppy disk into the floppy drive, and click OK to create your TCP/IP image file.

1. In the 3Com Boot Image Editor, click "Edit an existing file."
2. Select the file you just created, and then click Open.
   The only files you should see in your boot image at this point are Command.com, Io.sys and Msdos.sys. If you have any additional files, select them and click Delete.
3. Click Add.
4. Browse to the files that you extracted in the first section of this document.
   You may need to change the "Files of type" drop-down menu to "All Files (*.*)" in order to see the files that you extracted.
