add -split=500 to client side options to split image files into 500 MB segments to save on CDs. Note naming conventions. The name you provide is used for the first segment, '1' is appended to the second segment, '2' to the third segment etc.
Note that Ghost will split images into 2GB segments due to DOS limitations anyway. Use Explorer to list the contents of the image directory.
Creating Ghost boot disk for loading from CD
To reverse the process and load the image to a disk from the CDs, use the Ghost Boot Wizard to create a boot disk with generic CD drivers.
You can eliminate the need for bootable diskette, create a bootable CD and copy the first segment to the CD.
