Symantec GHOST stalling in DOS

I am attempting to run Symantec Ghost 7.5 in DOS from a client of a mapped server (with Ghost.exe on). I am using a Dell Optiplex GX270. Doing this on any earlier Dell systems works fine, Ghost loads in DOS and allows me to create an image of the client on the mapped server. However on the Dell GX270 system, Ghost does not run or freezes on the first screen.

Any help would be greatly appreciated as I am planning to do many Dell GX270 replicas.
