Using Altiris without using PXE at all

Altiris DS 6.9 (plan on installing SP1 next week)

I am being told by my network manager that I need to make Altiris work without using PXE. The reasoning being is he is trying to set up a Citrix Provisioning Server to use for Thin Clients and Virtual Workstations. That also uses PXE and he has it set up so if the computer is set to boot to NIC/PXE it automatically pulls an image from the provisioning server. I am unsure if I can make these work together in any way and since he read that you can use Altiris on computers that do not support PXE he is set on making it work that way. I have tried to do some experimenting with using WinPE and embedded automation but I am not having any success. Now the only thing I can think of it could be the computer I am using which is a Dell Vostro 1510. We are a Dell shop and have the following model computers in production:

-Optiplex GX260
-OPtiplex GX270
-Optiplex GX280
-Optiplex GX620
-Optiplex 740
-Optiplex 745
-Latitude D6xx Laptops
-Vostro 1400 and Vostro 1510 Laptops

There are a couple mix and match models but those cover the majority. The Altiris DS was set up months ago and never used as my Network Manager was originally in charge of getting this to work. Since that he has been busy with other projects it recently got re-assigned to me and I am pretty lost. My Net Admin insists it worked in his tests using PXE back in September but now that he setup that other PXE services for CITRIX Altiris is broken. I am not sure if I should uninstall PXE and leave it off or re-install it and try to make it work with the CITRIX PXE. Please help me.
