Import Precision T1700 drivers to boot images on SCCM 2007 with Dell Client Integration Pack 2.0

I hope you can help.  I am trying update an SCCM image deployment on our first Precision T1700 workstation.  I downloaded the T1700 cab, extracted the files and used the import driver wizard to create a new driver package. I ignored the bit in the wizard about adding drivers to existing boot images. I booted off the network card on one T1700 but I didn't get any list of OS deployment task sequences.  Is this because I haven't added the network card and mass storage drivers to the boot image?  If so what is the best way to go about this now?
