Dell Driver CAB files for Enterprise Client OS Deployment

Hello All,

Just joined the community to see if I could find the information that I need for deployment of an OS Image, to two Enterprise Class Dell Desktop machines. We have Optiplex 745 and Optiplex 755 models that I cannot find, in the matrix on the page http://en.community.dell.com/techcenter/enterprise-client/w/wiki/2065.dell-driver-cab-files-for-enterprise-client-os-deployment.aspx , a reference to either of the two models I am searching for. Perhaps these two models fall under a specific model group, but I cannot tell where or in which group these models would fall into.

Please help, as I would like to prepare a WinPE imaging tool for use on these models, and having the Network Drivers and the Mass Storage Device Drivers found in the correct Driver CAB File, would make a world of difference!
