Seeking PXE driver for HP Compaq Elite 8300

I am trying to find the PXE driver for a HP Compaq Elite 8300, I get the following error message:

PCI\VEN_8086&DEV_1502&SUBSYS_1495103C&REV_04

The message directs me to a Elite 8200 SFF and Intel(R) 82579LM Gigabit Network Connection

I have visited the HP driver store and tried all of the I217-LM drivers, and 82579-LM drivers. both Vista 32 (if available) Win7 32bit

I am on a schools RM Education network which uses a build process similar to SCCM and WDS, but requires a PXE driver, usually a Vista 32 driver

Thank you
