I had another thread on the issue of Intel 82567 LM Gigabit NIC and PXE not detecting the drivers. However the exact problem and fix only applied to the Toshiba M10. Here is the resolution to this issue:
Symptom: You have applied the right drivers for the Intel 82567 LM Gigabit NIC and still in PXE you cannot get it to recognize the drivers...
NicInfo returns - Vendor: 8086 Device: 4232
Problem: One of our other admins added the Intel drivers for an Intel 82567 LM-3 Gigabit NIC which also included drivers for the Intel 82567 LM Gigabit NIC. PXE however had problems with multiple inf files being added for multiple card types. With or without my own driver injection using only the files needed forthe Intel 82567 LM Gigabit NIC, PXE would not pick up the network drivers.
Solution: We removed the injection for Intel 82567 LM-3 Gigabit NIC and rebuilt it using only the files necessary. We then injected the drivers for the Intel 82567 LM Gigabit NIC and everything worked.
