OS: Netware 6.5
Board: Gigabyte GA-EG45M-DS2H with Realtec 8111C chip

I downloaded from Realtek the drivers for
10/100/1000M Gigabit Ethernet > PCI Express > Software > RTL8111B/RTL8168B/RTL8111/RTL8168/RTL8111C
This contains RTGESRV.lan and RTGESRV.LDI

When autodetecting, hdetect proposes this drives himself. Although when trying to load it says: "invalid load file format NOT NLM"

What does this means & where should i look further.

Thanks !!
