[MinnowBoard] RTL8111 with Legacy BIOS

Hi Eric,
I am building my OS in Platform Builder, I have used the same image to load
multiple Baytrail boards from different vendors (Adlink, Congatec, etc..).
The image loads, it's just the driver for the NIC that is failing (I
suspect the driver is attempting to access a memory location that was found
by the PCI enumeration which is an incorrect address). If I know the
physical location on the PCIe bus (along with memory addresses) I can see
if the PCI enumeration driver for Windows CE is faulty, or if there is some
other issue.
Thanks,
Emir
