I have MotherBoard ASUS P5GC-MX/1333 in the link below :
Every thing was working fine (XP Prof SP3) till my mate upgraded the BOIS after that Onboard LAN Adapter got missing from the Device Manager and the LAN icon got missing from my "Network Place".
I did a fresh installation of windows still the same problem is going on, then I realized the problem with BOIS.
I have checked BOIS and I enabled every thing that I would have thought is related to onboard LAN but still no joy.
What should I do to rectify the problem
