After cloning MAC adress on my Ethernet adapter Intel 82577LC, the error PXE-E05 occured (in OS windows 8.1 the ethernet adapter was with yellow exclamation mark and led on the adapter had blinked).
I found in the internet the solution, using IBAUTIL in MS-DOS mode to set default configuration .
After setting to default by using "IBAUTIL -NIC=1 -devcfg" my adapter is down.
No one LED blinks and in the device manager is not found (only wifi is found).
I tried once again to use IBAUTIL, but there write error "No supported network adapters found".
In BIOS I tried to set diffirent configuration, defaults settings, but still the network adapter is not found.
I tried also to remove battery for 10 minut, but nothing happened.
Could you mind help me with this problem.
