For Intel® Desktop Boards that support Intel® Active Management Technology (Intel® AMT):
If you set Wake on LAN from S5 to Stay off, Microsoft Windows* detects an Intel Virtual CD and an Intel Virtual Floppy. See images.
These virtual devices also appear in the BIOS Boot menu, in the selection list for CD/DVD-ROM Drive Order.
The drives, related to the Intel® AMT, are inaccessible drives and are seen only at the first cold boot. If you restart Windows, they disappear. However, if you shutdown and restart the PC from a cold boot, they reappear.
The virtual devices appear because power to the Intel AMT chip is provided if Wake on LAN is enabled. The system then believes that Intel AMT is turned on, even if it is not. Therefore it is looking for AMT components and tries to enable them. If Intel AMT is not enabled, the components are not accessible.
To eliminate these virtual devices:
- During boot, enter the BIOS setup by pressing F2.
- In the Power menu, set Wake on LAN from S5 to Power On.
- Press F10 to Save and Exit.
