High CPU utilization may occur when installing or running Microsoft Windows Server 2008* R2 or Microsoft Windows* 7 with default NIC driver for Intel® Gigabit ET Dual Port Server Adapter E1G42ET and Intel® Gigabit ET Quad Port Server Adapter E1G44ET Problem There has been high CPU load observed when installing or running Microsoft Windows Server 2008* R2 or Microsoft Windows 7* with default NIC (Network Interface Card) driver for Intel® Gigabit ET Dual Port Server Adapter E1G42ET and Intel® Gigabit ET Quad Port Server Adapter E1G44ET. Implication When the ports are not electrically "linked" and the embedded driver is loaded, the DPC rate steadily increases until the system slows to the point where it is essentially unusable. Status This issue may be fixed in a future driver release. Workaround None. 15. Intel® LAN driver installation failure on Microsoft Windows* 7 Problem The Intel® LAN driver version 16.8 and below may not be installed sucessfully on Microsoft Windows 7* with the .bat installation scripts in the driver package. Implication The LAN driver can not be installed by the .bat installation scripts in the driver package. Status The issue is fixed in Intel® LAN driver version 17.1 Workaround Two workarounds are availalbe: 1. The LAN driver can be manually installed. 2. User can lower the "User Account Control" to "Never Notify", then the driver can be installed with the .bat installation scripts. 16. Hard drives connected through SAS expander can't be detected in legacy mode Problem If hard drives are connected through expander to SCU ports and configured under RSTe mode, the hard drives can't be detected by system in legacy mode (default BIOS setting). Implication Users can't use the hard drives connected through expander as boot device to install OS. But users can install OS to other hard drives which are not connected through expander and load RSTe driver to make the hard drives connected through expander visible to OS. Or users can change Boot Options > EFI Optimized Boot to "Enabled" in BIOS Setup so that hard drives connected through expander can be detected by the system. 8
