Device Manager and Windows Disk Management but no actions can be

performed. This issue is only apparent in systems operated without an Optical

Drive installed.

Status: Intel may fix this issue in a future BIOS release

Workaround: This device can be moved to the bottom of the boot order so that it doesn’t

impede the expected boot process. There is no workaround to prevent the

device from being reported to the OS.

34. High CPU utilization may occur when installing or running Windows

2008 R2/ Windows 7 with default NIC driver

Problem: There has been high CPU load observed when installing or running

Windows2008 R2/Windows 7 with default NIC (Network Interface Card) driver.

Implication: When the ports are not electrically "linked" and the embedded driver is loaded

the DPC (Deferred Procedure Calls) rate steadily increases until the system

slows to the point where it is essentially unusable.

Status: This issue was fixed in BIOS R0054. Before Operation System installation,

Change the BIOS setting Pcie AER support under Advanced -> PCI

configuration from “Enable” to “Disable”.

Workaround: Make sure the ports are connected to a network, switch or simply back-to-back.

This need to be done at least prior to the driver loading because once the port

is malfunctioning it cannot be recovered by connecting the ports. Updating to

the latest posted driver resolves the problem. The latest NIC driver 16.0 can be

obtained at below webpage.

35. Clearing BIOS CMOS in BIOS Revision R0042 May Return an Invalid

Date

Problem: If the user clears the BIOS CMOS settings via jumper or using the Sysconfig

/bldfs switch, the date in BIOS setup may be corrupted and read 09XX.

Implication: An invalid date stamp, 09XX, may be displayed in BIOS setup after clearing

BIOS CMOS settings using the jumper or the Syscfg utility resulting in the user

having to perform an extra reboot of the system to recover the date in the

proper format.

Status: This issue may be fixed in a future BIOS revision.
