System Security Screen
Table 1-6 lists new options for the PowerEdge 1950 III system.
NOTE:
Systems that are shipping in China are not equipped with TPM.
CAUTION:
Before enabling the TPM Security option, ensure that the operating
system supports TPM.
I/OAT DMA
Engine
(Disabled default) Enables or disables the I/O Acceleration Technology (I/OAT)
option. When set to Enabled, I/OAT reduces system CPU
usage for applications that use TCP by offloading part of TCP
receive operation to the DMA engine.
System Interrupts
Assignment
(Standard default) This field controls the interrupt assignment for PCI devices
in the system. When set to Distributed, interrupt routing is
swizzled to minimize IRQ sharing among devices.
Table 1-6. New System Security Screen Options
Option Description
TPM Security
(Off default) Sets the reporting of the Trusted Platform Module
(TPM) in the system.
When set to Off (default), presence of the TPM is
not reported to the operating system.
When set to On with Pre-boot Measurements, the
system reports the TPM to the operating system and
stores the pre-boot measurements (compliant with
Trusted Computing Group standards) to the TPM during
POST.
When set to On without Pre-boot Measurements, the
system reports the TPM to the operating system and
bypasses pre-boot measurements.
