When
applied
At next boot Specify the upper limit of link speed for PCI
slot.
2.5GT/s: Let the slot work at 2.5GT/s.
5.0GT/s: Let the slot work at 5.0GT/s.
8.0GT/s: Let the slot work at 8.0GT/s.
When
applied
At next boot Enable or disable the power-saving feature
(Active State Power Management) for PCI
device. When this feature is enabled, the process
to reset PCIe link is performed by OS. By this, a
correctable error may occur on PCIe Link,
however, this is not an error. You can continue
the normal operation.
Disabled: Disables the power-saving feature to
PCI device.
Auto: Makes the power-saving feature to PCI
device to the highest level within the allowable
range.
Force L0s: Makes the power-saving feature to
PCI device to "L0s" state.
OSPM: Setting of power-saving feature to PCI
device depends on OS.
At next boot Enable or disable MMIOH (Memory Mapped I/O
Space over 4GB).
Disabled: Disables the feature.
Enabled: To be enabled when I/O card that
supports MMIOH is used.
At next boot Specify whether the fixed PCI bus number is to
be assigned to PCI card at BMC failover.
This item is displayed only for other than
Express5800/A1040b.
Enabled: The same PCI bus number is assigned
to PCI card before and after failover. Use this
setting if you are using Linux OS.
Disabled: The different PCI bus number is
assigned to PCI card before and after failover.
Use this setting if you are using an OS other than
Linux.
At next boot Enable or disable the feature to skip allocation of
Legacy I/O Space for the specific PCI card. Set
this item to Enabled unless the allocation of
Legacy I/O Space is required specifically.
Enabled: Enables the feature. Legacy I/O Space
cannot be allocated to the specific PCI card.
Disabled: Disables the feature. Legacy I/O Space
can be allocated to the specific PCI card as well
as the normal PCI card.
