3.3.6 Setting I/O Space for PCI Devices (2/2)
Select one of the following two assignment types and set the assignment in the
n
"Device Manager menu" of the UEFI.
* When auto assignment is used for some devices and forced assignment is used for other
devices in the same system, auto assignment is performed after forced assignment is set
(and a system reset is performed).
• Forced assignment of the I/O space
• Reserve an I/O resource for each of devices (including onboard devices such as IOUs) for I/O
resources and PCI Express cards that are included in a partition.
• This type of assignment is useful for assigning I/O space to specific devices and cards if
there are more than 16 devices that require the I/O space.
• Auto assignment of the I/O space
• This type of assignment is easy to use and can be used when the partition configuration is
relatively small and 16 or less devices require the I/O space.
For details, refer to "3.4 [Device Manager] Menu" in "Tool Reference".
