Chapter 2 Installation and Configuration
• ExpressCard WAKE#
1
—This setting enables or disables an ExpressCard device’s ability
to wake a soft off system. The default value is Disabled.
• PXIe Backplane WAKE#—This setting enables or disables a PXI Express peripheral
module’s ability to wake a soft off system. The default value is Disabled.
• SMBus ALERT#—This setting enables or disables a System Management device’s ability
to wake a soft off system by asserting the ALERT# signal. The default value is Disabled.
ExpressCard Configuration Submenu
Note This submenu is available on the PXIe-8840 ExpressCard variant only.
Use this submenu to apply alternate settings to the ExpressCard configuration. These settings
determine how much memory space, I/O space, and PCI bus numbers is pre-allocated for the
ExpressCard port, allowing non-PCI Express-aware operating systems to support hot-plugging
ExpressCard devices. Normally, you do not need to modify these settings, as the factory default
settings provide the most compatible and optimal configuration possible.
• ExpressCard Resources—This setting enables or disables the setting of the Reserved
Buses, Reserved Memory, and Reserved I/O settings. The default value for this setting is
Enabled. If this setting is disabled, the bus, memory, and I/O options disappear from this
submenu. Disabling this setting effectively sets Reserved Buses to 0, Reserved Memory
to 0M, and Reserved I/O to 0K.
• Reserved Buses—This setting determines the number of PCI buses reserved by the BIOS
for ExpressCard PCI-PCI bridges that may be hot-plugged in the ExpressCard slot. The
default value for this setting is 8 PCI buses.
• Reserved Memory—This setting determines the amount of memory space, in bytes,
reserved by the BIOS for PCI-PCI bridges that may be hot-plugged in the ExpressCard slot.
The default value for this setting is 64M bytes of memory.
• Reserved I/O—This setting determines the amount of I/O space, in bytes, reserved by the
BIOS for PCI-PCI bridges that may be hot-plugged in the ExpressCard slot. The default
value for this setting is 4K bytes of I/O space.
PCI Configuration Submenu
Use this submenu to apply alternate settings to PCI devices. Normally, you do not need to
modify these settings, as the factory default settings provide the most compatible and optimal
configuration possible.
• PCIe Max Payload Size—This setting determines the maximum payload size of
PCI Express devices. Valid options are Auto and 128 Bytes. The default value is Auto,
which allows the BIOS to choose an optimal value based on which devices are present.
