function with this option set to either Analog or DVI. The DDC
communication path is only enabled when set to Analog for an analog
monitor, so certain advanced features of your analog monitor may only

ExpressCard Hot-Plug Resources—This setting determines whether
or not resource pre-allocation is Enabled or Disabled for the
ExpressCard port. When this setting is Enabled, the BIOS will
pre-allocate memory space, I/O space, and PCI bus numbers for the
ExpressCard port, allowing non-PCI Express-aware operating systems
to support hot-plugging ExpressCard devices. When this setting is
Disabled, no resources will be pre-allocated, and you may need to
restart the OS when hot-plugging an ExpressCard device. The default
setting is Enabled.
•
Hot-Plug Bus Gap—This setting determines the number of PCI buses
that will be reserved by the BIOS for ExpressCard PCI-PCI bridges
that may be hot-plugged in the ExpressCard slot. This setting is only
applicable if ExpressCard Hot-Plug Resources is set to Enabled.
The default value for this setting is 8 PCI buses.
•
Memory—This setting determines the amount of memory space, in
bytes, that will be reserved by the BIOS for PCI-PCI bridges that may
be hot-plugged in the ExpressCard slot. This setting is only applicable
if ExpressCard Hot-Plug Resources is set to Enabled. The default
value for this setting is 32 megabytes of memory.
•
Pre-fetchable Memory—This setting determines the amount of
pre-fetchable memory space, in bytes, that will be reserved by the
BIOS for PCI-PCI bridges that may be hot-plugged in the ExpressCard
slot. This setting is only applicable if ExpressCard Hot-Plug
Resources is set to Enabled. The default value for this setting is
32 megabytes of pre-fetchable memory.
