• Force IGD Primary —This setting determines how the BIOS
prioritizes video controllers when external video cards are present in
the system. During POST, only one device can act as the video display
device. When set to
Enabled , the BIOS allows the integrated graphics
device to remain the video display device. When set to Disabled , the
BIOS allows an external graphics card, if present, to act as the default
video display device. Note that even when set to
Disabled , the
integrated graphics device still acts as the video display device if it is
the only one available in the system. The default setting is
Disabled .
• 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.
• I/O —This setting determines the amount of I/O 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 4096 bytes of I/O space.
• 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.
