Go to the Advanced Menu->PCI Express Configuration Submenu.
For complete information on BIOS setup options, see the BIOS Operation section in the
back of this manual.
PCI Bus
ETXexpress COMs will continue to support legacy I/O devices. No PCI Express
components such as PCI plug-in cards are supported with the PCI 2.1, 32-bit interface.
PCI is a 32-bit or 64-bit bus, which is usually implemented as a 32-bit bus. It can run at
clock speeds of 33MHz or 66MHz. At 32 bits and 33MHz, it yields a throughput rate of
133 megabits per second.
Configuration
The BIOS automatically configures settings for the PCI bus. However, you can
configure support for the PCI bus from the BIOS Setup Utility. (Press the Delete button
during reboot to see the BIOS Setup Utility.)
Go to the PCI/PNP Menu for PCI BIOS options.
For complete information on BIOS setup options, see the BIOS Operation section in the
back of this manual.
Ethernet Ports
Type 3 ETXexpress COMs support an additional 2 GbE Ports. These ports have been
implemented in the ETXexpress-WPM using the Intel 82573L GbE controller chip. Each
82573L controller chip uses one PCI Express lane. Optionally, if the GbE ports are not
needed, then the board can be configured to free up the two PCI Express lanes that
support the controllers and re-route them to the baseboard. See the PCI Express sub-
section above for more information.
Configuration
The BIOS automatically configures settings for the 82573L controllers.
