To toggle between the rated processor speed and the compatibility speed while the system is running in real mode, press
<Ctrl><Alt><\>. (For keyboards that do not use American English, press <Ctrl><Alt> <#>.)
CPU ID(s)
CPU ID(s) provides the manufacturer's identification code for the installed processor(s).
Integrated Devices
Integrated Devices configures the devices integrated into the system board. Press <Enter> to configure these options.
Sound
Sound determines whether the integrated audio controller is On (the default) or Off. When Sound is set to Off, no sounds are
emitted from any attached external speakers or from the on-board speaker, except for beep codes. Set Sound to Off if you want to
use a sound expansion card instead of the integrated audio controller or if you need the resources used by the controller.
NIC
Network Interface Controller (NIC) determines whether the integrated NIC is set to On, Off, or On with PXE. The default is On,
which means that the NIC is enabled but not set to boot the system remotely from a network server.
Mouse Port
Mouse Port enables or disables the system's built-in Personal System/2 (PS/2)-compatible mouse port. Disabling the mouse allows
an expansion card to use interrupt request (IRQ) 12.
For more information about built-in ports, port designations, IRQs, and the remapping of ports, see "
Serial Port 1 and Serial Port 2
Serial Port 1 and Serial Port 2 configure the system's built-in serial ports. These options can be set to Auto (the default) to
automatically configure a port, to a particular designation (COM1 or COM3 for Serial Port 1; COM2 or COM4 for Serial Port 2), or
to Off to disable the port.
If you set a serial port to Auto and add an expansion card containing a port configured to the same designation, the system
automatically remaps the built-in port to the next available port designation that shares the same IRQ setting as follows:
COM1 (input/output [I/O] address 3F8h), which shares IRQ4 with COM3, is remapped to COM3 (I/O address 3E8h).
COM2 (I/O address 2F8h), which shares IRQ3 with COM4, is remapped to COM4 (I/O address 2E8h).
NOTE:
When two COM ports share an IRQ setting, you can use either port as necessary, but you may not be able to
use them both at the same time. If the second port (COM3 or COM4) is also in use, the built-in port is turned off.
For more information about built-in ports, port designations, IRQs, and the remapping of ports, see "
Parallel Port
Parallel Port configures the system's built-in parallel port. This option can be set to 378h (the default), to alternate addresses 278h
or 3BCh, or to Off to disable the port.
