Wakeup On LAN
Wakeup On LAN determines whether the Wakeup On LAN feature is set to On or Off. You must reboot
your system before a change takes effect.
Sound
Sound determines whether the integrated audio controller is On or Off. You must reboot your system before
a change takes effect.
NIC
NIC determines whether an integrated network interface controller (NIC) is On or Off. You must reboot your
system before a change takes effect.
Mouse
Mouse enables or disables the system’s built-in PS/2-compatible mouse port. Disabling the mouse allows
an expansion card to use IRQ 12.
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).
Likewise, COM2 (I/O address 2F8h), which shares IRQ3 with COM4, is remapped to COM4 (I/O
address 2E8h).
NOTES: 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.
If you are using the Microsoft® Windows® 95 or IBM® OS/2® operating system, you cannot use both
serial ports at the same time.
Parallel Port
Parallel Port configures the system’s built-in parallel port. This option can be set to 378h (the default), to
