Setup Password lets you restrict access to your computer’s System Setup program in
the same way that you restrict access to your system with the system password fea-
ture. The settings are:
‡
Not Enabled (the default)
‡
Enabled
‡
Disabled by Jumper (jumper removed)
NOTE: Read “Using the Setup Password Feature” found later in this chapter for
instructions on assigning a setup password and using or changing an existing setup
password. See “Disabling a Forgotten Password” found later in this chapter for
instructions on disabling a forgotten setup password.

Mouse enables or disables the system’s built-in Personal System PS/2-compatible
mouse port. Disabling the mouse allows an expansion card to use IRQ12.

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 particu-
lar 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 interrupt request (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).
NOTE: When two COM ports share an IRQ setting, you can use either port as neces-
sary,
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.

Parallel Port configures the system’s built-in parallel port. Parallel Port can be set to
378h
(the default), to alternate addresses 278h or 3BCh, or to Off to disable the port.
NOTE: Do not set Parallel Port to 278h if you have an Extended Capabilities Port (ECP)
device connected to the port.
