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 feature. The options are: Not Enabled (the default option) 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 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 categories can be set to Auto (the default option) 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). 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. Parallel Port configures the system's built-in parallel port. This category 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 Enhanced Capabilities Port (ECP) device connected to the port. Using the System Setup Program 4-9

the same way that you restrict access to your system with the system password fea-
ture. The options are:
²
Not Enabled (the default option)
²
Enabled
²

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

enables or disables the system’s built-in PS/2-compatible mouse port. Dis-
abling 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 cate-
gories can be set to Auto (the default option) 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:
²
COM1 (input/output [I/O] address 3F8h), which shares IRQ4 with COM3, is
remapped to COM3 (I/O address 3E8h).
²
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. This category 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 Enhanced Capabilities Port (ECP)
device connected to the port.
