Onboard Floppy Controller

This option controls the legacy disk controller.
Option Description
Disabled Disabled turns off all legacy diskette drives.
Enabled Enables the on-board legacy diskette controller.

Serial Port1 Address

This option specifies the base I/O port address and Interrupt Request address of serial
port 1. The Optimal setting is 3F8/IRQ4. The Fail-Safe default setting is 3F8/IRQ4.
Option Description
Disabled Set this value to prevent the serial port from accessing any system resources. When this option is
set to Disabled, the serial port physically becomes unavailable.
3F8/IRQ4 Set this value to allow the serial port to use 3F8 as its I/O port address and IRQ 4 for the
interrupt address. This is the default setting. The majority of serial port 1 or COM1 ports on
computer systems use IRQ4 and I/O Port 3F8 as the standard setting. The most common serial
device connected to this port is a mouse. If the system will not use a serial device, it is best to set
this port to Disabled.
2F8/IRQ3 Set this value to allow the serial port to use 2F8 as its I/O port address and IRQ 3 for the
interrupt address. If the system will not use a serial device, it is best to set this port to Disabled.
3E8/IRQ4 Set this value to allow the serial port to use 3E8 as its I/O port address and IRQ 4 for the
interrupt address. If the system will not use a serial device, it is best to set this port to Disabled.
2E8/IRQ3 Set this value to allow the serial port to use 2E8 as its I/O port address and IRQ 3 for the
interrupt address. If the system will not use a serial device, it is best to set this port to Disabled.

Serial Port2 Address

This option specifies the base I/O port address and Interrupt Request address of serial
port 2. The Optimal setting is 2F8/IRQ3. The Fail-Safe setting is 2F8/IRQ3.
Option Description
Disabled Set this value to prevent the serial port from accessing any system resources. When this option is
set to Disabled, the serial port physically becomes unavailable.
3F8/IRQ4 Set this value to allow the serial port to use 3F8 as its I/O port address and IRQ 4 for the
interrupt address. If the system will not use a serial device, it is best to set this port to Disabled.
2F8/IRQ3 Set this value to allow the serial port to use 2F8 as its I/O port address and IRQ 3 for the
interrupt address. This is the default setting. The majority of serial port 2 or COM2 ports on
computer systems use IRQ3 and I/O Port 2F8 as the standard setting. The most common serial
device connected to this port is an external modem. If the system will not use an external
modem, set this port to Disabled.
Note:
port address and IRQ 4 for its interrupt address. This requires that the Serial Port2 Address be
set to Disabled or another base I/O port address and Interrupt Request address.
3E8/IRQ4 Set this value to allow the serial port to use 3E8 as its I/O port address and IRQ 4 for the
interrupt address. If the system will not use a serial device, it is best to set this port to Disabled.
2E8/IRQ3 Set this value to allow the serial port to use 2E8 as its I/O port address and IRQ 3 for the
interrupt address. If the system will not use a serial device, it is best to set this port to Disabled.
