This field allows you to reverse the hardware drive letter assignments of

your floppy disk drives. Configuration options: [No Swap] [Swap AB]

Floppy Disk Access Control [R/W]

When set to [Read Only], this field protects files from being copied to floppy

disks by allowing reads from the floppy disk drive but not writes. The setup

default [R/W] allows both reads and writes. Configuration options: [R/W]

[Read Only]

Onboard Serial Port 1 [3F8H/IRQ4], Onboard Serial Port 2 [2F8H/IRQ3]

These fields allow you to set the addresses for the onboard serial connec-

tors. Serial Port 1 and Serial Port 2 must have different addresses. Con-

figuration options: [3F8H/IRQ4] [2F8H/IRQ3] [3E8H/IRQ4] [2E8H/

UART2 Use Infrared [Disabled]

When enabled, this field activates the onboard infrared feature and sets the

second serial UART to support the infrared module connector on the moth-

erboard. If your system already has a second serial port connected to the

onboard COM2 connector, it will no longer work if you enable the infrared

feature. See IrDA-Compliant Infrared Module Connector in 3.8 Exter-

nal Connectors. Configuration options: [Disabled] [Enabled]
