Field Description
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.
