BIOS Setup
Onboard Serial Port 3
This is used to select an I/O address for the onboard serial port 3.
However,
if the LCD Display Panel supports touch screen,
leave this
field in its default setting because the touch screen is internally
connected to COM 3 therefore a default address has already been
assigned to this port. Make sure COM 3 is not attached with a
serial device.
Onboard Serial Port 4
This is used to select an I/O address for the onboard serial port 4.
Serial Port 1 Use IRQ, Serial Port 2 Use IRQ, Serial Port 3 Use IRQ
and Serial Port 4 Use IRQ
These fields are used to select an IRQ for the onboard serial port 1,
2, 3 or 4.
