[MinnowBoard] UART and COM ports problem

[Anteja Vuk Macek]

Hi all,

On MinnowMax I work  on Windows 8.1 with UART.
   In BIOS Setup I enable UART.   In  LSS & SCC Configuration menu in BIOS
Setup I enable : LSS HSUART #1 Support  , LSS HSUART #1 FlowCtrl  , LSS
HSUART #2 Support  , and LSS HSUART #2 FlowCtrl .  But I don't know if I
need to in BIOS Setup in Miscellaneous configuration  set  UART interface
on  Super IO UART, for now I set  Internal UART for UART interface.
   I install Intel driver (
https://downloadcenter.intel.com/download/24228/Intel-embedded-drivers-for-Windows-8-1-32-bit-
)
and I got two UART controllers.

Problem :
  Problem is that I have only one COM port ( COM1)  and it is for
debugging.  I looking in inf (iaiouart.inf ) file of driver for which
device is , and I find APCI/INT33BC device.  The COM1 is device
APCI/PNP0501 .

What I need to do to get COM 2 device ?  I saw  BaseSerialPortLib 16550
module in  MdeModulePkg/Library for what it is this module.  Need I add
some module for UART or Serial port in fdf (PlatformPkg.fdf ) file to get
COM2 device, or add  COM2  in ACPI_table? Where I can find ACPI_table in
source of firmware?

Best regards,

Anteja
