[edk2] 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,
