[MinnowBoard] Minnowboard Max no longer booting to UEFI Shell

[Peter Ogden]

Working with the FTDI cable is very easy.

1. Get the latest Virtual Com Port drivers from the FTDI website:
http://www.ftdichip.com/Drivers/VCP.htm

2. Plug the cable into the minnowobard FTDI header.
http://www.elinux.org/Minnowboard:MinnowMax#6-Wire_Serial_Console

3. Look in the windows device manager and find the COM# for the FTDI cable.

4. Use a serial terminal emulator like Putty.exe with these settings:
Serial port = COM#
Speed = 115200
Data bits = 8
Stop bits = 1
Parity = None
Flow Control = None

5. Power up the minnowboard with no boot device and you should see the EFI
shell show up in the terminal.  Its an exact mirror of the EFI shell you
see with a monitor connected with HDMI.

6. Flash the new firmware using normal EFI commands.  There's a video on
this page:
