5- Install process for winboard

5.1- Download and install winboard on your system. You will probably install it at folder: C:\Program files\WinBoard (C:\Arquivos de programas\WinBoard)

5.2- Create the 2 new folder (crie as 2 novas pastas) engines and (e) xadrecov57:

C:\Program files\WinBoard\engines\xadrecov57 (C:\Arquivos de programas\WinBoard\engines\xadrecov57

5.3- unzip the file into this folder (descompacte o arquivo nesta pasta): xadreco.tar.gz

5.4- Follow 5.4.1 for a easy new installation. Follow 5.4.2 if you have others engines working with winboard already. (Siga 5.4.1 para uma instalação nova e simples. Siga 5.4.2 se vc já tem outras engines instaladas com o winboard).

5.4.1- If you have a fresh winboard install, you can just copy the file C:\Program files\WinBoard\engines\xadrecov57\winboard.ini to the winboard folder: C:\Program files\WinBoard\

(Se sua instalação do winboard é nova, basta copiar o arquivo winboard.ini que acompanha o xadreco para a pasta do winboard)

5.4.2- If you have already set up another engines to your winboard.ini, then just open your winboard.ini and add the lines:

winboard.exe -cp -fcp "engines\xadrecov57\xadreco.exe" -fd "engines\xadrecov57" to your /firstChessProgramNames= group; and

winboard.exe -cp -scp "engines\xadrecov57\xadreco.exe" -sd "engines\xadrecov57" /secondChessProgramNames= group;

Notice that this version do not need the parameter "xboard" to work.

(Se você já tem algumas outras engines configuradas no seu winboard.ini, então adicione as linhas:

winboard.exe -cp -fcp "engines\xadrecov57\xadreco.exe" -fd "engines\xadrecov57" no grupo /firstChessProgramNames=

e

winboard.exe -cp -scp "engines\xadrecov57\xadreco.exe" -sd "engines\xadrecov57" no grupo /secondChessProgramNames=

Repare que a partir desta versão não é mais necessário o parâmetro "xboard" para o seu funcionamento.
