user15949: I am trying to make the following board work with Raspberry Pi.
Board Name: L293D Motor Drive Shield Expansion Board for Arduino Mega Raspberry Pi

All I need to know is which pins do the following:

Enable the motor
Disable the motor
Rotate forward
Rotate backward

More information about the board:

Can someone please help me find this information?

The following pins are in use only if the DC/Stepper noted is in use:

Digital pin 11: DC Motor #1 / Stepper #1 (activation/speed control)
Digital pin 3: DC Motor #2 / Stepper #1 (activation/speed control)
Digital pin 5: DC Motor #3 / Stepper #2 (activation/speed control)
Digital pin 6: DC Motor #4 / Stepper #2 (activation/speed control)

The following pins are in use if any DC/steppers are used

Digital pin 4, 7, 8 and 12 are used to drive the DC/Stepper motors via the 74HC595 serial-to-parallel latch

The following pins are used only if that particular servo is in use:

Digitals pin 9: Servo #1 control
Digital pin 10: Servo #2 control
