Uploading Firmware to Prusa I3 type priner

I am well behind the curve on these things - call me a preemie-newbie. In order to load the firmware does the board have ot be connected to all of the pieces like motors
heaters, SD card reader,etc.?
I have a spare melzi 2.0 controller board with a burned out bed heater connection I am trying load. The console shows the bed heater missing and no SD reader then goes into DebugLevel:14and procedes to print "Wait" for a long time (2 hours so far). The board was working OK with the exception of the bed heater but I replaced the board and uploaded the old firmware using raw avrdude commands.

No, you just need to connect the usb cable in order to upload firmware
