The "extradac" is a connector that provides 8 digital output bits. If you want to use it as a DAC, the extradac parameter creates a single HAL pin to pass an 8-bit integer. If you instead give the extradout parameter sets up 8 output pins so you can address each output bit separately. In both cases, the numeric value does nothing, it is there because HAL requires a value for every parameter.
Don's command did not specify the parallel port address, and let it default to 0x378. If that is not the correct address, then he would have to specify something like : loadrt hal_ppmc port_addr="0xd800" extradac=0x00 where 0xd800 is the address of the parallel port.
