writing to POST leds?

I have a POST (Power On Self Test) display card that registers and
displays the POST values on LEDs. I have removed the useless clock speed
LEDs with POST codes instead since in addition to the BIOS, the kernel
etc. writes to them. The address is IO port 80. Here is the dumb
question, since I doubt that the meanings of the values are documented
anywhere, how might I find places where the code references them. As you
might guess, I am not entirely clear on how to write to the LEDs. Is
there any standard way?
