      Agreed, strange output.
      I certainly does help. It looks like you've got ICH2 so that's a different datasheet for starters.
      If you do a:

      pciconf -lb

      You should see the PCI device and vendor IDs to confirm the chip.
      Look for chip=0x24408086 or chip=0x244C8086. That's the LPC-PCI brigbe used to configure the GPIOs.
      That command should give you the base pci address and from that you can read the gpio base address and then test the gpios. However on my box it doesn't!  :(

        Luckily, pciconf -lb does work here.

        0x244C8086 shows up as:

        0x244C8086 isn't in the output.

        However, I don't know how to interpret 0xff00 as the base.
        Running ./readio gives me the following:

        
[2.0-BETA5][admin@firebox1.domain]/etc/rc.d(5): ./readio 0xff00
Reading ff00 :0

          2440 is the ICH2 chip,82801BA, 244C is ICH2-M, 82801BAM. You have the former.
          Unfortunately your output is like mine. The base address we need is that of the isab0 device, not listed.
          Still this is all interesting stuff!  :D

            And there I was thinking it did work for me!

            So, is there another way of finding out what the base address for lsab0 is?

            And I agree that this is all very interesting, though it does go slightly over my head.
            Still, it must be said that you are good at explaining what I need to to and what to expect!

              I have to say I'm learning as I go here.
              There must be another way since it's an integral part of the os. I have a feeling it's probably passed to the os by the bios. Certainly the bios code sets up the chipset initially so if it moved the gpiobase thats where it would be stored.
              Intel provide a helpful application note for doing just this. Here.
              They explain how it's all setup and how the registers relate to one another. They even provide example code for finding the gpiobase and the LPC base and it's written for FreeBSD. Unfortunately it's only sample functions and not something that could be compiled.  :(
              I don't really want to start messing about trying to write a program to do this. I sure there's FreeBSD package that can do this already I just don't know what it is.

                Edit: Don't do this! Perhaps it makes interesting reading for someone. See my post a few below here after Wallabybob pointed out my failure to understand pciconf.  ::)

                Here's something that seems to work, if you're feeling brave!  :P I spent ages trying to compile a very simple program but gave up after more compile errors than I could count. Anyway the basic functionality is included in the pciutils package. First install the package:

                
/etc/rc.conf_mount_rw

pkg_add -r pciutils

/etc/rc.conf_mount_ro

rehash

                This is a port of the Linux lspci utility with some extra bits.
                Fire it up and see what you have:

                This is my Xe box. You can see the ICH LPC bridge listed has PCI address 00:1f.0 (obviously change this to your address).
                So now we can get lspci to spit out the configuration data. This function comes with a danger warning but works fine here:

                [2.0-BETA5][root@pfSense.localdomain]/root(35): lspci -s 00:1f.0 -xxx

f0: 01 c0 d1 fe 00 00 00 00 80 0f 04 00 00 00 00 00

                So now we have the important part of the configuration table. Looking at the datasheet for the ICH6 the GPIO base address is stored in registers 0x48-0x4b. You have to read it in reverse: 00 00 04 81. i.e 0x481 Except that reading the datasheet more closely we see that "bit 0 is hardwired to 1 to indicate I/O space" for some reason.  ::) So the actual address is 0x480. Which we know to be true.

                This procedure should work fine for you except that in the ICH2 the gpio base address is at 0x58-5B instead.

                Steve

                  The FreeBSD utility pciconf can also be used to get this information. There is a man page at http://www.freebsd.org/cgi/man.cgi?query=pciconf&apropos=0&sektion=0&manpath=FreeBSD+8.1-RELEASE&format=html

                    Doh!  :-[
                    It was like three in the morning by the time I wrote that.

                    The same result can be had with:

                    [2.0-BETA5][root@pfSense.localdomain]/root(10): pciconf -r pci0:0:31:0: 0x48
                    00000481

                    On the X-core box with the ICH2 you need to look at 0x58 but the LPC device is in the same place so:

                    
pciconf -r pci0:0:31:0: 0x58

                      Progress! That is to say, the command gives me a response on my firebox.
                      The response is as follows:

                      
[2.0-BETA5][admin@firebox1.domain]/root(1): pciconf -r pci0:0:31:0: 0x58

                      I'm not sure what this means though!
                      What is the next step?

                        Aha! That's disappointingly similar to 480, open to confusion but it looks as though the GPIObase address is 0x4080.
                        The next setp is to re-try the instructions from here but using 0x4080 in place of 0x480.
                        Hopefully you should get something other than all ff or 0.

                          Indeed, the numbers are so alike that I first thought I had gotten the same response as you did.

                          And now, with your help, readio has given me an answer other than ff!

                            Not a problem, they should be.
                            So:

                            Experimental findings of ICH2 IO space;  

0x4080-0x4083 Set pins as gpio or native fuctions. 1=gpio
Default 1a003180				                0001 1010 0000 0000
Found  1a203180      						0001 1010 0010 0000 

0x4084-0x4087 Set gpios as input or output. 1=Input
Default	0000ffff
Found	0000ffff	bit 1 is input. Possible outputs are 	0000 0000 0000 0000 1111 1111 1111 1111 

								   1 1 1    1  (set as gpio & set as output)

0x408c-0x408f GPIO Levels
Default	1f1f0000											
Found	09bf0000				   	        0000 1001 1011 1111

                            Hmm, doesn't really line up properly on the forum but.. Edit: Better

                            Only four pins are both enabled as GPIO and set as ouput and only two of those are set to 1. So try seting either of those to 0.

                            ./writeio 0x408f 0x01

                            Return it to it's original value after or things get confusing! Or:

                            ./writeio 0x408e 0x9f

                            One of those should switch off the red led.

                            Once we know that we can work on green and flashing!

                              Thanks, I've been meaning to try this.
                              However, when you write 'Return it to it's original value after or things get confusing!', how do I know what the original value was?
                              0x408e gave me a response of bf, so would that be 0xbf?
                              Or am I being nonsensical?

                                Yes, bf is 0xbf. I never really expected anyone else to be using the program so didn't spend much time sanitising the output, sorry.  :P  (in fact I don't think it matters if you include the 0x or not)
                                When you change 408e from 0xBF to 0x9F what you are actually doing is changing only 1 bit (B=1011 and 9=1001). I say to change it back since if you change more than one thing at a time it's hard to know what change had what effect.
                                The fact is that we don't know what, if anything, the other gpios are connected to. It's better to return them to their original state. On the boxes I have here none of the random number setting I have done had any ill effects and it all gets reset by the bios at boot so don't worry.
                                Good luck!

                                  After trying both ./writeio 0x408f 0x01 and ./writeio 0x408e 0x9f, I found the following:
                                  The first command (0x01) makes the red led blink red / off (looks like it blinks synchronised to re0, but I'm not sure).
                                  The second command (0x9f) does nothing (seemingly).

                                  Afterwards, I reset 0x0408f to 0x09 and 0x408e to 0xbf.

                                    Hmmm, interesting. Well it's something at least. It proves that the led is driven by the gpios i some way.
                                    So it doesn't blink regularly, like once a second?

                                    Anyway it seems that 0x408f bit 3 is red on.
                                    To find green leave red off (or blink in this case) and try turning on bits 1 or 4 i.e.

                                    ./writeio 0x408f 0x11 or 0x03.

                                    Normally the blinking action is set by the blink register which for you should be at 0x409b, to correspond with the ouputs at 0x408f. Try reading 0x409b, by default it is 00.

                                      I've tried both settings.

                                      ./writeio 0x408f 0x11 turns the led green and blinks at fast but irregular intervals.
                                      ./writeio 0x408f 0x03 does the same, but turns the led back to red.

                                      I've reset to 0x11 now, so at least the arm led is green!
                                      This is awesome.

                                      Edit: actually, the blinking is regular. About four blinks per second.

                                        Hmm, even more interesting.
                                        So 0x408f set to 03 is the same as 01 yes?
                                        The built in blink function is definitely 1Hz so if it's blinking at around 4Hz then something else is doing it. Still worth checking the blink registers at 0x409A and 0x409B.
                                        It's likely only two pins actually do anything giving only 4 possible states. It appears to be 0x408F bits 3 and 4. We have tried:
                                        01 which is default, solid red
                                        00 red flashing
                                        10 green flashing
                                        11 haven't tried that yet.

                                        Try ./writeio 0x408f 19

                                        As I said there are four possible gpio pins so 16 possible states. Since there is some confusion I think we may just have to work through them.

                                          Good guess!  ./writeio 0x408f 19 turns the led green without blinking.

                                          Edit: Seeing as you now know how to turn the led green on both the x peak and x core devices, perhaps someone can help you with building a package for everyone using a flavor of the firebox?

                                            That's the long term plan. Hopefully we can also include the lcd driver so we can have a single package for Firebox users that doesn't get broken every time you update.

                                            It seems like we're missing something here though. The control is very different to the other two boxes.
                                            Can you tell me what the out outs of these are:

                                            ./readio 0x409a
                                            ./readio 0x409b

                                            Do you have bios access to your box? You can set the initial led status in the bios on the X-core. I can't remember what you could set it to but it was a load of different settings. We should be able to get, at least, all of those.

                                            Anyway it seems like we are mostly victorious!  ;D
