      I happened to find them at this site for a good price.

      http://www.buydvb.net/pm2c-pcie-mini-pcie-adapter_p17.html

      For 1 it's $24.99 + 4.42 = $29.41

      and for 2 it's $49.98 + 6.71 = $56.69  ( use promo code 9128c08514 for $5 off $50)

      I got the customer service lady to change it for me. I will let you know if they work well in 2 weeks. I grabbed 2 of them.

      This is for anyone who might be interested in trying this.

        Interesting solution.
        Wouldn't the PCIe card stick out the bottom of your notebook though? Useful for testing I guess.

          Yes, but the pfsense router will be sitting in the back room on a shelf. I think I am going to make a box out of 1/4 MDF or some cardboard.

            Why not just use a pcmcia network card? Years ago I ran pFsense on a Pentium III notebook and a d-link 10/100 card.

              Are there any laptops that have both Mini PCIe and PCMCIA?

              I would think anything with with m-PCIe would be express card or nothing.

                Intel NICs are far superior and who still uses non gigabit these days?

                  Depends on your situation.
                  If you are re-using older hardware as a home gateway then you almost certainly don't need gigabit (unless you're living in Korea or Sweden).

                  My loadbalanced WAN connections can provide a theoretical maximum of 70Mb/s so there is no need for gigabit ethernet on my box. In fact it does have gigabit interfaces but they are all running at 100Mb/s as that's what's connected to them.

                    so I ended up doing this on a Thinkpad T60 and it works great. I have a couple questions though.

                    How do I get the log from pfsesne booting up? I would like to see that to see if everything is working correctly. When I installed pfsense on Windows 7 this computer was idling at 16W and it is at 23W now with pfsense.

                    I read somewhere that the Core 2 Duo CPUs sometimes only enable speedstep on one core? How can I fix this? Thanks!

                      pfSense will not use any power saving features by default, it doesn't expect to be running on a laptop!
                      Have you enabled powerd?
                      You will probably have to switch the timecounter to enable powerd.

                      16W seems pretty good, 21W doesn't seem too bad.  ;)

                        pfSense doesn't enable Intel Speedstep (EIST) by default.  Try this:

                        Go to System -> Advanced -> Miscellaneous -> Enable PowerD

                        Go to Diagnostics -> Edit FIle -> Create /boot/loader.conf.local
                        Insert:

                        hint.p4tcc.0.disabled=1
hint.acpi_throttle.0.disabled=1
est_load="YES"

                        Reboot for effect.

                          Thank you, it would be nice to get it to that 16W though if possible. :) I tested my other gear as well:

                          Dell PowerConnect 2816 Switch - 10W
                          D-Link DIR-655 as AP - 7W

                          , so 16W is pretty good for sure.

                          pfSense doesn't enable Intel Speedstep (EIST) by default.  Try this:

                          Go to System -> Advanced -> Miscellaneous -> Enable PowerD

                          Go to Diagnostics -> Edit FIle -> Create /boot/loader.conf.local
                          Insert:
                          Code:

                          hint.p4tcc.0.disabled=1
                          hint.acpi_throttle.0.disabled=1
                          est_load="YES"

                          I assume this is right?

                          "The powerd utility monitors the system state and sets various power control options accordingly. It offers three modes (maximum, minimum, and adaptive) that can be individually selected while on AC power or batteries. The modes maximum, minimum, and adaptive may be abbreviated max, min, adp. Maximum mode chooses the highest performance values. Minimum mode selects the lowest performance values to get the most power savings. Adaptive mode attempts to strike a balance by degrading performance when the system appears idle and increasing it when the system is busy. It offers a good balance between a small performance loss for greatly increased power savings. The default mode for pfSense is adaptive."

                          • so how/where do I enable the different modes at? I just did the above and restarted. I am at ~20W now and the fan is still going pretty fast, which indicates to me it's not working 100% yet. Thanks for the help!

                            Hmm, ok.
                            You need to check the boot log for powerd messages. It looks like it's not loading correctly. The est driver is compiled into the kernel so there's no need to load it (doesn't hurt though).
                            If it's running correctly you should see on the dashboard next to cpu type a maximum and current frequency.
                            Alternatively you can run powerd -v at the console to see what frequency it's running at.

                            If it isn't running you may have to change the kernel timecounter. See: http://forum.pfsense.org/index.php/topic,20095.msg195755/topicseen.html#msg195755

                              It looks right.  To verify, go to Diagnostics -> Command Prompt.  Type:
                              sysctl dev.cpu

                              The output of "dev.cpu.0.freq_levels" will list the frequency steps available.  Here's an example output of my setup (Intel Core Solo T1350; 133MHz FSB).  Your Core 2 Duo will have dev.cpu.1.* output as well because of the 2nd core.

                              $ sysctl dev.cpu
dev.cpu.0.%desc: ACPI CPU
dev.cpu.0.%driver: cpu
dev.cpu.0.%location: handle=\_PR_.CPU0
dev.cpu.0.%pnpinfo: _HID=none _UID=0
dev.cpu.0.%parent: acpi0
dev.cpu.0.freq: 800
dev.cpu.0.freq_levels: 1867/88000 1600/73000 1333/59000 1067/48000 800/37000
dev.cpu.0.cx_supported: C1/0
dev.cpu.0.cx_lowest: C1
dev.cpu.0.cx_usage: 100.00% last 5000us

                              You can see that the steps are always a multiple of the FSB (133MHz aka 533MHz).  In my case, it's 266MHz (2 x 133MHz) steps.

                              With PowerD but without disabling P4TCC, you will see many more steps in 100MHz steps.

                              For the T60 with a Merom Core 2 Duo, the lowest frequency will be 6 x 166MHz(FSB) = 1GHz.
                              If you have a Core Duo or Core Solo with 133MHz FSB instead, the lowest is 6 x 133 = 800MHz (Same as mine).

                              On the topic of the fan, I don't think there are platform specific ACPI drivers loaded for controlling the onboard fan.  You'll need to enter BIOS (hit the Thinkvantage button on boot) and set the Processor Cooling Policy to Active rather than Passive.  The hardware should handle things on their own from there.

                                On the topic of the fan, I don't think there are platform specific ACPI drivers loaded for controlling the onboard fan.  You'll need to enter BIOS (hit the Thinkvantage button on boot) and set the Processor Cooling Policy to Active rather than Passive.  The hardware should handle things on their own from there.

                                I will have to see what options are in the BIOS.</stmicroelectronics></samsung></hl-dt-stcd-rw></intel></intel></intel></intel></intel></intel></intel></intel></intel></intel></enhanced></enhanced></generic></system></isa></ac></acpi></ps></at></keyboard></at></thermal></thermal></serial></ata></intel></ata></intel></isa></pci-isa></cardbus></ti1510></acpi></acpi></intel></intel></intel></intel></intel></intel></intel></intel></intel></intel></acpi></acpi></acpi></acpi></intel(r)></acpi></acpi></intel(r)></acpi></acpi></multimedia,></vga-compatible></acpi></acpi></acpi></acpi></sleep></control></high></acpi></acpi></embedded></lenovo></software></version></lenovo></lahf></syscall,nx,lm></sse3,dtes64,mon,ds_cpl,vmx,est,tm2,ssse3,cx16,xtpr,pdcm></fpu,vme,de,pse,tsc,msr,pae,mce,cx8,apic,sep,mtrr,pge,mca,cmov,pat,pse36,clflush,dts,acpi,mmx,fxsr,sse,sse2,ss,htt,tm,pbe>

                                  Just in terms of reducing the fan noise it is almost certainly worth the effort to clean the fan/heatsink assembly in an old laptop. Even if it looks relatively dust free from the outside.
                                  I recently looked at a friends laptop that was running very hot and eventually turned itself off. After blowing out the heatsink with compressed air and remounting the assembly to the cpu with decent quality heatsink compound the idle temperature went from 63°C to 40°C. The fan is barely audible at this temperature.
                                  On that Sony Vaio it was relatively easy (surprisingly so) to access the CPU, I realise that most laptops are a PITA to disassemble.

                                    I actually did clean it out and changed the paste when I put the T5500 in it to replace the T2400 it had in it.

                                    Thank you for all the help.  :)
