I am not sure how I have been lucky enough never to encounter the HP/Compaq booby trap but until today I was so fortunate. Apparently HP Tattoos a number in the bios of their motherboards so that when you try to use the factory recovery, it checks to make sure the stock motherboard is in place. If it is not in place you get the following error:

Your system has detected a configuration error. Please report this error to Customer Care using the phone number found in the Warranty and Support Guide that came with your PC. Unless corrected, this error will prevent your PC from operating properly. Turn off your PC by pressing and holding the Power button. After a few seconds your PC will automatically turn off. (Code Purple)

I mean seriously? HP does not want you to be able to change the motherboard in their PC’s. I am guessing this is some idiots solutions to piracy somehow but in any case I will stop complaining and get to the solution.

It took some searching but I finally found a solution to this problem.

There are a few ways to do this but basically there is a script in the recovery image of the operating system which checks the bios for the correct motherboard code. It is a pretty simple batch script which says if the numbers don’t match return a exit status of 1 and give the code purple error and if it does match give a exit status of 0 and move on to the clean up phase.

I will say that normally you would have to mount the drive on another computer or boot a rescue disk of some sort in order to do this but it turns out that HP was nice enough to give us access to a cmd.exe window even when receiving this error.

1. Once the error box comes up press shift and F-10 to get a command line.

2. Navigate to the following folder.

C:\hp\bin\checkdmi\

3. Enter the following command.

checkdmi.cmd

4. The code looks like this:

if ERRORLEVEL 1 goto mismatch
goto cleanup

REM ------------------------------------------------------------------
REM Found discrepancy in the DMI. Notify the user with the localize
REM message via lg.ini, then shut down the system immediately.
REM ------------------------------------------------------------------
:mismatch
echo - Mismatched DMI - >c:\hp\support\CodePurple.log
echo DMI from Master UUT: >>c:\hp\support\CodePurple.log
type DMIinfo.ini >>c:\hp\support\CodePurple.log
echo ---------------------------------------------- >>c:\hp\support\CodePurple.log
echo DMI from This UUT: >>c:\hp\support\CodePurple.log
type DMIofUUT.ini >>c:\hp\support\CodePurple.log
echo ---------------------------------------------- >>c:\hp\support\CodePurple.log
del DMIinfo.ini DMIofUUT.ini
start /w c:\hp\bin\MsgAction.exe "%title%: %message%"
shutdown.exe /s /t 0
goto end

5. All I did was change the line “if ERRORLEVEL 1 goto mismatch” to “if ERRORLEVEL 1 goto cleanup”

6. Save the file

7. Reboot with the following command.

shutdown -r -t 0

8. Once the system comes back up you should move past the dreaded “code purple” error with no problem.

    However, instead of going to down to where the errorlevel is compared in the code, type “goto cleanup” at the begining of the file and press enter. Then save the file

    Hello scottroybtw,

    No worries. There were some errors in the article because back slashes were not showing up. You might try following the steps again to see if you are able to complete them now that we have corrected the errors in the article. If that doesn’t help then let us know where you are having a problem.

    Thanks.

    Thank you for your patience with us dummies Alex.
    here is the steps I had to take in order to fix my computer:
    at the error box – shift F10
    at the c prompt type: chdir C:\hp\bin\CheckDMI (make sure you put a space after chdir)
    Next type dir
    you will see that there is a file called CheckDMI.cmd
    at the prompt type: rename CheckDmi.cmd CheckDMI
    press enter

    to make sure the file name was changed type dir

    FIXED !

    Thanks for the post and forum. I’ve purchased 2 desktops and 3 Notebooks from HP for me and my wife over the past five years. Each time we’ve “upgraded” it had been in response to a crash that I couldn’t recover (I’m not a computer SME). The techies (GeekSquad, etc.) each time recommended purchasing a new mother board, which in the end was not the best course of action for us since a new computer cost only a few hundred more than the “necessary” upgrade. It wasn’t until today after getting a “code purple” on my desktop that I researched and understood that HP (under a MicroSoft thumb) actually incorporated code (antipiracy) that would disallow modifications or upgrades…not even additional memory!!! And so today I lost a ridiculous amount of work and had to purchase then install (actually re purchase and re install) multiple programs after doing a system restore. During my two hours on the phone with HP tech support I was finally able to get them to understand that all I wanted was a phone number to lodge a formal complaint…I ended up having to spell each letter of each word of each sentence using alpha-numeric designation (gotta love outsourcing). They only continued to quote that my warranty had expired and there were no other numbers for customer service. Of course the “error” has nothing to do with the warranty and HP is required to fix the problem as a result of a lawsuit. I got nowhere. Wow!! HP Customer No-Service (to quote Clark Howard). I wish I’d known years ago that HP had lost a lawsuit over this…I’d have never continued to do business with them. And now I will tell everyone to steer well clear of HP. Five computers in five years and the two we have left are still subject to HP’s hugely successful business model: sell systems that require frequent updates which when installed damage the hardware or negates the operating system forcing the consumer to purchase additional hardware that shuts down the entire system requiring the consumer to purchase a complete new system…rant over.

    Their piracy solutions always punish their customers and they just don’t seem to care!

    I don’t need this “fix” currently but it would be a good thing to know should I ever need to replace my motherboard. Unfortunately it doesn’t seem to be set up the same on all HP computers using Vista. Like some of the previous posts there is no checkdmi folder or checkdmi command file on my computer. I even used two search programs and included system and hidden files and searched the registry.

    It looks like it may be done a different way. There is a precmdline.cmd file that looks like this:

    if exist c:\hp\hpqware\preuser.cmd c:\hp\bin\commands /c c:\hp\hpqware\preuser.cmd
    if exist c:\hp\bin\CheckDMI\CheckDMI.cmd c:\hp\bin\commands /lw:c:\hp\bin\CheckDMI\lg.ini /WW /c c:\hp\bin\CheckDMI\CheckDMI.cmd
    c:\hp\recovery\bin\WAUfix.bat

    I’m not sure how it works but it does check for checkdmi.cmd in the checkdmi folder so I’m guessing that if the preuser.cmd file exists (it doesn’t on my computer) then the commands application creates the checkdmi folder and command file. If anybody figures it out please post it here for everyone. Thanks.

    Thanks for these man! I own a Hp Media center M8200n i love these machine ,but eventually the OS just doesnt start up. Whenever itt happens i run system restore, and when that doesnt help, i just run the original factory format.
    However a year ago one of the ddr2 ram memories failed y i put another one, so i got the code purple thing, i found this post and understood all the hp situation for non piracy non mod of the equipment, but come on i live in central america, how am i susposed to call hp support? through skype? no way.
    So it was difficult for me to navigate to the folder you were specifying, and didnt work on any way, then found that if you hit the “Tab” key you are able to navigate through the file on the system32 folder, so i execute this
    1. on the error message i pressed shift+f10
    2. on the cmd prompt i type after the usual line that appears there “notepad.exe”
    3. on notepad you can use your mouse to navigate like if you are on the windows explorer, the trick is to change the file type on the lower right corner of the open file window, and set it up to “all files”
    4. on the “find” line where the magnification glass appears just type “dmi” so windows can find the checkdmi.cmd archive, select it and open it.
    5. then you’ll find the code thats had been mention above, just changed the lines where the level code is from “1″ to “0″ and the line where saids “goto mistmatch” to “goto clean up”
    And then just like magic, it worked once again like the way i purchase originally.
    I purchase this pc on late 2007 and this is the second time i have to go trough the factory status format.
    Thaks a lot and i hope this can help more people who are unable to navigate trough the command prompt just like me….

    Great, great, great thanks for this information! My 4 year old HP crashed very frequently lately and when I today on top of that also donwloaded a visurs somehow that basically locked out my computer, I thought “what the heck, I will do a factory setting restore” (after backing up most of my data). When getting the “code purple” error after that I kind of regretted that:-( I spent half an hour looking for solutions but all others that I saw where quite complex (=too complex for me). The fix above worked flawlessly. Type edit checkdmi.cmd to get into checkdmi.cmd. The structure of my file was different than the one in the axample but I also only changed
    “if ERRORLEVEL 1 goto mismatch” to “if ERRORLEVEL 1 goto cleanup”

    Computer works like a champ again!

  15. Nick says:

    Thank you for this wonderful guide. Helped me through going past the purple code though when I opened the checkdmi.cmd it appeared different than the parameters above. So I just changed the word mismatch to clean up, “1″ to “0″ then deleted a long parameter that instructs the system to pop up the purple code message though the forgot the actual parameter but it has a part where it says shutdown -r -t 0. Then that does the job.
    To purehate and Narajae, thank you so much. Saves me so much time looking for answers.

    What the Hell can we do about it. I put a HP MB back in my PC. HP said if I used the same chipset, no problems. Now, like someone else said, they have never heard of CODE PURPLE. Support just told me I destroyed my PC. I did what they told me to do. They just told me I lost all of my data. I don’t care about that. Can I get XP back on that hard drive? I bought a new one a while back and was going to upgrade my old one to give to my Son. Anything I can do to get it working again?

    You saved my life too! Unbelievably easy! THANK YOU SO MUCH!

    After hitting shift+F10 to get to the command prompt and navigating to c:\hp\bin\checkdmi\, I copied checkdmi.cmd onto a USB thumb drive, edited the file on another computer, and copied the updated file back onto the system (thus overwriting the original).

    Note that my Windows 7 system had a different script than yours in the checkdmi.cmd file. Mine contained (among others) the following 4 lines:

    :mismatch
    start /w c:\hp\bin\MsgAction.exe “%title%: %message%”
    shutdown.exe /s /t 0
    goto end

    I simply deleted the last three of these lines (leaving the “:mismatch” line in place).

    Worked perfectly, and was so easy to do!

    This worked perfectly! I was rebuilding an HP desktop for a client and I ran into this error. The machine was store bought with no modifications so I am very disappointed with HP’s “anti piracy” checker. Anyway, I did the above but instead of deleting the aforementioned code, I simply REM’ed out the code for the “mismatch” procedure. Typing “REM” before each line tells the computer to skip the line and go past it. So if the computer detected a problem, it simply skipped everything and allowed Windows to continue loading without displaying the error.

    Original code

    :mismatch
    start /w c:\hp\bin\MsgAction.exe “%title%: %message%”
    shutdown.exe /s /t 0
    goto end

    Altered code

    :mismatch
    REM start /w c:\hp\bin\MsgAction.exe “%title%: %message%”
    REM shutdown.exe /s /t 0
    REM goto end
