    Well I'm using WinRAR from that quoted link
    Try installing that. Yes it should be 33K

    I know that.
    I was having a useless conversation (as I had clearly stated) on HDD Password only
    And I stated that no one posting here has that issue. I was trying to inform hddcrash69 that all his links wouldn't work as well !
    ie We are not discussing HDD passwords in this thread (wouldn't that be nice and easy ;) ) We are discussing passwords set in Bios.

    So hpgl, sorry you hadn't realized that! You can run simple code to remove a HDD password didn't you know that !?

    But for the rest of everyone here, obviously the conversation I was having with hddcrash69, has zero to do with anyone else
    For all users wanting this valuable information (Bios passwords - however you label it) look here: https://www.techspot.com/vb/post610782-4.html

    Where's your guide hpgl ? Oh yeah you don't know enough to post one
    So maybe I just could know a little more than you technically ;) (I'd say most likely)

    Here's the part you missed hpgl, listen up
    Are you suggesting hpgl that a standard locked password in any Desktop or laptop HARD DRIVE can't be unlocked freely? How absurd! You may need to learn up a bit.

    So back to the thread, the other 99% do require specialized help, and obviously me and about 1 other here (Obi) are the only ones providing this free help. All I see you do is help users (edit: usually 1 user every 3 months) that may or may not even be legitimate, try helping a few members that do actually require your help. I'm sure we'll wait a looong time for that hey? Prove me wrong fool, prove me wrong. Obviously you can't.

    Edit: I've said it before and I'll say it again
    I find enjoyment in putting spammers in their place (you know debating stupid things). I have never met any salesman that knows more than me technically (how strange hey) And I always win in the end, and they are made the fool.

    I help members freely here. But I debate (and win) against spammers. Generally they are a joke; although they do help me quote useful information I have to genuine needy individuals. I will continue every day on this. And have done so for a long time already. Spammers have little to gain here, bring them on. Because this is my home

    remove HDD password is always possible if you know exact password. Such case is trivial.
    No guide from me, I'm too lazy to do it, but I will be very grateful if you do it for all us.
    Desktop BIOS usually doesnt support HDD passwords by ATA-3 standard so there no problem. Laptops HDD much harder, do you know free tools for that?
    I agree, 95% passworded laptop have power-on password only, and few percents have HDD password. And better to purchase new HDD instead unlocking old one.
    Are you blamed me for infrequent help? :)
    Are you wait when I will start to advertize something commercial to be banned?
    No, it my will when I will post here and what I post, until it concern the topic.
    Next message I will post about Dells BIOS quality negligence for years.

    dell bugs investigation

    Why sometimes master password doesnt work: bug4, bugA95B
    And why Dell doesnt fixed it so far or fixed after years. Why Dell didnt change password system at all, as many merchants trades master passwords?

    some DELL models have "bugA95B", in particular Inspiron 1525 bios version below A16.
    BIOS claims -595B tag but as EC firmware have A95B algorithm, the master password must be calculated as A95B tag.

    Dell have "bug4" in the algorithm of checking master password:
    1. read service tag from EC
    2. send data to EC for dellhash1
    3. receive from EC dellhash1 value
    4. calculate dellhash2
    5. send to EC raw data from dellhash2 value
    6. ask EC to type in password and compare with master password calculated from raw data from dellhash2
    7. EC return success or fail
    The bug in the EC firmware in checking first byte of raw data of master password, if it zero - no master password,
    But first byte may be legitemately zero in every 7th password beginning from '4'
    Bug can be easily fixed by checking all 8 bytes for zero.
    Some models like D600 doesnt have this bug but many other still have it.

    You know that I was just getting you to post don't you ;)

    Thanks for your help so far :grinthumb
    And with that, he's gone offline again :( Oh well

    Wow keo80, it took 3mins for you to confirm that the password worked
    From: hpgl post
    Then you viewing it
    Then you trying it
    Then you confirming all is ok
    Then replying to hpgl

    It seems really lightening fast, nearly too quick to be true even ;)
    I'd even go as far as saying not humanly possible :(
    Oh well hpgl you haven't passed this quarter yet !

    OK, guys, you both know a whole bunch about Dells, which is very impressive. I wish someone knew that much about hps, especially the vt6200, lol. Anyway, I am still trying to come across someone who knows the secret behind mine, but I am very impressed with your vast knowledge of the others.

    Kimsland, if you are asking me if I tried the attachment, I have. At least all of it that pertained to my hp. I haven't seen any jumpers like the latitudes jboot, and removing the batts and let it drain did nothing either. It still just does the password prompt, although occasionally, it shows the option of F10, but I hit it, and it still went to password. I'm scratchin my head on this one.

    I downloaded the oldpass.zip, and it kept coming up currupted
  17. kimsland

    kimsland Ex-TechSpotter Posts: 14,524

    Thanks I confirmed with 3 users that it does unzip !
    So therefore you haven't tried it then ?

    Which is it ? Tried the generator, or not tried ?

    Anyway, you may need to try downloading it on another computer

    Here it is again: https://www.techspot.com/vb/post610782-4.html


    By the way, there are 3 generators in that attachment

    And there's also the D35B Dell password generator too in that thread too for any older model Dell computers
    Actually that post should be the first point of reading for all Mobile password requests
    Thankfully I have confirmed all working, well.

    It is just not going to work for me on this computer, I have saved it, tried to open it, and everytime it says file is invalid or currupt. I don't know what the deal is.

    dell latitude d830 bios password problem

    hello guys, I've also a dell latitude d830 and his bios has been password protected. how can I bypass that? Is it possible to "shortcut" his bios chip with the paperclip method? or do I need a masterpassword via it's servicetag number?

    jncaudio TS Rookie

    OK, Kimsland, I had to get winrar to open it, but I got it. Now, how do I use it, exactly?
  22. kimsland

    kimsland Ex-TechSpotter Posts: 14,524

    I also put a ReadMe.txt file in there as well, to avoid these questions
    If you do not know how to copy and paste and how to run a DOS command you may need help from anyone there who can help. ie These basic Windows functions I won't discuss :rolleyes:

    But at least we have learned that you haven't actually tried any of the 3 generators yet. In that Zip file
  23. jncaudio

    jncaudio TS Rookie

    well, I go to the command prompt, or even run, and it will come up for a split second, and then it's gone. except for the unlock 6, but it ask which scan I want to run. I'm not sure where to go from there. I am not trying your patience, I am just not familiar to password retrieval. Please bare with me.
  24. kimsland

    kimsland Ex-TechSpotter Posts: 14,524

    I'm sorry the commands are just too basic for me to explain
    You must be very limited in computer knowledge. Just follow the ReadMe.txt file
    If you have trouble, as I stated, then you may need to learn basic Windows commands including Start->Run-> CMD and the other info supplied in the text document:

    Type in-> hdd_pw 12345 0 (where 12345 is actually the password error code)
    Then Press 2 (Upper Case ASCII Code) (you will see this)

    This area of Windows and how to use and understand it, is beyond (or below rather) the reason for this thread. Maybe go ask any teenager to help, it's very basic


    I'm nearly positive that you will say "it" did not work
    Well the 3 Generators give about 10 to 15 passwords to try, but as I said no doubt none will work for you !
    Anyway, thankfully seeming there was no where else to get all 3 from the web that I could presently find, at least they exist here at TechSpot. Pretty sure a lot of members will be reading that thread (ie H E R E) So that's good at least ;) As others have already stated that the options in that thread have helped them :) TechSpot forums, are free help only

    jncaudio TS Rookie

    I do apologize for sounding as if I am clueless, but that is because I do not have an Error code, or hash code. If I can find that, I can further my search. I am not asking for the password just yet, this is the first laptop I have come across that doesn't shoot a hash at you. That was my problem. I think I could rub the 2 brain cells I've been living on together and figure it out from there, I am not an *****. I am sorry to have given that impression.
