Rajesh,
I think what you gave here is the windows installation key
What is needed is the computer model number.I have successfully unlocked a bios by connecting pins on the (db25) parallel connector and booting.It all depend of model.

Hi,
well... maybe yes... I don't know, it's the software that change that details in unbelivable way.

Anyway, I like her real face more than drawing though it's not so beautiful girl at the end.

Kind regards,

Hi Rajesh,

Is this the BIOS password or the Windows password you've forgotten?

Or it's some ehm... Kremlin pwd ???

that's the key... depends what there is... suppose you have a ...ops... uncommon bootloader... ok... you reset the bios and so remove the password startup check then... you enter bootloader pwd check and that's not so easy in this case...

Uhm... but sure, I think you know how to hijack that kind of gizmoes!

I will run e.g. some ehm... "customized" os and play a bit trying to identify the actual record of system os bootloader... then you could ops... have the pwd problem at os screen level if there is... so other work and other pain... you need some smart things to see it on other ehm... point of views : DO YOU UNDERSTAND WHAT I SAY ?

But... the question IS ... why all that pain ? for what ?

If really interesting stuff one can steal with no pain there with uncommon strategies but why so worried in restoring an hanged system ? Why don't formatting and load everything brand-new from dvds ???

MUST ASK Rajesh I know...

Kind regards,
Max

The easiest way is to open the back of the laptop and remove the CMOS battery, and leave it out for several minutes. When you put it back, the BIOS will have been reset.

If this is a more modern laptop, it may have a security chip, and removing the battery will not work. Depending on the chip, you can short together certain pins, and that will reset the BIOS.

What is the make and model of the laptop?

yes right... but I think some people could be "scared" of shorting pcb tracks during startup... not me , of course!

I made similar "experiments" on some Dell lapthings

With interesting results... like some smoke here and there...

Hi Rajesh,
my friend I suggest , if you really need the informations trapped in that laptop, to find a good , trusted... ehm... "hacker"

I KNOW trusted hacker maybe is not self-explaining ... I mean you need someone that can read the whole Dell thing content without any Admin pwd or something...

I think you may ask people from some e.g. local unix/linux club maybe... or similar folks ( you may recognize them cause often they wear t-shirts with labels like "fu** the system" etc... )

I'm sure you'll find a couple of guys ready to hack-down any data there... for free!

BUT , do not contact these guys by email... better buy a ticket for the next linux-day and wear similar t-shirts there... just to seem like one of them...

Kind regards,
Max

bios

whos the ic wiil be reset

[Qiaozhi]

There is a program here that will calculate the master BIOS password for Dell Latitudes from the Service Tag number -> http://www.users.globalnet.co.uk/~sk...s/latitude.exe

You need to open a DOS window (obviously on a different machine) and enter "latitude 12345", where you replace 12345 with your service tag number.

I also read somewhere that you can use a backdoor BIOS password. Trying entering "Dell". This is claimed to work for some Dell machines.

hi qiaozhi where sould be save this program

[Götz von Berlichingen]

About the "latitude.exe", you can save it wherever you want, but you need to run it from the command line.
It wants a 5 letter service tag number - yours looks longer than this.


A good Hardware Hacker can solve the Password Problem like this :
