I just got done disassembling an 8100 and resetting the bios OK. But now the dang thing has a password for the hard drive!!! Does anyone know how to crack this one? I've removed the drive and tried slaving it on a regular desktop pc but it's still inaccessible. If I just buy a new hard drive, will it work ok?

Here is the only thing i can think of that will help you, you take the tower, yes the black thing with the blinking lights the cd drives and the wires coming out of it that says DELL on the front, throw it in a dumpster 2 towns over, then goto http://www.tigerdirect.com and buy yourself a real computer.

Pete: if you really don't care about the data on the hard drive (i see you're willing to just replace the HD with a new one) then why don't you try formatting it? you could probably do it set as slave. :-/

as for the bios thing, i did a simple google search and found something that might help some: http://labmice.techtarget.com/articles/BIOS_hack.htm

the answer can usually be found with some good ol' googling.

Here's a link w/all the info about the location of the chips you seek and why the hd password can't be cracked. (I have a number of them and am gonna hate to toss 'em!) I wonder if changing the pcb would work.........?

If you cannot access the machine after if has been powered up, it is still possible to get past the BIOS password. The BIOS password is stored in CMOS memory that is maintained while the PC is powered off by a small battery, which is attached to the motherboard. If you remove this battery, all CMOS information (including the BIOS password) will be lost. You will need to re-enter the correct CMOS setup information to use the machine. The machines owner or user will most likely be alarmed when it is discovered that the BIOS password has been deleted.

On some motherboards, the battery is soldered to the motherboard, making it difficult to remove. If this is the case, you have another alternative. Somewhere on the motherboard you should find a jumper that will clear the BIOS password. If you have the motherboard documentation, you will know where that jumper is. If not, the jumper may be labeled on the motherboard. If you are not fortunate enough for either of these to be the case, you may be able to guess which jumper is the correct jumper. This jumper is usually standing alone near the battery. If you cannot locate this jumper, you might short both of the points where the battery connects to the motherboard. I am aware that this is a notebook and not all BIOS passwords can be cleared by just resetting the CMOS. You also may not feel that comfortable opening it up a notebook due to the fact parts are much smaller.

Windows XP/2000 Password:

If you are running Windows XP/2000, I would suggest downloading a program known as CIA Commander. Its a simple DOS based program which will do everything you want it to do to clear a Windows password. I would document on how to use it but documentation is included with the program itself.

Dell Inspiron 7000 BIOS password

I also have one of those that a well-meaning "helper"
password-protected the BIOS on, and now we can't get in...

Was anyone able to help you?

Appreciate hearing from you on this.

Thanks

(this notenook uses the 24C164 chip instead of the 24C02
so shorting the terminals won't erase the password, or so I've
been told...)

I am currently in the same position with a DELL inspiron 7000. I have today removed the 24C164 chip and erased it completely. Refitted it and booted the PC to find it is still asking for the bios password??

Starting to think this is not where the password is stored. Instead it may just be the DELL unique number.

Any ideas appreciated anyone.

I have now managed to remove the bios password from the DELL inspiron 7000.

I wanted to post this as it was difficult to find any decent information on this procedure. I hope this is of help to someone.

Procedure used (not the only one I believe):

The laptop has to be taken completely to pieces. I mean everything as the 24C164 device is on the underside of the main board. It is just above the PLCC bios chip.

I removed this device from the board and luckily have access to an IC programmer. The device was filled with FF's which effectively blanks the device.

But the next step is more important and is where I went wrong the first time. You have to then clear the CMOS. On the same board is a small PCB mounted cell. Remove the +ve leg and leave for a short while and then reconnect it.

Put everything back together and you should be away. It worked for me anyway.
