I havea dell x200 and it is locked with an admin password. I have down loaded the bios but I have no idea of the adress in which the password is kept. Does anyone know it. Aso I have been informed that the cmos chip is a u525.And I can not find it. Where would this chip be located?
Last and not least , can this cmos chip be inline programable just like an ibm.(I don't remove the cmos in a ibm to reprogram it to remove crc errors) Any help would be great

Thank you

I would also suggest you read the first post by Julio, referring to the very informative "Previous One"

Dell Info:

anyone can help me with the hdd password the #XJ20P473023-595B

I would highly recommend that All users refer to this Previous Thread
It is extremely informative, and will answer many questions, you may have.

An update on my issue. Removed keyboard pulled the cmos batt. change boot to cd rom us the dstcd cleared the service tag and that deleted the password in the setup menu. Thanks for no help.

Actually you have received a lot of help

And specifically, the dst boot proceedure (you know a couple of posts up, posted by me) !

Very strange that you would say this, when I specifically stated how to remove Dell passwords. And you followed that proceedure exactly

Members like you (ungrateful) are very difficult to please

I have a problem with Omnibook Xe3 about Bios Password and the Hash Code is 03530

Thank you in advance

Thank you for your responce, however I have read all the posts on this board and still cannot find the location of the eeprom chip on a dell x200 motherboard.I have also checked vertualy every site and still no indcation of were the chip is. I have also come across a lot of sites that will sell the info for $20
I could sure use some help.

Hi grc1

I'm on it (still searching, but not exactly positive...yet)

My understanding is it is under the PCMCIA cage or black plastic tape
So you might want to check.

Also the $20 option you found is for info ony (ie a PDF that I already have)
No mention of X200 or X300 in there

Please let me know about under the tape

I now have the x200 completly striped and I still can't find the proper eeprom chip I have found a 93c86 chip but I don"t believe thats it. Also I found a referance on the pcb board of a u252 placment and a chip labled A20RC But I don't believe thats it either. I have kinda run out of places to look. Right now I have turned this in to a family " where is Waldo" Any ideas?

Datasheets, they're across the net freely distributable

ie:
http://www.futurlec.com/Memory/93C86.shtml

I think <member now removed-from TechSpot> is accidently telling us, that the chip is 93C86

But he did help me locate:
Universal Programmer Analyser-UPA 2.3 Lite
http://www.elrasoft.eu/upa2lite.zip

I just need to learn how to use it properly
It also has pics, and help info as well (once extracted and downloaded)
I wouldn't use it yet though (ie unsure of the remifications)

Hi
I believe that I may have to take a much closer look at this chip and alot more homework . The circut just doesn't look right for a standard cmos-security chip. However I do all my work on IBMs and I could be way off the mark with this one. So I will keep on looking and keep on tryng to figure out this one.
Any and all help is apresiated. Please desregard my spelling errors,I'm using an old laptop with a bad keyboard.
Thanks

grc1,
after 3 unsuccessful tries to enter password, X200 should give you error code 5 digit.
...

Hi , After three tries I get an error message.
system disabled 12261
Thank you

password is 1221576

That is really cool. The password works.

Thank you

sorry, but I told you exactly what you need to do with the dst cd and that it would not change anything if you remove the batt.
so you should not say "thanks for no help". thats just not fair.

Im looking for 595B DELL PASSWORD GENERATOR, any ideas?
