First, write down your BIOS configuration before doing that again.
And yes you have to take the battery out form maybe 48 to 72hours sometimes to reset the bios.

Give a try!

You can't rely on just taking the battery out.  It's possible for the CMOS to retain it's data for days on some chips.  You need to move the jumper to the SHORTING position.  Check either the motherboard handbook or the silkscreen on the motherboard for the jumper position to short the CMOS and erase it.  On some systems is a separate jumper, on others it's a different position than the normal operation.

Jhance..
I'm glad you offered that solution, I'm always very relunctant in asking someone to short the motherboard.  You know what I mean, they will always blame you if something goes wrong..
Anyway, I should go to rest, I have been working for the past  >>>> 22 hours approx. (graphics project)

i will try that after my next reboot, but it will have to b marked on the silk screen, as i dont have a book for the m/b :(

but i would rather a pwd cracker, i do have the source code for one but could not find a compiler for it, i think it is in assembly language

Back Door passwords for bios?
Back Door for AWARD bios: AWARD_SW
Back Door for AMI: AMI

Simple enough?

Joel...

That would be the default until changed..
Once it's changed, would that Back door still work??

jrhelgesonCommented:
These are default backdoor passwords, they do not change even if you program your own password. However, I just realized that it may be dependant on the motherboard manufacturer, I wonder if they can disable the back door?

I am e-mailing a URL to the_q58 that contains several AMI, and Award bios cracking/decoding utilities.

The URL is: http://www.ilf.net/madhattar/Archive.html

all the pwd crackers return garbled text ( which aint the pwd)

which suggests it was meant for an older bios :(

magigrafCommented:
Sorry to hear that, but what's your next move??
Remove battery, or short the motherboard??

jrhelgesonCommented:
If you tell me the exact layout of your motherboard, I will be able to tell you the brand.  Then I can give you the exact jumper to use. :o)

I will need:
CPU Class, 486, 586
# of 16 bit slots
# of PCI slots
# of vlb Slots
Chipset
does it have the following on the board?
model #, serial, parallel, hdd conn, floppy conn?

Just to throw anothe couple of cents into this discussion.

I have removed passwords on some of my machines at work simple by taking the jumper off the 2 poles and then putting it back on.  You won't lose or hurt anything if you pull the wrong jumper off and put it back on the same 2 polls.  These are Dell computers and am not sure if this would work.  However, this is what the Dell user manual said to do.

Can you see any model number on the motherboard?
When I said "model #, serial, parallel, hdd conn, floppy conn?"
Let me clarify:

Model Number: any white lettering that looks like it might be a model number.
Serial: Serial Port adapter.
Parallel: Parallel Port adapter.
HDD conn: Hard drive connectors, if there are any on the motherboard.
FDD conn: Floppy drive connectors, if yours is on the motherboard.

PCI Slots, 16 bit, VLB? do you have any? How many, If you cannot tell me that simple information no one here can help you.

THERE IS A JUMPER ON YOUR MOTHERBOARD, this jumper exists on EVERY SINGLE MOTHERBOARD EVER MADE! If disconnecting your battery for 72 hours does not work then you need to locate the jumper and disable it.

If you are not capable of providing even the simplest information, I cannot help you. Nor can anyone here.

Pop open your case, take out your battery and then take a paper clip. Bent the paper clip out like a "U" touch both conductors on the mommyboard where the battery once was, with one end of the paper clip touching a different side of the conductor. Hold it there for about 30-45 sec.

I hope i helped and you understood what i was trying to say.

In 3 words it means
" Short the motherboard "
Which has been offered before!

the_q58Author Commented:
well the prob is solved, i just moved the jumper closest to the bios chip to all positions, which worked.

so now i have no idea to give the points to jhance i guess seems how he said it first ?

LintCommented:
Looking back at history jhance said it first..

But I agree with magigraf , One hates to suggest that with out lots of warnings (grin).

If you have access to dos you can use simple utilities that clear the cmos. If this is your situtaion, give me your email, and I will send this small program to you (66Kb)

avi_shava...

Now think about what you said again. (actually you did as my first wrong answer)

How could he access DOS if he can't boot??
The machine is waiting for a password to start.


I believe that your answer is not valid.
