Trying to get into the BIOS

Guess my luck is lacking, I tried entering a few different values in
DEBUG as found here and there, to no effect so far...

Try the ctbios utility from here:

http://www.biosflash.com/e/bios-passwords.htm

the output is in German, but not hard to follow. That may show you what
the password is.

I had the same problem with an HP Vectra VL420 motherboard last week.
This uses a modified Asus P4B-MX board. An unknown password was set on
the BIOS setup so I could not configure the machine.

The debug trick worked to deliberately cause a CMOS checksum error, but
it didn't get rid of the password. Googling found me a link with a tip
to set a certain jumper to clear the passwords and that worked.

I tried the ctbios utility above but that didn't show me anything that
looked like a password.

If you google for "BIOS backdoor password" or "BIOS master password"
you'll get a lot of hits with lists of different passwords to try.

There will be a way to do it, just persevere.

So, at this point I've still yet to try KILLCMOS , still trying to
figure out what's with the values assigned to different flavors of
BIOS as listed in the program Cmospwd.exe

try "bcndk1" (I found that by googling "baracuda bios password")

Heh; I do agree that that is an excellent reason for swift thread

Bingo! Geoff, your google-fu is incredible, I never would have

thought to try that.

I got right into the bios, disabled write protect and the passwords,
then was able to
go flash the board into the most recent bios version. Sure was nice
to see the flash program complete like it was supposed to.

Many thanks!
Mike

Failing that, locate a copy of KILLCMOS, a small utility that writes
to cmos RAM and *causes* a checksum error there.  The result is that
on a subsequent bootup you will be directed to setup (without
requiring a pswd) where you can clear the pswd requirement.

When I tried out KILLCMOS I guess it really did kill it cause the
computer
shut down all on it's own - had a few minutes there I thought I was
SOL,
but it came back on when I cycled power to the 'puter - whew!

I think that somehow the flash memory was being refreshed after each
onslaught
against the checksums or whatever it was that those debug routines do.

Thanks for the link, I'll be checking that out tomorrow, but in my
leisure, as Geoff M. was able to come up with the right password -
what a great group!

Thanks to you all,
Mike
