Re: Forgotten BIOS or Boot password for Dell Latitude CPi D266xt
Note: This is for Dell CP and CPI Latitudes, it has not been tried on
other models. Another way to crack it is to create a short in the 24c02
chip (the markings on the top of the chip) between pins 3 and 6 when
you power on!
The chip is below the processor so you have to solder two very small
wires and bring them outside the laptop then reinstall the processor.
Short the two wires and power on! Pin 1 is the one with the dot in the
corner. Next pin on the same side is 2 then 3,4, and 5,6,7,8 going
around the corner with pin 8 being across from pin1. The power on
password will be disabled and you will be able to access the system
settings via the F2 during bootup as if it was never there. This works
for me, works great.
For those of you who are not accustomed to soldering PC boards. Make
sure the wire does not touch other pins or the case. Do NOT OVERHEAT
the chip! Work in short sets of applying heat and let it rest a few
minutes between attempts if you can not get it to attach right away. No
more than 8 seconds at a time at low temp setting.
I used some old "wire-wrap" wire. It is very-very small, single
solid strand, and insulated. Be sure to ground the solder iron to the
case just before you solder and REMOVE THE BATTERY FIRST!

Re: Forgotten BIOS or Boot password for Dell Latitude CPi D266xt
Hey - this definitely works! I had a couple of CPi chassis sulking in a
corner just waiting for the light of day - one a 266 and one a 400.
Although the 24C02 were in different locations under the CPU, they both
worked a treat. Just to clarify the procedure, as Bruce says you short
the pins, press the power button, remove the short, key F2 to go into
bios, ESC out of bios and the password is gone. Many thanks Bruce - I
can clear the corner now!
