I purchased a dell Inpiron e1505 laptop with a bios password. I thought I would some how be able to get around the password, but as of yet nothing has worked. I tried the following.
1. Removed CMOS battery 30 min.
2. Overloaded Keyboard and mouse buffer.
3. typed in eight spaces and some other backdoor passwords.
4. Removed the harddrive to force it to boot from a live linux CD (it will not even do this)
5. Tried looking for the chip were the password is stored to short it. But i could not find the chip.
Every thing i have tried does absolutly no good. When i removed the CMOS battery it cleared the settings in CMOS, because now when i boot up it says invalid CMOS configuration before it gets to the password screen. I found out latter the password is stored on a non-volotile chip. If i overload the buffers it just shuts down. And you can use absolutly no software approach because it does not even attempt to boot from anything until it has the password. So it all needs to be done on the hardware or password level.
Do any of you know of any possible way to get around this.
