We have a Dell Optiplex GX260, with a Phoenix ROM BIOS PLUS Version 1.10 A05. This machine was given to an employee by a corporation, who set what I will call a power-on password. This is not just a Bios Password, no OS can boot until you put this in. I have been over the web trying to find a solution, we took the hard drive out and retrieved their data, but we are left with a useless machine at this point.
I have tried taking the battery out, overnight, and while it seems to reset some CMOS settings, for example, it has to do an IDE configuration, IT DOES NOT WIPE OUT THIS PASSWORD! I have tried the lists of "backdoor" passwords for the phoenix bios, and also tried the word "dell" which I have seen.
Here is the exact syntax:
Type the password and ...
- - press <ENTER> to leave password security enabled.
- - press <CTRL><ENTER> to disable password security.
** Incorrect password. **
You get 3 tries, then it goes
Number of unsuccesful password attempts: 3
System halted! Must power down.
When you do power it down, and power back up, it only gives one try and keeps incrementing by 1 Removing the battery does reset this count, but that is all.
