:
CmosPwd is a cmos/bios password recovery tool.
CmosPwd is under GNU Public License. You can freely distribute it.
It can be compiled under Dos, Windows, Linux, FreeBSD and NetBSD.
Platforms
- Dos-Windows version
Well, ... it works!
- Linux && BSD version
Users can work on cmos backup but they need root priviledge to
use ioperm function to have full access to cmos.
- Windows NT, 2000, XP, 2003
To work on cmos memory, ioperm need to be installed and running.
ioperm gives direct port I/O access for specified ports to user-mode process
(ring 3) using Ke386SetIoAccessMap and Ke386IoSetAccessProcess kernel functions.
1- You need administrator priviledges to install this driver
"ioperm.exe -i"
2- Start the service if needed with "net start ioperm"
3- Run "Cmospwd_win.exe"

Typical Usage for DOS and all Windows users
---------------------------------------------------
---------------------------------------------------
1) Identify your BIOS manufacturer (usually displayed at boot-up)
2) Start in DOS, or start a DOS session in Windows 95/98/ME.
For Windows NT or Windows 2000 boot from a DOS or Windows 95/98 boot
disk (you can find boot disks at www.AnswersThatWork.com), and run
CMOSPWD from your boot floppy (or another floppy).
3) C: [Enter]
cd \CMOSPWD [Enter]
4) Type CMOSPWD at the DOS prompt and press Enter.
5) CMOSPWD will display a list of possibilities. Use the possibilities
itemised against your BIOS manufacturer.
Remember :
a) For AWARD BIOSes, use the Numeric Keypad (with NumLock ON).
b) AWARD 4.50PG BIOS always accepts "AWARD_SW", or "d8on",
or "589589".
c) Old Phoenix BIOSes will accept "phoenix".
6) If the standard method does not work, then try to kill
the CMOS password with CMOSPWD /K (and press Enter),
and then see if you can get into the CMOS without a password.
If you can, you successfully "killed" the old CMOS password.
DO NOT KILL THE CMOS ON LAPTOPS!
