¦ 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 http://www.AnswersThatWork.com ), and run
    CMOSPWD from your boot floppy (or another floppy).

  3. C: [Enter]
    CD\CMOS_Pwd [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".

  1. 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 IBM ThinkPad 765 laptops.

  2. If you cannot kill the CMOS with CMOSPWD, then try the following,
    all done from the DOS prompt of real DOS or of a DOS session :

DEBUG [Enter]
O 70 2E [Enter]
O 71 0 [Enter]
Q [Enter]

(The first character of each line above MUST be a letter, so whenever
you see "O", read it as the letter "O" and not the digit ZERO,"0").

General Usage (List of commands)

cmospwd [/d]
cmospwd [/d] /[rlw] cmos_backup_file restore/load/write
cmospwd /k kill cmos
cmospwd /m[01]* execute selected module

/d to dump cmos in ascii and scan code
/m0010011 to execute module 3,6 and 7

Keyboard:
/kfr French AZERTY
/kde German QWERTY
default is US QWERTY

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 && W2K
    Users can work on cmos backup. To work on cmos memory, gwiopm need to be
    installed and running.
    gwiopm gives direct port I/O access for specified ports to user-mode process
    (ring 3) using Ke386SetIoAccessMap and Ke386IoSetAccessProcess kernel functions.
    You need administrator priviledges to install this driver
    "instdrv gwiopm c:\tmp\gwiopm.sys"
    To remove the driver, run "instdrv gwiopmremove".

Laptops

The password is usually stored in an eeprom on the motherboard, you need an
eeprom programmer (electronic device) to retrieve it.

Compaq M700: eeprom 24C02
Dell Inspirion 7500: eeprom 24c164
Dell Latitude C600: eeprom 24c02, password in scan code at 0x98 and 0xA8
Dell Latitude CPI: password in scan code at 0x00, 0x10, 0x80
IBM Thinkpad X20: eeprom 24RFC08CN, password in scan code at 0x338
IBM TP 380Z: eeprom 24c01, password in scan code at 0x38 and 0x40
IBM TP 390: eeprom 24c03 (be carrefull, there are two eeprom)
IBM TP 760C,765D: eeprom 93c46, password in scan code at 0x38 and 0x40
IBM TP 770: eeprom 24c01
IBM TP 600E, T21: 14 PIN 24RF08 (see http://www.ja.olm.net/unlock )
HP Omnibook 4150,7150: eeprom AT24c164, 0x6D-0x7F area, unknow algo
HP Omnibook 6000: eeprom 24c08
HP Omnibook XE3: eeprom 24c16
HP Omnibook 770x: eeprom 24c01
Toshiba 74600C: eeprom 93c56

You can get/buy eeprom programmer in electronic shops or labs, you need
another PC to use it.
You can desolder the eeprom with hot air or you can try to "clip" the
eeprom. With the eeprom programmer, backup your eeprom and run
"cmospwd /d /l eeprom_backup". If you don’t see the password, you can try
to fill the eeprom with zero orFF.

Toshiba

Differents passwords give the same 32-bit CRC, so CmosPwd can only give one
of them.
To reset the password of an old Toshiba, you can use KeyDisk. (cf my web page)
If this doesn’t work, you can try to build the Toshiba Parallell loopback.
To make a simple device that you connect to your parallell port, a lot of
Toshiba computers remove the password when you boot it up.
The device, named "loopback" by some, could be made out of any
parallell wire with 25pins connectors (db25). You should connect
these pins: 1-5-10, 2-11, 3-17, 4-12, 6-16, 7-13, 8-14, 9-15, 18-25.

A db25 looks like:
1 13

14 25

Divers

  • Award 4.50PG
    There is an universal password AWARD_SW.
    (d8on, 589589 … works too)
  • Award
    Differents passwords give the same 32-bit CRC, so CmosPwd can only give one
    of them. Use the numeric keypad.
  • COMPAQ LTE 5300 notebook
    Tolga Sinan Guney: there is a reset jumper on the motherboard
  • DIGITAL PC300, Phoenix 4.0 Rel 6.0,0
    Rene Pocisk: cmospwd /k works
  • Fujitsu ICL
    aksion: passwords are stored in EEPROM
  • Phoenix
    There is a backdoor in old version of Phoenix BIOS, the universal
    password is "phoenix".
  • Siemens Nixdorf
    PCD-4ND, Michael: You can clear the password of this phoenix 1.03 with "cmospwd /k"
    Scenic Mobil 700, Josef Benda: "cmospwd /k" works! Phoenix Note BIOS v4.0

What to do if you can’t use cmospwd to clear your cmos ?
You can use debug to reset cmos CRC stored at 0x2E-0x2F
debug
-o 70 2E
-o 71 0
-q

What to do if cmospwd don’t work on your PC ?

Try to clear password with cmospwd /k.
If cmospwd /k doesn’t work, password is stored in an EEPROM. Try to find a
reset jumper on your motherboard or contact your PC vendor.
If it works, I can try to discover how passwords are encrypted.
I need to know what Bios you used and
some cmos memory backup with their passwords. (cmospwd /w backupfile)
For passwords, choose

  • some 1 and 2-letter passwords
  • BBBBBBB
  • BBBBBBC
  • BBBBBCB
  • BBBBCBB
  • BBBCBBB
  • BBCBBBB
  • BCBBBBB
  • CBBBBBB
