hey all I have a computer with a bios password and there is no way to reset
it using jumpers or grounding points on the board the cmos chip is a
DALLAS DS1587. I looked on the net for this chip to reset it with no luck.
If any one could help me I would be greatfull.

There's always shorting it out:

Go back thru this group a day or two there are a few threads that
could help you out as well.

been to this website and tried what it said with no luck even tried the
default passwords

Use this http://www.cgsecurity.org/index.html?cmospwd.html

thats no good either seeing i cant get passed the password to boot the
system

You need to copy it to a floppy and run it from there, the dos version.

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!

|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

---------------------------------------------------
---------------------------------------------------
|Laptops |
---------------------------------------------------
---------------------------------------------------


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

write zero at 0x0
the ic is behind the modem in the top side of the board

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 or FF, don't forget the reset the cmos.

---------------------------------------------------
---------------------------------------------------
|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:

name on front of system is Data General AViiON
this is the mainboard for the system
ZDS ATX AT Motherboard 181571 part# pba 637919-052
Bios chip is a DALLAS DS1587 (not on any of the pages i have looked at to
date)

im sure someone out there have played with this server befor and either
has a manual or knows how to reset the bios on it
grounding out the bios pins dont seem to work.

Please repost with more information, including the make and model of the
problem computer and any information on the motherboard.

ok once again the system does not boot for there is a password it asks
for befor it even starts.
2nd jumping the bios chip does not work tried it many times
there has to be somthing on the main board or some sort of disk needed is
all i can see to fix this problem

hmmm you think maybe a large hammer might get it to boot or a stick of
T'N'T

any ways i do thank you all for helping me with this its just this thing
is going to drive me mad here soon
I want this thing up and running so i can use it
