computer lock down

Does anyone know of a software program that will lock your computer even during bootup?Trying to keep people out of my computer isnt working.The screen saver password works, untill, they reboot the machine and then have full access.I want a program that will ask you for a password when booting, if the correct password isnt used, it will not boot up.I can change the password for my network enviroment, and if they dont put the correct password, it still boots into windows, and almost every file available to my desktop is available to them. I want to keep that from happening.

a lot of BIOSs (what's the plural of BIOS?) will allow you to have a password on boot. Hit 'f1' or a similar key when your computer is first booting to go into the setup.

edit: just remembered that before I got distracted, I was going to say that you could write something and stick it in your autoexec.bat file (if Windows still uses that...) ... but make sure it works correctly BEFORE you stick it in there.

ok i got it, i put a password in the boot. now it promts before it does anything.

BIOS - pl. BIOSes?

I needed to do such thing as well. I just made a console app (then putted it in autoexec.bat) that promted for a password if the pwd was incorrect it kept prompting for a password else the comp would startup... of course i figured there were ways to avoid this pawd app.

So i had a file somewhere on my comp that could keep track wether a pawd was entered on bootup or not...if not and windows was loaded then the comp would startt another app (window app) that would shut down the comp as soon as windows was fully loaded.

It worked great until it got stuck somehow, prolly a bug.
And since this was merely on a testing comp i had to format the whole thingh because i wasnt able to enter my comp without it having it shuut down automatically.

I think you could try something like this as well, as it isnt that hard to make.

::edit::
for those who say a bios pwd is enough

.... well IMO you can secure it as much as you want there will always be trix to avoid the security so ...

Well, GanglyLamb, if people are *that* determined to get into your computer, there is always a way. I'm guessing he just wants to keep family members off it or something though, in which case a BIOS password will be completely sufficient.

You just have to make sure your not stopping an ant with a bulldozer ;) .

Anyone heard of safe mode???

I did !!! ::hehe one-linerz::

If someone really wanted in, they could clear the CMOS.

And about the autoexec.bat thing, have you ever heard of CTRL+C?

Thats why i had that Win app thingy ;).

that's why you compile it as a stand alone app, no dos header, load it before dos...etc. Of course you'll have to use a bootstrap loader, but that's like 20 lines in asm, and you can get the code right offline. anywho, no ctrl+c, and they you can use fork() or other c functions to load dos, etc.

//edit:
in the professional world, that's referred to as 'nuking an ant hill'

Try this for ease of stopping certain snoopers. Not foolproof but at least a reboot wont fool it. :)
