Is there a way - thru VB - to set the Bios password at all? I don't need to know what it is, but I need to be able to set a new one. Also, is there anyway a VB program could survive a format to a hardrive? Thanks alot!

What are you writing? The next HD virus? Blast out the BIOS password and still be viable after a reformat? What legit app needs to do that?

Mirk? Didn't this Q strike you as *odd*?

My answer basically,
says NO cannot be done and no it cannot be done.

Depends on the format. A QuickFormat doesn't destroy any data, only the FAT. An unconditional format destroys everything.

Nope, there are ways to still leave data on a disk after a regular format and an fdisk...

This application is not the next "HD Virus" at all. It is simply an application that is used to request passwords from the user. The company I'm working for sells PC's to people who have really horrible credit. But, the finance company wants an "insurance" that they won't skip their payment. So, what we thought was to have them call or dial in every month and get a new password that allows them to operate the PC for another month. As long as they pay their bill each month they'll receive the new password. If they don't, the PC will not operate. So, no, I don't need a way to "blast" out the bios password, since the user will know that password as long as they make their payment. I just needed a way to set it with their new password. We probably need to also look at what this forum is being used for. If I really wanted to make a hardcore virus, does anyone think that I would use Visual Basic to do that with? Also, there are other Security companies that sell PC software that will survive hd formats. Thanks for all who responded. I do appreciate any response that I might get.

It is viable to do this, and VB unlike other languages is the shortest language to use to create a virus . (short of assembly)

Well, still, I'm not trying to make my program "impossible" to delete or get rid of. In fact there is an uninstallation of it. I just want to make sure I don't allow a person to get a free PC. We put alot of money into these PC's and we're just trying to safegaurd ourselves from theft. I think people with poor credit should have a chance to have a PC as well as people with really good credit. And this is the only way we can convince the financing companies to finance more underqualified applicants - if we secure the PC for payment. Kind of like the Light company or Cable. It's easy for them - if you don't make your payment eventually you'll have the lights turned out. Or the cable disconnected. Now, there are certain people who try and find a way around paying for cable. That's why the cable company makes it hard for them to do that. All I need are some deterrants.

No software protection is 100% safe.
Burn your own bios I would say...
You can program anything in your own bios
