Windows 7: access to BIOS through Windows?

access to BIOS through Windows?

Title says it all. I'd like to access BIOS remotely, and the vnc connections I have all work through Windows. Is there any way to do it?

It is impossible to access the computers BIOS within Windows, even remotely. You'll literally need to access the BIOS from the physical system. When you access the BIOS, the Operating System's boot sequence is not operational. As soon as the BIOS POST tests complete, the system will then proceed to boot from the hard disk which then starts to boot up the OS.

Conclusion: As above, it is not possible to access the system BIOS remotely.

Hi and welcome to SevenForums,
ASUS does have a utility called AI tweak 2 or 3 that allows bios settings changes from inside the os
Mostly for over clockers and system fan changes that I've noticed in my brief tour of it
Other manufacture may have utilities similar.

Thanks. Oh well. I'll have a look at ASUS AI. But that's really a pretty significant demerit to the whole PC architecture, that you can't do very basic things remotely.

In a general sense it is not possible to access the BIOS through Windows. The reason being that the BIOS is proprietary to the manufacturer. Where and how the BIOS stores it's settings is not documented and even Windows has no way to obtain this information. Only the BIOS configuration software built into the BIOS can do this and it cannot be accessed from Windows. The only exception would be with a utility supplied by the BIOS manufacturer designed for specific versions.

It would be convenient to access the BIOS from Windows. But convenience is not always a good thing. The problem is that if Windows could access the BIOS it could also be done with other software, including malicious. That would open up a whole new world of mayhem for malicious software, one which it's authors would take full advantage of. Protection methods could be devised but they could be evaded. BIOS viruses do exist but they are rare and very BIOS specific.

Good points. But that's not a particularly good argument for having the BIOS separate from Windows. By that metric we should divide Windows up into pieces, each controlled by a different manufacturer, and only addressable separately. That would really cut down on malware, no? It would also hugely cut down on convenience and efficiency. The fact that you can't remotely control a PC at root level is, at least from where I sit, a major disadvantage.

Do you have any kind of idea as to the damage an attacker can do to a computer if it is that exposed? Files can be restored, programs and operating systems can be reinstalled but a computer damaged at the BIOS level would have to be replaced. There are good reasons why the OS is separate from the BIOS. Realistically there really isn't any other way to do it since the OS is software and the BIOS is hardware.

Hi,
Indeed pretty much why I got rid of AI tweak .. it's seemed more of a issue waiting to happen than any type of needed feature to me
Why have a utility around to make it easier for the bad guy's

I'm not understanding why one would want to access the bios through Windows.

Dramx please enlighten me.

If one could reach the bios using Windows 7 you still would have to reboot before the changes would take effect.
