Write to BIOS from XP

[danis]

Hello!

I know this is not the best place to ask this question, but because
there are a lot of experts here, I take my chance.
What I want to know is if it's posible to make a BIOS setting from
Windows?
More precisely, I want to set the RTC alarm to some terminals, without
having to connect a keyboard to each one of them, and thus setting it
manually. What I was thinking, is to make an application, that acceses
a DLL with some API functions, through which I could set this setting
into BIOS, from Windows (XP or XPE).
Do you know or think that this is posible?

Thanks!

Hi,

This is possible through a DLL.

We have previously successfully used "Win95io.dll" from a custom application
to set BIOS / CMOS values.

You ned to find the address where RTC is stored and also calculate new
checksum.
