Hi Folks!
I'm looking for informations about retrieving BIOS info but I found only references that uses WMI classes to do it.
That's not what I want because WMI is too slow.

Is there a way to get this information from a Ring 3 application or just from Ring 0?

Thanks in advance!

Really? Too slow? How many times a second are you intending to get the serial number?

Only Ring0 Starr can do this for you. Hey, that's a Beatles reference folks.

Well mate, I'm coding in fasm I want to do it as fast as I can no matter how many times I'll call the function. Besides I want to know what is happening under the hood and thats's the reason I don't want to use WMI.

Since this thread is in Windows, what about

Code:
HKEY_LOCAL_MACHINE\HARDWARE\DESCRIPTION\System
     REG_MULTI_SZ: SystemBiosVersion

I saw this registry key during my research thanks kandamun.
If I find a solution to access this information using assembly without having to use the registry I'll post it here.

Thanks everyone who answered this thread!
