Brichardi05,

Unfortunately, there is no software to enable changing the bios pw on multiple systems.

There is Support for this but its not free.  System Center Configuration Manager (SCCM) to deploy, update, and lockdown the BIOS on Dell systems using Dell Command | Configure. (This is the new Name for OMCI)

Setting a BIOS password on a machine that did not previously have a BIOS password set is not possible for security reasons. 

The other way is via PowerShell Script and OMCI

Change Bios Password a way to automate the change of the bios password.

Requirements: Dell System, OMCI v8 or above, PowerShell 2.0

Thanks speedstep for sharing the script. 

In my organisation we are using over 700 dell optiplex series desktops. 

dell optiplex 3020

dell optiples 3040

dell optiplex 7050

i use PDQ deploy to upgrade the bios to latest version with silent code. 

The problem is each and eveytime i must redeploy the package with different set of bios password credentials.. 

What i planned is to change all bios password to one unified password so that i can deploy various bios updates and as well as Dell command configure multi package  to disable front usb. change boot order. power on methods. disable sleep mode.. etc.. 

I tried ur script but i get error and also i dont know where to fetch input of computers hostnames to change the bios password remotely. 

please suggest your ideas..

Awaiting for your reply
