BleepingComputer.com: Check for Supervisor Password in BIOS

Hi

I am wanting to send out either a tool or a script that will check all the desktops and laptops in my clients organization for a BIOS Supervisor password. They are all Lenovo Thinkcentres or Thinkpads running XP Pro. I think this is possible as i have IBM Standard Asset Manager installed on my Thinkpad and it scans for a Power On password and a Hard Drive password. I'm having trouble finding anything on this as every search i have done brings back info on cracking the passwords! There isn't even that much info about IBM Standard Asset Manager. Any help would be appreciated.

Thanks in advance
