Here is the software I promised for editing Dell bios. It allows you to remove bios lock on laptops, desktops, and servers. The software is bootable. You can edit a lot of bios features including asset tag and service tag. I have provided this in .ISO format. You can view information about the software in the readme provided. I got this software at work and use it frequently. It works on all models every time as long as the boot configuration has not been disabled. If you have a bios locked system press F12 at the startup screen to select boot choice. The boot from CD-ROM or DVD-ROM. Type /help for a list of commands. The software is currently set to remove bios lock and flash bios on startup and then allows you to change service tags. This is Dell internal use software only so lets keep it a secret. http://pcemporium.webs.com/Dell Bios Reset.iso Enjoy!
