For security reasons, i really need to setup a bios password on my computer. Although i have a security administrator program, and a windows startup password, these are rather easy to get around. I have a compaq presario 5461 if that helps.

I turn on the computer, press F10 to enter CMOSS setup.

I go into BIOS features setup and theres a security options category, but it says [setup] next to it & I can't do anything to change it.

The password setting in CMOSS is just a password to enter CMOSS Setup.

If anyone can tell me how to set the bios password, or perhaps a program that can setup one, it'd help me a lot. My family's been going through my outlook emails & other personal files, despite the security that i already have setup. (i've also hidden any personal files, and they've gone though quite a bit to access them)

Thanx for the help
