How to get to BIOS on SONY VAIO E Series
1. Shut off the computer entirely. Wait until lights are off.
2. Press the red "assist" key once and do nothing else.
3. You will soon see a menu with bios set up as one of your options
Warning: I went into BIOS to password it. I saved it and tried to boot. On the first boot, it wouldn't accept my new password. It was a total freakout. I then discovered that if you shut it down and start fresh, it will take the BIOS password.
