I recently created a vlite distro of vista ultimate, and noticed after the unattended install now my computer beeps when it boots up. It can last up to 5-6 seconds or until i hit a key on the keyboard and it is happening after it gets through BIOS. After either scenario however, it boots right up into windows. I installed on a dell e1405 laptop, 2Ghz Core duo with 120GB hd, and 2GB ram. Last_Session.ini
