okay... i'm lost... my computer(from 1999) has run perfectly since to day i got it. now its giving me odd error messeges before i can do anything with it. it starts from about 2 seconds after i turn it on. i see the black screen with the big gateway logo on it, then it just suddenly goes all black, beeps twice and shows the message 'A: Drive Error press <ESC> to resume' so i press ESC. then it thinks for about half a minute and gives me another error message 'Boot Failure Insert Boot disk in diskette A: Press any key when ready' and here is where i need help. i have no clue what its asking. please help! any pointers would be useful!
