If anybody can help me, i would greatly appreciate it!! I am on another computer, but the one I have won't even start up windows. I get the screen where it talks about primary drive 0 failure and primary diskette 0 failure. It asks me to press f1 to continue or to press f2 to run setup utility. If i press f1, i get a message that says press f1 to retry boot or press f2 to run setup utility. I run the setup uitlity, and under drive configuration my primary master drive is listed as Unknown Device. I looked at the event log and the most recent actions listed were something like CMOS battery failure, CMOS runtime error, and time and day not set. Do I really need to get another CMOS battery or can it be a software problem that wont allow my master drive to not be detected?
