Page 2-17 shows how to clear CMOS. You may be able to get it to work by clearing CMOS using your current battery, but more likely will have to wait until you get a new battery. In either case, you will need to get into BIOS settings at some point to reload defaults or make necessary changes. Once again, the manual will help you.
I was guessing the battery could have died, but I have never experienced it so I thought I would get some input.
And there is a floppy drive, but it's unplugged. I will unselect it as soon as I have time to do so.
I will post with results asap.
