Sharp PC-7100 Configuration Question

I have a question regarding a Sharp PC-7000 series computer. I think mine is a 7221 or such. It has a hard drive and a floppy drive (FDD) My problem is that when the computer boots up, I get a "configuration" error. I can hear the HD spin up but apparently there is nothing on it. The "configuration" error says to strike F1 to continue and when I do, I get an error that indicates that the device is not a boot device. The FDD is never accessed and the FDD light never lights. So, my questions are these: 1) Is there a source for the configuration diskette somewhere on the internet, so that I can get a copy of that diskette? 2) What can I do to reset the configuration, since I don't seem to have FDD access? Ctl-Alt-Setup does not seem to allow me to set the FDD to boot. Thanks,
