CD Burner Conflict.

I have an old Dell running WIN98 SE. When booting the machine the CD burner light starts flashing & doesn’t ever stop. The burner is not accessible. This happened shortly after installing a new multifunction HP printer/scanner on a USB port. No help at all from HP FAQS. Printer only has USB or I’d try a serial cable.

The machine shows no conflicts in device manager. Not sure what to do on this one.
