I have a Compaq Presario 5151 running Win. 98. I want to replace the IDE zip drive that it came with with a rewritable cd drive. I was told that I would have to uninstall the VIA bus master and let Win. 98 set the Win. default IDE controller to get it to work. I can not get much help from Memorex, and Compaq's suggestion was to take it to a service center. Please help.
