Dunno, Wiz. I downloaded CR563B drivers from driverguide.com but when I tried to load that 95 said it wasn't drivers. The old Matsushita doen't have master/slave jumpers -- just a1-2-3-4 which I found means [after looking for 'bout and hour yesterday] that you have that many drives on board ala SCSI. Tried the Iomega set as master and the Mat as "1" and "2", but no dice. Haven't tried leaving the CDRW and booting from a diskette, but will do so in a second. Also, the only reason for the Mat disk was to install the 98SE. Other than that it is spare parts trash culled from another old junky PB system!
Thanks, I'll let you know about the boot floppy try.
