I haven't tried (it wasn't an option until the patch was available). However, I suspect that 2.1.5 won't even recognize the CD there.

It simply doesn't have a free slot, so upgrading to SCSI means replacing the whole thing... > > Enjoy, > -- > Jason Garman http://www.nesc.k12.ar.us/~garman/ > Student, Eleanor Roosevelt High School garman@phs.k12.ar.us > Nadav
