Our cd writer is on a linux box, and the special minor number for wd0 got truncated from 0x10002 to 2. What's interesting is that this never caused trouble until we hit a dos-partitioned disk, i.e. all the failures I'm having I never had on an unitialized disk. interesting. Wish I could have convinced the vendor to leave the disks untouched. For those of you writing CDs: run mkisofs on a freebsd box! The other question remains. Where does ezboot come from? ron
