I have successfully taken a bootable DOS ez135s catridge and turned it into a bootable NetBSD/i386 cartridge. I used pfdisk to change the partition ID to 165, made an /etc/disktab entry for it based on the geometry given by pfdisk (e.g. NOT the "real" geometry reported by the SCSI controller), disklabel'd the cartridge (which also installed biosboot blocks), newfs'd my partition and dump/restored an exisiting root partition. I suspect that one could do all of this starting with a bare cartridge, pfdisk, and the *BSD install floppies (e.g. I conjecture that no magic was performed during the initial step of making the cartrige a DOS bootable cartridge - but it was nice to have it scan and possibly remap any bad sectors). The reason to use to BIOS geometry is for the biosboot blocks. If you are not making a bootable cartridge, it will be fine to use the "real" geometry as reported by SCSI controller (which is what I originally did and had the same problem as you). Also, I think you'll want your Syquest SCSI ID to be 0. === Jason Brazile brazile@math.utexas.edu "People say I'm apathetic but I don't care" University of Texas
