A SGI boot CD has number of heads set to one. That should be fixed easily - But this shows there is something wrong with reading 512 byte blocks from a cdrom - I think we get low-level (Read: scsi) errors when trying to issue a scsi read request on non 2048 byte aligned boundaries or something. One would need an scsi bus analyzer to actually get more reasonable knowledge of what going on.
