I am currently in the beginning of writing a device driver for the 
DEC RX01 / RX02 floppy disk system. These drives use 128 or 256 bytes
per sctor. How does NetBSD deal with this? Is there a system to use non
512 byte per sector disks, or should my driver do a transparent sector
mapping to 512 byte sectors. (Like the firmware of SCSI CDROM drives in 
512 byte per sector mode.) A first look at disk(9) did not gave me
a hint.
