Access is given to the entire .Tn RL Ns 02 disk; the pack format is the same as that of .Tn RL Ns 02 disks on other controllers. As on other .Tn VAX console media, transfers are done a word at a time using privileged registers (i.e., slowly). .Pp All .Tn I/O is raw; the seek addresses in raw transfers should be a multiple of 512 bytes and a multiple of 512 bytes should be transferred, as in other .Dq raw disk interfaces. (Although the sector size is actually 256 bytes, the driver allows operations only on 512-byte boundaries.) .Sh FILES .Bl -tag -width /dev/crl -compact .It Pa /dev/crl .El .Sh SEE ALSO .Xr arff 8 .Sh HISTORY The .Nm driver appeared in .Bx 4.3 .
