NAME

crl - VAX 8600 console RL 02 interface  

DESCRIPTION

This is a simple interface to the DEC RL 02 disk unit which is part of the console subsystem on the VAX 8600 and 8650. Access is given to the entire RL 02 disk; the pack format is the same as that of RL 02 disks on other controllers. As on other VAX console media, transfers are done a word at a time using privileged registers (i.e., slowly).

All 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 ``raw'' disk interfaces. (Although the sector size is actually 256 bytes, the driver allows operations only on 512-byte boundaries.)
