Notes: the CAM committee moved the interface to INT 4F after revision 1.9

to avoid conflicting with the IBM SCSI interface and the Virtual

DMA specification

the only driver to date reported to use the CAM interface on INT 4B

instead of INT 4F is from Future Domain (which has drivers for CAM

on either interrupt)
