Int 4B

Common Access Method SCSI interface (draft revision 1.9)

ES:DI -> CAM Control Block (see #03229 at INT 4F/AX=8100h)
InstallCheck:
Test for the string "SCSI_CAM" eight bytes past the INT 4Bh
handler

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)
