<p><b>Notes:</b>
Sends SCSI Read Capacity command with the PMI bit set to obtain the
logical block address of the last block after which a substantial
delay in data transfer will be encountered (usually the last block
on the current cylinder). No translation to 512 byte sectors is
performed on the result if data is stored on the disk in other than
512 byte sectors..
The TMC-950 does not support any Future Domain BIOS calls; instead,
it provides a full CAM implementation (see INT 4F/AX=8100h)
