	At the meeting I was given A1h for the 12 byte command pass-through,
85h for the 16 byte command pass-through, and 09h for the return descriptor.
These opcodes apply to both SBC and RBC.  I will have a new document up next
week with the proposal modified for inclusion into SAT.

My friends and I were on a beer run and noticed that the cases were
discounted 10%. Since it was a big party, we bought two cases. The cashier
multiplied two times 10% and gave us a 20% discount...  and then he voted.

The draft "CAP Working Group minutes - Nov 9-10, 2004"
document noted that the ATA command pass through (16) SCSI command has been
allocated opcode B5h.

That is a 12 byte opcode which SPC-3 rev 21a lists as "Trusted computing Out
[proposed]". Perhaps B5h is a typo and should be 85h which is an unused 16
byte command.
