recommendation that the Tailgate 
document [D1248r4] be letter ballotted for forwarding to NCITS. The letter 
ballot closes September 10.

SBP-2 [T10/1155D]

There was discussion about how to get the correct group of people to 
address isochronous issues. This is the 
area of SBP-2 that is weakest.
Action - Pete McLean - to address issue in joint meeting on Wednesday.

Printer people want to add another ORB that will have a bi-directional 
pipe. Peter Johansson agreed  to 
make up a proposal for this and will add an example with the proposal. 
Peter will bring the proposed 
document to the Oct. 7th meeting.

Power up issues - Jeff Wolford stated that Device Bay has decided to allow 
no power state changes by 
anyone other than the logged in device with correct password. No 
additional power may be used prior to 
successful login. After some discussion it was concluded that this need 
not be addressed in SBP-2 as it will 
be delt with in the Device Bay specification.

Page by page review of the annexes in SBP-2 including the new annexes from 
STS and clauses 6 through 
10 was held. Numerous editorial changes were agreed to and Peter Johansson 
will turn a new revision 
reflecting these changes. At this time all of SBP-2 except clauses 11 and 
12 have undergone editorial 
review.

SBP-2 Device Attachment

The draft project proposal for the document prepared by Pete McLean was 
reviewed and accepted.

The body of the document, annex A, and a portion of the removable media 
annex were reviewed. Two 
issues were raised:
1. Are power mode timers required? Jeff Wolford and John Fuller will 
investigate this and report back at 
the next meeting.
2. Is SMART status polled? Jeff Wolford and Tom Lenny will investigate 
this and report back at the next 
meeting.
