PCI Lock

Hi PCI Experts,

1.  If a locked transaction on destination/Secondary bus gets a SERR or PERR during address or data phase, then is the lock still maintained on originating bus as well as on destination bus. Will this hold true if the SERR or PERR is on originating bus for some transaction.

2.  Should a Locked Read Transaction on Originating bus be a DWORD only OR Burst or can be Both.

3.  Should a Locked Read Transaction on Destination bus be a DWORD only OR Burst or can be Both.
