9.
Problem:
Implication: The result could be a hang of the parser state machine or incorrect setting of the state variable in
Workaround: Do not use non-pipelined state variable execution when the interrupt ring is enabled. DVD
Status:

Problem:
Implication: The GMCH A3 stepping may not work properly if LMD13 is floating at reset. The system may not
Workaround: To compensate for any possible floating condition, add a weak pull-down resistor (10 K –20 K )
Status:
11.
Problem:
Implication: Graphics corruption such as vertical stripes may appear while moving around an active AVI or JPG
Workaround: None identified. Using CAS latency 2 memory reduces the problem.

Data Decoded As Command during Low Priority to Interrupt Priority Ring
Buffer Transition
Data is decoded as a command packet if the low priority ring is executing non-pipelined state
variable packets and the interrupt priority ring is enabled. This could happen anytime 3D is active
and a stretch-blit (2D) operation is conducted through the interrupt ring.
3D. The only known application that uses the interrupt priority ring is the stretch-blit operation.
Intel drivers associated with the 82810 do not use this process. This process is used by DVD
software.
software writers are aware of this issue and can modify their DVD software to avoid this erratum.
Please contact your DVD software provider to determine if this erratum has been addressed in their
current DVD software and if a software patch is available for earlier versions of their DVD
software.
No planned silicon fix. Software fixes are already in place.
