Figure 79. AGP Left Handed Retention Mechanism Keep-out Information
Engineering Change Request number 48 (ECR #48) of the AGP specification details the AGP RM,
which is recommended for all AGP cards. These are approved changes to the Accelerated
Graphics Port (AGP) Interface Specification, Revision 2.0. Intel intends to incorporate the AGP
RM changes into later revisions of the AGP Interface Specification. In addition, Intel has defined a
reference design of a mechanical device to utilize the features defined in ECR #48.
ECR #48 can be viewed off the Intel Web site at:
