You can identify a pre-production FoxFire II adapter card by its EPROM tag, V1.1. FoxFire II cards that you can order now from PCI-SIG have the EPROM tag, V2.1. The production FoxFire II card is capable of measuring the 3.3Vaux voltage to determine whether the 3.3Vaux is within its regulation band while the system is in various system sleep states (e.g., S3).
