Overview
Introduction
AMIDebug
™ Rx is a low-cost debug tool built around
the debug port feature common to today’s USB 2.0
EHCI controllers. Based on patent-pending technology,
AMIDebug Rx is designed as replacement for the PCI
POST Checkpoint Card, which is becoming less useful
in the PC market as newer systems omit PCI
expansion slots.
This product is targeted to power users, quality
assurance labs & service technicians. Diagnosing
platforms with AMIDebug Rx is non-intrusive, allowing
technicians to access checkpoints without opening the
case. AMIDebug Rx produces more descriptive
debugging messages than the checkpoint card, along
with extended features such as boot performance
timing and UEFI debug message redirection.
