In many Alcor Micro controllers (e.g., AU6476 card reader or AU9540 smart card reader), vendor-specific registers reside in the range 0xFA00 to 0xFAFF.
If you spend enough time digging through Windows Device Manager, Linux terminal outputs, or obscure hardware forums, you will eventually stumble across a string of text that looks less like a device name and more like a secret code. alcor micro unknown fa00 f w fa04 top
One of the most elusive of these is the string: "Alcor Micro Unknown FA00 F W FA04 Top". In many Alcor Micro controllers (e
It doesn't roll off the tongue. It isn't in the manual. If you try to Google it, you might only find a handful of confused users asking, "What is this?" and "Why is my CPU usage spiking?" It doesn't roll off the tongue
Today, we’re putting on our detective hats. We’re going to decrypt this alphanumeric soup, figure out what this piece of silicon actually does, and tell you whether you should care.
The FA00 chip is often a masked variant of the AU6370 or AU6371 series. You can try the driver for those:
