Back in the FM1 times, I was so lucky to own this great motherboard.
This was one of the very few boards, which was able to use two digital ouputs at the same time.
I’d like to share with you the latest, publicly never available beta bios, which I’ve got from the ASRock support back in time.
Update: Add eip84455 to improve KB/MS compatibility.I don’t really understand the technical details behind the improvement, but this might be another check if the connected device is a:
- mouse
- keyboard
- hub
- storage
- point
- ccid
