OK, I completely uninstalled the Fusion software ala KAXKID. I moved my card to my other PCI slot (only 2), reinstalled the software and ... no fix. It still had the beeeeeeeeeeeeeeeeeeeeeeee sound. I then tried OTA as it's a different input to see if that does anything and no luck there either.
I also updated my BIOS to the latest version and updated any other drivers available.
In case it helps, here's the entire configuration:
Intel Bad Axe motherboard w/ Oct 25th, 2006 BIOS
Pentium 805 (non-overclocked)
4 GB DDR2 667 RAM
Gigabyte X1300 Silent Card
2 Raptor Hard Drives
Fusion III Gold Q
