I will try, thanks!
I find the sound is also malfunctioning, it shows in Windows XP and rivers are correct, but there is no output.

What is your configuration exactly? CPU, GPU, PSU and so on.
Have you tried on the table?

Mobile 2500+, 1GB DDR400, X850XT. I will try to update the BIOS once more.
It's on the table currently.

Quick uprate: SATA started working suddenly, but there was still no sound.
