thanks, will check bios if there is something.
Actually, right after I installed the card, there was a small icon in menu bar. It didn't function then as expected, so I tried the option "power off card" in the menu, and after that it was no longer visible.
After that, I changed the PCI slot to see if I could get the menu bar icon back but no luck.
Anyway, thanks!
best,
