Yeah, there is a COM1 connector and I've attached a serial port brace to have
the connector on the back of the board.

BIOS says:
Serial(COM) Port 0 Configuration
Port Enabled
Settings IO=3F8H, IRQ=4
It was on "Auto" before but neither setting changed anything.
I don't know how relevant this is about that same PCI device:
pnp 00:06: [dma 0 disabled]
I'll try to upgrade the BIOS, maybe it really is an ACPI f*ckup.
Thx!
