Ok, I can do that.

It is detected by the kernel ok, but I have not used it yet.

Yes there is an onboard CF slot. It is connected to the primary IDE  
controller. I did use a CF-to-IDE adapter, and that works fine.

The IR is for the wireless keyboard, connected to COM2, as long as  
COM2 is enabled it works fine. I have not tested it with lirc and a  
remote yet.

Even if there is no PC Speaker onboard? Would the beeping happen on  
the audio out?

I agree but I have not tested it yet. It is enabled in the nics eeprom

Do you want me to send it to the list, or post it on the wiki??
