i tried an stec 16gb in all the slots, wifi and wlan. i hear there is no way because there is no ide channel on the wireless slots. but i was thinking that you can install a runcore ssd
and use the usb pins on the wlan socket. especially if your system does not have the wlan connector, you can solder the 4 pads where the conector goes that corespond to the usb bus to the usb cable for a runcore. i dont remember the pin numbers for the usb channel but they are available in other threads on this forum. i was actually considering this option until i decided to just buy a western digital passport external drive on sale.
