That looks about right. I'd be interested to know what the BIOS can see, ie before Grub has loaded. I would predict you can see the USB but not the MMC/SD card slot. (Note that you will probably need to insert something in them to stand _any_ chance of seeing any of them.) BTW did you notice that the webpage gave the battery life as 7.8 sec! Cheers, David.
