[Arm-netbook] ARM HDA Advice?

[Valery Yundin]

Hi,

I used cnxsoft's SD card image as a starting point.
Then copied root partition to USB HDD and changed bootloader options, e.g.
root=/dev/sda2

So the kernel is booted from SD card first partition /dev/mmcblk0p1
and it mounts rootfs on USB disk

I also compiled my own kernel, but that is mainly because I needed JFS
support. You can compile a kernel on Mele using cnxsoft scripts.
