ZBOX-BI320

In the kernel, load *all* the HDMI audio codecs as modules. It'll break otherwise.

Also, the video card drivers (i915) must also be loaded as modules, or the box will segfault on booting.

lsmod output:

For the USB Realtek card reader, here are the device drivers needed:

• MFD_RTSX_USB
• MMC_REALTEK_USB

Once those are properly installed (in-kernel or modules), you'll see /dev/mmcblk0 as your block device, with partitions numbered after that.
