 # Installation
 
+## SD card structure
+
+The Raspberry Pi looks for firmware and a kernel on the first FAT32
+partition of the uSD card.  The NetBSD kernel will then use the FFS
+partition as the root filesystem.
+
+A 2 GB card is the smallest workable size.  The NetBSD filesystem will
+be expanded to fit on larger cards.
+
+## Choosing a version
+
 First, decide if you want to install a formal release (7.1), a stable
 branch build (netbsd-7, netbsd-8), or current.  Note that 7.1 predates
 Raspberry Pi 3 support.  For people who don't know how to choose among

 ### Serial Console
 
 By default the rpi.img is set to use the HDMI output.  If you wish to use a serial console, first mount the FAT32 partition and then
 edit cmdline.txt and remove '"console=fb"'.

 ### Installation with sshramdisk image
 
 build.sh (and hence the FTP site) also creates an image 'rpi_inst.img.gz' specifically for installation without HDMI or a serial console.  To use this method, write that image to a uSD card as above, and then:

  - After starting DHCP client, SSH login to with user "sysinst", and password "netbsd".
    - Be careful to note the ip address given during DHCP so you don't lose your connection
    - Also for after the sysinst is done and the system reboots
