These images are provided in two variants + - one for downloading the software packages over the network + (available at &armmp-netboot-sd-img;) and one for offline + installations using a Debian CD/DVD (available at + &armmp-hd-media-sd-img;). To save space and network bandwidth, the + images consist of two parts - a system-dependent part named + <quote>firmware.<system-type>.img.gz</quote>, and a + system-independent part named <quote>partition.img.gz</quote>. + </para> + <para> + To create a complete image from the two parts on Linux systems, you + can use zcat as follows: + + <informalexample><screen>zcat firmware.<system-type>.img.gz partition.img.gz > complete_image.img</screen></informalexample> + + On Windows systems, you have to first decompress the two parts + separately, which can be done e.g. by using 7-Zip, and then + concatenate the decompressed parts together by running the command + + <informalexample><screen>copy /b firmware.<system-type>.img + partition.img complete_image.img</screen></informalexample> + + in a Windows CMD.exe window. + </para> + <para> + Write the resulting image onto an SD card, e.g. by running the + following command on a Linux system: + + <informalexample><screen>cat complete_image.img > /dev/SD_CARD_DEVICE</screen></informalexample> + + After plugging the SD card into the target system and powering the + system up, the installer is loaded from the SD card. If you use the + hd-media variant for offline installations, you must provide the + installer with access to the first &debian; CD/DVD on a separate + medium, which can e.g. be a CD/DVD ISO image on a USB stick. + </para> + <para> + When you come to the partitioning step in the installer (see <xref + linkend="di-partition"/>), you can delete or replace any previous + partitions on the card. Once the installer is started, it runs + completely in the system's main memory and does not need to access the + SD card anymore, so you can use the full card for installing &debian;. + The easiest way to create a proper partition layout on the SD card is + to let the installer automatically create one for you (see + <xref linkend="partman-auto"/>). + </para> + </sect2> + <!-- # None of the arm systems supported in Jessie is able to boot from # CD/DVD -> commenting out the "Booting from CD-ROM section" for arm |
