-----
+This article describes the steps required to re-install IRLP and Debian onto a
+Raspberry Pi computer from an existing IRLP node.
+If you would like a ready-built and configured system, consider ordering one
+direct from IRLP at http://irlp.net/order.html they also have prefabricated
+and all necessary parts to complete your PiRLP project.

+====Prerequisites and Disclaimer====
 First thing, back up your existing install using the "backup_for_reinstall"
 script. It will create an irlp_backup.tgz file on a USB stick - More on this
 later.

+IRLP will try to help where I can, but can not promise it will all work. If you
+are not able to troubleshoot the problem on your own, consider ordering a complete

-Hardware required:
+====Hardware Required====
-- IRLP Ver 3.0 board
+You will require the following hardware:
-- Raspberry Pi Model B (any Revision SHOULD work, tested on a Rev 2)
+  * IRLP Ver 3.0 board
-- DB-25 to IDC 26 parallel cable (or similar)
+  * Raspberry Pi Model B, B+, or Pi2
-- USB sound card (most all should work, I am using the one listed below)
+  * A **suitable** power supply. Please see [[powering_your_pi|Powering your Pi]]
-- 2G (min) SD card (larger is better, but not required)
+  * DB-25 to IDC 26 parallel cable (or similar)
-- USB keyboard (for initial boot only)
+  * Compatible USB sound card. Please see [[compatible_usb_sound_cards|IRLP Compatible USB Sound Cards]]
+  * 2G (min) SD card (larger is better, but not required)
+  * USB keyboard (for initial boot only)
+  * HDMI capable monitor, or an HDMI adapter to another style of monitor
-USB sound card I use is a Syba SD-CM-UAUD, based on Cmedia CM119.
+====Required USB Sound Card====
-Some Pics of the sound card:
+The Raspberry Pi lacks a sound input device. Because of this, a USB sound card must be used. The

-Modifications required:
+Please see the list of [[compatible_usb_sound_cards|IRLP Compatible USB Sound Cards]]
-- Please prepare the IRLP board/parallel cable as shown at:

+Be warned, there is a similar looking sound card on the market that is made
+by Syba that will NOT work. It is the Syba SD-AUD20066. The difference is the
+translucency of the case.

+The following hardware modifications are required:
+- Please prepare the IRLP board/parallel cable as shown at: http://www.irlp.net/R_Pi/
+A schematic of the cable can be found at this link: [[http://wiki.irlp.net/lib/exe/fetch.php?media=raspberrypi_to_irlp_interface_schematic.pdf]]

+If you are using a Pi2 or Pi B+ with a 40 pin header, you must cut pins 27 and 28 from the board in order to  fit the GPIO cable on.
+See: [[http://www.irlp.net/R_Pi/P2010014.JPG]]
+It also shows pin 4 removed - this is not required. It is used as a key for systems ordered from IRLP.
