-.Boot over IB over Mellanox HCAs README - Pre-Alpha release
-==========================================================
-Document #2442, Rev 0.10, December 2005
-
-
-1. General
------------
-This README describes the Boot over IB package which enables booting a Linux 
-kernel from a remote server using one of the Mellanox Technologies HCA 
-devices. The package is based on Etherboot 5.4.1.
-
-The package actually implements a network driver for Etherboot. The wire 
-protocol is compliant with IP Over IB 
-(see http://www.ietf.org/html.charters/ipoib-charter.html for related 
-documents).
-
-Etherboot uses a traditional setup of a DHCP server and a TFTP server to 
-perform a remote boot in a similar manner to Ethernet NICs. The binary code is 
-exported by the device as an expansion ROM image.
-
-
-2. Supported Devices
----------------------
-The following Mellanox Technologies HCA devices are supported:
-
-	PCI Device ID		Mellanox HCA Device
-	----------------------------------------------
-	23108			InfiniHost (P/N MT23108)
-	25208			InfiniHost III Ex (P/N MT25208) (InfiniHost)
-	25218			InfiniHost III Ex (P/N MT25208) (MemFree)
-	25204			InfiniHost III Lx (P/N MT25204)
-
-	
-	Note:	For devices with more than one IB port, port 1 is used for 
-	communications.
-
-
-3. Compiling
-----------------
-From the src directory:
-Run" make bin/<device>.<ext>
-where device can be any of:
-	MT23108
-	MT25218
-	MT25208
-	MT25204
-	
-and ext can be rom, zrom etc. (see Etherbot doumentation for more details)
-
-4. Directory Structure
------------------------
-All driver files are available under src/drivers/net/mlx_ipoib/. Under this 
-directory the following files can be found:
-	
-	*** 	doc - Contains related documents including this file.
-	***		patches - Contains needed patch files.
-	*** 	samples - Contains sample files.
-	*** 	. Contains driver source files.
-	
-
-5. Burning the Flash Memory
-----------------------------
-The binary code resides in the same Flash device of the device firmware. 
-However the binary files are distinct and do not affect each other. Mellanox's 
-'mlxburn' tool is available for burning, however, it is not possible to burn 
-the expansion ROM image by itself; rather, both the firmware and expansion ROM 
-images must be burnt simultaneously.
-
-'mlxburn' is part of the Mellanox Firmware Tools (MFT) package 	available for 
-download from www.mellanox.com under 'Firmware Downloads'.
-
-Example:
-The following command burns a firmware image and an expansion ROM image to an 
-InfiniHost Adapter Card (P/N MHX-CE128-T.ini):
-	  
-   mlxburn -fw fw-23108-a1-rel.mlx -exp_rom MT23108.bin
-			 /dev/mst/mt23108_pci_cr0 -conf MHX-CE128-T.ini
-
-*** Important Note: The .ini file must support burning expansion ROMs. For 
-example, the following lines must appear in the .ini file. If they do not, 
-please add them	manually.
-
-[ADAPTER]
-exp_rom_en = true
-
-Mellanox's web site contains firmware binary files with extension .bin.gz. 
-These files contain contain EVERYTHING the goes in the flash memory and thus 
-are NOT suitable for including the expansion rom image. Therefore, one use the 
-files with .mlx extension also available from Mellanox's web site.
-
-	
-
-6. Preparing the DHCP Server
------------------------------
-DHCP messages over IP Over IB are transmitted as broadcasts. In order to 
-distinguish between messages belonging to a certain DHCP session, the messages 
-must carry the client identifier option (see ietf documentation	referred to 
-above). As of November 2005, ISC DHCP servers do not support this feature. 
-They are expected to support this at the end of 2005. In order to work this 
-out, the appropriate patch must be applied (see patches directory). It has 
-been tested on version isc-dhcpd-V3.0.4b2.
-
-The DHCP server must run on a machine which supports IP Over IB. The Mellanox 
-IBGD package (gen1 or gen2) can be used to provide this.
-To run the DHCP server from the command line use: dhcpd ib0
-
-7. DHCP Server Configuration File
-----------------------------------
-In order for the DHCP server to provide configuration records for clients, an 
-appropriate configuration file dhcpd.conf must be created and put under /etc/. 
-A sample configuration file with comments can be found in the samples directory.
-
-
-8. OpenSM
-----------
-To successfully boot over IB, the IB network must contain a Subnet Manager 
-which configures the IB network. OpenSM is part of the IBGD distribution and 
-can be used to accomplish that. Note that OpenSM may be run on the same host 
-running the DHCP server but it is not mandatory.
-
-
-9. TFTP Server
----------------
-When the DHCP session is completed, the client has the IP address of the TFTP 
-server from which it should download the kernel image. This TFTP server must 
-run on a machine with InfiniBand support. The client loads first a loader 
-image based on PXE API which then loads the kernel image. The image can be 
-found in the Linux kernel homepage:
-
-http://www.kernel.org/pub/linux/boot/syslinux/
-
-
-10. BIOS Configuration
------------------------
-The expansion ROM image presents itself to the BIOS as a boot device. As a 
-result, the BIOS will add it to the list of boot devices. The priority of this 
-list can be modified when entering the BIOS setup. The boot over IB	image must 
-be set first for the BIOS to attempt to use it first.
-
-
-11. Operation
---------------
-When booting the client, a message appears on the screen describing the device 
-found and the revision of the code. The user has 3 seconds to press a key for 
-increased functionality:
-'V' will increase verbosity.
-'I' will prinit some information to aid in configuring the DHCP configuration 
-    file. In this case the display will hold for 5 seconds to let the user 
-	grasp the information.
-	
-Note that increasing verbosity will significantly slow boot time and will 
-print lots of debug messages to the screen.
-
-
-12. Diskless Machines
-----------------------
-Most often it is required to boot a diskless machine. In these 	cases the 
-kernel mounts its root file system over NFS over one of the interfaces. For 
-this to happen on a client with only InfiniBand interfaces, the kernel image 
-must be configured accordingly and must include IP Over IB support. This can 
-be achieved either by compiling this into the kernel or using initrd images 
-that contain IP Over IB support.
-
-
-13. Changing Defaults
-----------------------
-As stated the driver uses port 1 for its communications. To use another port 
-edit the file src/drivers/net/ib_driver.h and modify the definition of 
-PXE_IB_PORT.
-
-
-14. Installing a package from Mellanox
---------------------------------------
-When using a package obtained from Mellanox Technologies' web site, the
-directory src/bin will contain the driver binary files. The files have a .bin
-extension and are equivalent to the same files with .zrom extension.
