You MUST have another QNX box running in the network to provide the + root filesystem and the license info to the client. QNX cannot use + e.g. NFS for its root filesystem, as it needs to load a valid license + from a file on the root fs before being able to start TCP/IP. This + would lead to a chicken-and-egg problem. +2. The Net task normally determines the size of its internal tables from + the actual number of licensed nodes. Since this information is not + available at boot time when booting from the network, you will have + to set the max. number of nodes as well as a valid netmap entry for + the node providing the root filesystem as an option to Net in the + build file. + See examples/ws.etherboot and fill in the <blanks>. +3. The client does not need a TCP/IP license in order to boot. +4. You can use the boot-server OS of your choice. If you choose to use + QNX as boot server, the server of course needs a TCP/IP run-time + license. In this case you have the option of creating the boot image + on-the-fly and use the macro $(netmap) instead of a hard-coded MAC + address. + See examples/ws.etherboot.on-the-fly and fill in the <blanks>. + A template bootptab for the QNX bootp server is placed in the + examples directory. +5. mkQNXnbi expects the QNX image to be supplied on stdin and generates + the tagged image to stdout. This can be overridden on the command line + using the options -i <input-file> and -o <output-file>. + +mkQNXnbi can be compiled using e.g. Linux/gcc or on QNX using Watcom C +(or gcc, if you have it - see http://w3c.teaser.fr/~jcmichot/) + +Bug-reports to <al@alarsen.net> + +2002-01-25 +Anders Larsen +<al@alarsen.net> |
