mkQNXnbi is a quick hack to generate tagged images from QNX boot images.
|
||
|
|
|
||
|
|
To boot a QNX client with Etherboot you have to consider the following:
|
||
|
|
1. 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/)
