xCAT Network Boot Agent
f866b17998
During development it is often handy to change the config.h options from their defaults, for example to enable debugging features. To prevent accidental commits of debugging config.h changes, mdc suggested having a config-local.h that is excluded from source control. This file acts as a temporary config.h and can override any of the defaults. This commit is an attempt to implement the config-local.h feature. The config.h file now has the following as its last line: /* @TRYSOURCE config-local.h */ The @TRYSOURCE directive causes config-local.h to be included at that point in the file. If config-local.h does not exist, no error will be printed and parsing will continue as normal. Therefore, mkconfig.pl is "trying" to "source" config-local.h. |

gPXE README File gPXE is an implementation of the PXE specification for network booting, with extensions to allow additional features such as booting via HTTP, iSCSI, and AoE. In generally, gPXE is compatible with the industry-standard PXE specification, and also supports Etherboot .nbi file loading and some additional protocols and features. For more detailed information about gPXE, please visit our project website at: http://etherboot.org/ BUILDING gPXE IMAGE FROM SOURCE If you don't want to install development tools, and have access to the Web, you can get gPXE and Etherboot ROM images made on demand from http://rom-o-matic.net/ If you would like to compile gPXE images from source, here are some tips. We normally compile gPXE images on x86, 32-bit Linux machines. It is possible to also use x86-64 machines. We use gcc compiler options to create 32-bit output. It is important to have the necessary software packages installed. A gcc-based toolchain is required. The following packages (at least) are required: - a gcc tool chain (gcc 3.x or gcc 4.x) - binutils - perl - syslinux - mtools To test your environment, cd to the "src" directory and type: make You should see a lot of output, and when it stops, the "bin" directory should be populated with gPXE images and object files. To learn more about what to build and how to use gPXE, please visit our project website at http://etherboot.org/ , particularly the "howto" section. CONTACTING US Pointers to our project mailing lists are on http://etherboot.org/ Real-time help is often available on IRC on the #etherboot channel of irc.freenode.net.
