gPXE currently overwrites the filename stored in the cached DHCP packets when a call to PXENV_TFTP_READ_FILE or PXENV_RESTART_TFTP is made. This code has existed for many years as a workaround for RIS, which seemed to require that this be done. pxe_set_cached_filename() causes problems with the Bootix NBP, and a recent test demonstrates that RIS will complete successfully even with pxe_set_cached_filename() removed. There have been many changes to the DHCP and PXE logic since this code was first added, and it is quite plausible that it was masking a bug that no longer exists.

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.
