- gPXE Image types: explanation on types of images cranked out by make or r-o-m
Many parts of the gPXE code-base include commenting for use with the Doxygen system. To build this documentation for browsing, go into gPXE src/ directory and do
You will then have the documentation available in your gpxe/src/bin/doc/ directory.
A sample build is available here.
- Introduction: A typical network boot scenario, including explanations for new users
Network Bootable Image format (NBI) is a legacy format that wraps operating system images (such as Linux kernels) in a wrapper, which makes it possible for Etherboot to load the images directly. The “mknbi” (make NBI) utility performs the wrapping operation.
Unfortunately, mknbi cannot be used to make a NBI of a Linux 2.6 (or newer) kernel image. If you are tied to Etherboot but need to boot a Linux 2.6 or newer kernel, wraplinux must be used to create a working NBI. Follow the link to wraplinux on kernel.org to download it.
Note: This is not needed for PXE and PXELINUX booting, and is not recommended for new users. For new users, we recommend using PXELINUX
For those who need to use the NBI format, please see:
