Using the "mknbi" Utility with Etherboot

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.

NBI, Etherboot and Linux 2.6

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 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:
