  • Page 60: Non-Pxe Boot Installation

    Non-PXE Boot Installation When the setup script is run with the “-t” option, it generates a nonpxe.bfb file at the directory where the script is run. The directory contains the install kernel and rootfs which are usually loaded by UEFI during the initial PXE boot stage. Thus, if pushing this file, the host TFTP server no longer needs to be used and UEFI would automatically load the install kernel and rootfs from the boot FIFO.
