21.6.2. Configuring the OS/400 Boot Loader

The /boot/vmlinitrd-kernel-version file is installed when you upgrade the kernel. However, you must use the dd command to configure the system to boot the new kernel.
  1. As root, issue the command cat /proc/iSeries/mf/side to determine the default side (either A, B, or C).
  2. As root, issue the following command, where kernel-version is the version of the new kernel and side is the side from the previous command:
    dd if=/boot/vmlinitrd-kernel-version of=/proc/iSeries/mf/side/vmlinux bs=8k
Begin testing the new kernel by rebooting the computer and watching the messages to ensure that the hardware is detected properly.
