20.6.2. 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.
As root
, issue the command cat /proc/iSeries/mf/side
to determine the default side (either A, B, or C).
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.
