Boot data
To boot Linux®, you generally need a kernel image, boot loader code, kernel parameters, and an initial RAM disk image.
For sequential I/O boot devices, z/VM® reader and tape, the order in which this data is provided is significant. For random access devices, there is no required order.
On Red Hat® Enterprise Linux
9.2, kernel images are installed into the
/boot directory and are named vmlinuz-<version>.s390x.
For information about where to find the images and how to start an installation, see the Red Hat
documentation website
