It is possible to use <code>bzImage</code> from a different Slackware version, in this case the directory <code>/lib/modules/X.X.X/</code> must be upgraded to the same version.  This can be useful to support newer hardware.
* Install a Linux distribution that uses grub as boot loader on the remote server
*Unpack initrd image (as root):
* Put <code>bzImage</code> and <code>initrd.img</code> to /boot/rescue/ directory on the remote server
<pre># mkdir dir
# cd dir
# zcat ../initrd.img | cpio -di</pre>
*[[Chroot]] to dir and set a root password; exit chroot
*Add to the file <code>dir/etc/hosts</code> the ip address of a Slackware mirror that will be used for installation (since no nameserver will be accessible)
*Pack the modified initrd image: <code>cd dir; find . | cpio -o -H newc | gzip -9fv > ../initrd.img</code>
*Install a Linux distribution (e.g., Debian) on the remote server
*Put <code>bzImage</code> and <code>initrd.img</code> to /boot/slack/ directory on the remote server
