kernel directory contains unpackaged kernels. If you want a *tested* kernel-image.deb package, check the debian mirror nearest you. Kernels here are not guaranteed to work for everyone. 32, 32-smp, 64 and 64-smp directories contain default kernel builds. Model specific directories contain kernels, firmware update images, and other machine specific configuration files that the maintainers found useful for setting up the box. *.tar.gz files contain a kernel plus compressed Config and System.map files like this: -rw-r--r-- bame/ses 4292877 2001-11-18 16:40:14 vmlinux-64-2.4.14-pa6 -rw-r--r-- bame/ses 132609 2001-11-18 16:40:17 System.map-64-2.4.14-pa6.gz -rw-r--r-- bame/ses 3787 2001-11-18 16:40:17 Config-64-2.4.14-pa6.gz Move the files to /boot, modify /etc/palo.conf to use them, run palo, then reboot. Don't remove old kernels until you are confident things work better overall than before. The matching config file is really only useful should someone care to rebuild their own kernels. They aren't needed for booting or normal operation.
