linux-image-2.6.15-23-amd64-server 2.6.15-23.39 (amd64 binary) in ubuntu dapper

 This package contains the Linux kernel image for version 2.6.15 on
 server equipment, the corresponding System.map file, and the
 modules built by the packager.
 .
 If you wish to update a bootdisk, or to use a bootloader to make
 installing and using the image easier, we suggest you install the latest
 fdutils (for formatting a floppy to be used as boot disk), and LILO, for
 a powerful bootloader. Of course, both these are optional.
 .
 Kernel image packages are generally produced using kernel-package, and it
 is suggested that you install that package if you wish to create a custom
 kernel from the sources.
