linux-image-2.6.15-21-amd64-k8 2.6.15-21.32 (amd64 binary) in ubuntu dapper

 This package contains the Linux kernel image for version 2.6.15 on AMD
 Athlon64/Athlon FX/Opteron, the corresponding System.map file, and the
 modules built by the packager. It also contains scripts that try to
 ensure that the system is not left in a unbootable state after an update.
 .
 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.
