This directory contains precompiled Linux kernels.  Brief descriptions of
each kernel is given below.  You can find complete descriptions of the
kernels in the individual "config" files in each kernel subdirectory.


   javastation.n   Sun JavaStation "Mr. Coffee" and "Krups"  support.  There are
                   no IDE or SCSI drivers in this kernel, as the Javastation has
                   no provisions for those.  This kernel is also set up
                   with proper network booting and root filesystem support.
                   Systems that should use this image:

                      Sun JavaStations 

   sun4.s          Not available -  Sun 4 systems are no longer supported.

                   SCSI disk and CD-ROM support and all available SPARC SCSI
                   drivers.  NOTE:  This kernel can also boot sun4m and
                   sun4d machines, but does not support SMP machines in those
                   families.

   sun4d.s        Support for the sun4d family of SPARC systems.
                   Contains SCSI disk and CD-ROM support and all available
                   SPARC SCSI drivers. Single processor only. 
                   Use this kernel until we get the SMP bugs fixed.  
                   Systems that should use this image:

                   Contains SCSI disk and CD-ROM support and all available
                   SPARC SCSI drivers. SMP on these machines is UNSTABLE. 
                   Use this kernel ONLY if you want to help fix the kernel bugs
                   and read the latest information at http://www.splack.org/

These kernels are offered for installation during the setup program and they
are provided here as a reference for those wanting to rebuild their kernel.

These kernels are also perfectly fine to add to your system.  Installation
is easy.  Suppose you want to install the sun4u.s kernel.  First pick a
kernel version - 2.4.27 - then have a look at what's in that directory.

  Say it contains these items:

   modules/
   System.map
   config
   vmlinux*

The "modules" directory contains kernel modules specific to the sun4u.s
kernel.  Copy the contents of directory to /lib/modules/2.4.27.
If you previously had a /lib/modules/2.4.27 directory, make sure it's empty
before copying over the new one.

   rm -rf /lib/modules/2.4.27
   mkdir /lib/modules/2.4.27
   cp -av modules/* /lib/modules/2.4.27

The "System.map" and "config" file should be placed in /boot for reference
purposes.  The System.map file is useful for kernel developers and the config
file is the kernel configuration file used to build the sun4u.s kernel.  If
you decide to recompile your kernel, you may wish to start with this config
as a default.  Having it in /boot makes a nice reference.

   cp -a System.map config /boot

The last file is the actual kernel.  Copy it to / and reboot.

   cp -a vmlinux /vmlinux

That's it.  Be careful not to install a kernel that will render the system
unbootable.
