[cobalt-users] Raq550: uninstall and reinstall Kernel C12?

["JMG Enterprises Support" <JMG-Support@xxxxxxxxxxxxxxxxxxx>]

Hey group, 

I have a problem that I can really use some help.  Basically, I need to
either reinstall C12 Kernel correctly or remove so I can install it
correctly.  I am trying to avoid reformatting, reloading, etc....

SOME HISTORY ON THIS UNIT:
This is a real Raq550, 1.26 Mhz, 1.0 GB Ram, 2x80 GB hard Drive.

Previously, this unit had that reboot probem after Kernel C10.  I ran the
following fix as found in the archives at the time and it helped stop the
rebooting.  It forced the install of the RPM for Kernel C12.
=======
cd /tmp
wget
ftp://ftp.cobalt.sun.com/pub/products/raq550/RPMS/kernel-2.4.16C12_V-1.i386.
rpm
wget
ftp://ftp.cobalt.sun.com/pub/products/raq550/RPMS/kernel-headers-2.4.16C12_V
-1.i386.rpm
wget
ftp://ftp.cobalt.sun.com/pub/products/raq550/RPMS/bwmgmt-1.0.0_2.4.16C12_V-1
.i386.rpm
rpm --install --force kernel-2.4.16C12_V-1.i386.rpm
rpm --install --force kernel-headers-2.4.16C12_V-1.i386.rpm
rpm --install --force bwmgmt-1.0.0_2.4.16C12_V-1.i386.rpm
/sbin/reboot
=======
After it rebooted, It has also taken all of the updates since then except
the new pkg for the C12 kernel and the C13 Kernel.

I did try to remove the kernels using the solution below from Michael
Stauber (March 2 post):
    rpm -qa|grep bwmgmt
    rpm -e --justdb bwmgmt-1.0.0_2.4.19C9_V-1
    rpm -e --justdb bwmgmt-1.0.0_2.4.19C10_V-1
    rpm -e --justdb bwmgmt-1.0.0_2.4.16C12_V-1
    rpm --rebuilddb

But again the packages would not Re-install.  The GUI in BlueLinQ still
shows Kernel C10 intalled and does not list C9 (I assume it removed the
reference).  Kernels C12 and C13 are still listed as packages to be
installed but they do not.
Here are the results of each install from the GUI (using Manual install
option and the pkg URL from Sun).

 - Kernel C9 :  The GUI reponded with "this package is no longer current".
 - Kernel C10:  The GUI responded as already installed
 - Kernel C12:  The GUI goes to 100% but never reboots.  The pkg remains in
the BluelinQ list.  Kernel C10 is still listed in the GUI as the only Kernel
installed.
 - Kernel C13:  The GUI says it needs C12 First (this is expected).


MY QUESTIONS:

1) Do you know how to uninstall the C12 version that we installed above so I
can install the BlueLinQ pkg Version?

2) Is there a way to force the reinstall of these Kernels?

3) What is the difference between the i386 version and the versions without
the i386?

4) Maybe the flag that the GUI is detecting to keep it from installing
either can be removed?

Any help that you can provide will be appreciated.
