MSCS and Kernel patches: Can someone please refresh my memory?

Question

Greetings,
We run 4.7 Ent on a 2-node MSCS Cluster (SQL).
I need to do a kernel upgrade, but I have forgotten the precise distribution of kernel files outside of the "run" directory for the cluster.
I understand they are:
Main Kernel Files
shared_drive \usr\sap\<SID>\SYS\exe\run
MSCS Files (on each node)
local_drive \Windows\SapCluster\
local_drive \Windows\System32\
However, could someone please remind me which files go into
"SapCluster" and "System32", or if you know the location, point me to an SAP document that details the kernel patch process in an MSCS Cluster (rather than a general MSCS config document which is of no use in this situatio).
Thanks if anyone is able to help.

Hi Tim,
We have a productive SAP R/3 4.7 (Windows 2003 IA64 Oracle 9.2) on a 2 nodes MSCS cluster.
In C:\windows\SapCluster
We have the following files :
backint.exe
brarchive.exe
brbackup.exe
brconnect.exe
brgui
brrecover.exe
brrestore.exe
brspace.exe
brtools.exe
cpio.exe
cpqccms.dll
dd.exe
dev_rout
mkszip.exe
mt.exe
niping.exe
pstat.exe
rfcoscol.exe
routtab.txt
sapevents.dll
sapgw
sapntchk.exe
sapntwaitforhalt.exe
saposcol.exe
saprouter.exe
sapsrvkill.exe
sapstart.exe
sapstartsrv.exe
sapstartsrv.exe.new
sapxpg.exe
uncompress.exe
So basically the SAP cluster dlls and the brtools.
We have also  C:\windows\SapCluster\brgui with the brgui files
and C:\windows\SapCluster\sapgw with the standalone gateway executables
In C:\windows\system32 we have these SAP files :
sapmmc.dll
sapmmcada.dll
sapmmcinf.dll
sapmmcms.dll
saprc.dll
saprcex.dll
sapstart.log
sapstartsrv.exe
To update the kernel, we do it one node after the other one switching the SAP resources between the 2 nodes .
We of course keep the same patch level in the different directories.
Hope this helps.
