One of the advantages of Open mode and ubiboot should be: 'You will not need to flash the device to install and test a new kernel; just copying the kernel and modules to the device is enough.'

I have earlier used this procedure for Open mode: http://forum.nitdroid.com/index.php?topic=241.0
meaning zImage.pr13 but without sillyboot and NITDroid.

Instead I have multiboot from here:
http://talk.maemo.org/showthread.php?t=86957

I have flashed to Open mode in Windows7 therefore /boot is empty (e.g. no zImage here)

Checking my N9 in terminal shows:
~ # export LANGUAGE=C
~ # accli -I
Current mode: open
IMEI: 357923045945013
Credentials:
UID::root
GID::root
GRP::root
GRP::adm
GRP::dialout
GRP:: pulse-access
~ # uname -r
2.6.32.54-dfl61-20121301

Want to change kernel to:
zImage_2.6.32.54-ubiboot-02_040613
Using this procedures:
http://wiki.maemo.org/Ubiboot#Moving...g_Filebox_Root

Download file:
zImage
ubiboot-02_040613.tar

Copy to /home/user/MyDocs/boot:
ubiboot.conf
ubiboot-02.menus.cpio

Copy to /boot (which is empty!):
zImage (changed to zImage_e-yes_nitdroid+12fix)
zImage_2.6.32.54-ubiboot-02_040613

Correct and if then further what to do?
