i recently got a n810 so i'm fairly new to it. so hopefully i get my wording correct here and my question kinda makes sense.

1. so here is what i did. i set up a dual boot of diablo. with diablo installed on internal flash, i cloned diablo to my external 4gb card (mmc1). both flash and mmc1 boot well.

2. i wanted to put chinook back on flash for a backup OS or if i decided to ditch diablo

3. so i reflashed my n810 with chinook
# sudo ./flasher-3.0 -F RX-44_2008SE_2.2007.51-3_PR_COMBINED_MR0_ARM.bin -f -R

4. rebooted the tablet and it booted directly into flash (as expected) and chinook works perfectly

5. ran fanoush's initfs_flasher with my custom bootmenu.conf

6. rebooted tablet and boot menu appears and can boot into both chinook (flash) and diablo (mmc1)

7. when i updated diablo from from 4.2008.23-14 to 4.2008.30-2 i notice OS2008 feature upgrade updates:
initfs-flasher (0.95.16-200829maemo1)
kernel-diablo-flasher (2.6.21-200829maemo1)
flash-and-reboot (3)

so i figure it will wipe my boot menu, etc and will only be able to boot to flash, won't be able to boot to mmc1. i figure no bid deal, just rerun initfs_flasher.

*8. here is where i start to run into problems. after OS2008 feature upgrades finish installing my n810 restarts and gets to the initial nokia start screen and just hangs there. i have to take the battery out to get it to shut off. it will not boot at all. not even to flash.

9. so i reflash my n810 with chinook and once again i can boot into diablo after rerunning fanoush's initfs_flasher

i know that the kernel, initfs, etc are updated in diablo. but with chinook on flash and diablo on my external card diablo works, but diablo shows that it is running chinooks kernel and initfs (under control panel as well as xterm # uname -rsv) and every time i install the OS2008 feature upgrades my NIT won't boot because it changes the initfs, etc. so i have to reflash chinook on flash then rerun fanoush's initfs_flasher.

here is where i need some help. how can i get diablo to boot it's updated initfs and kernel when chinook is installed on flash?

is there a way to get/keep chinook's initfs and kernel when booting chinook from internal flash and also be able to boot diablo on my external card booting diablo's updated initfs and kernel?

TIA
