I was searching all over the net and found a guide:

---------------

Making sure you can still see your card when connected to your PC via USB
If you now connect your device to a PC via USB, you’ll get a message stating “Memory cards in use: internal memory card” and your memory card won’t be available to your PC. To get round this you need to edit /usr/sbin/oss-mmc-umount.sh, replace the if block after the line grep "$MP " /proc/mounts > /dev/null with:

if [ $? = 0 ]; then
if [ "$MP" != "/extfs" ] ; then umount $MP 2> /dev/null ; fi
RC=$?
if [ $RC != 0 ]; then
echo "$0: could not unmount $MP"
exit $RC
fi
fi

Note - if you called your mount point something other than extfs, remember to edit the test [ "$MP" != "/extfs" ] accordingly. Your FAT partition will now be umount’ed before being made available to your PC. The linux partition also be available but will remain mounted in your device. This should be safe as long as you don’t try to write to the ext3 partition, you probably only need to write to the FAT partition anyway.

But unfortunately i doesn't help... So what should I do? Help :) SOS and so on ;)

I tested successfully for my MMC boot which I done a long time back.

I'm not sure if your question is rhetorical.

Such is the life of a dual-booter. As an alternative, you could copy to one of the directories that do show with the USB connection and then move the files in a File Manager.

EDIT: I posted this before seeing qwerty12's much more useful response. :) (I haven't tried the fix myself as I don't find it a problem writing only to my external MMC when connected to my PC; though I can see how someone else may not like it.)

Re: HOW TO: Simplest and Complete Cloning of OS to MMC; Dual-Booting

this might be an ultra noob questions, but what is the benefit of dual booting. do I need to dual boot.

i pretty much just want to install some software... i want to use my n800 (just received it finally yesturday)

I would like Maps (without gps)
Instant messanger
media (movies & songs)
surf the net

thats about it...

should or do i need to dual boot...

Re: HOW TO: Simplest and Complete Cloning of OS to MMC; Dual-Booting

You certainly don't need to. It allows you to put more apps on your NIT. It allows you to do a better (a real) backup or to clone a system and apps to go in another NIT. It allows you to have alternative system-and-app configurations. Some users like to install KDE (which apparently takes a lot more room than I allocated in the guide). It might make your N800 trivially faster. It's pretty esoteric, really, and there is no need to do it at all.

I just wanted to say It Works! And it works great. Incase anyone is reading this and they have an N810, this process will install the Clone OS in the internal 2G flash drive. This is exactly what I was looking for. This increased the amount of space available for programs and it still allows me to change mini SD cards without affecting anything. The removable storage is great for adding/changing pictures, music, videos, etc...

Thanks again GK :)

Re: HOW TO: Simplest and Complete Cloning of OS to MMC; Dual-Booting

Why would there be a problem if you cloned the image to MMC? Shouldn't it also clone all the repos and such? (probably going to buy a 16 GB SDHC soon and do this since 128 MB of memory is really hampering me).

Re: HOW TO: Simplest and Complete Cloning of OS to MMC; Dual-Booting

My 770 will not boot into the flash. Gives a loop and WSOD. I did not set enough space in MMC to install all and how now to get back into Flash?!?

Great tutorial though. I wish I had found it earlier before I borked mine!

Well, you should always be able to get back to your flash boot. (That's why it's called dual-booting! ;) ) After you've pressed the power button, as soon as you see anything happening on the screen, press and hold the menu key until it shows you the boot menu.
