The second partition is 1.6GB ext2. Here is where my maemo-mapper maps are stored along with a few videos and such.
The remaining 128MB or so is formated as linux swap.

Now, in order to use this setup, you need to edit a few files as root so make sure you can become root and get a # prompt. Also you'll need an editor that you know how to use. I like the built-in vi editor or the vim application but I've been using vi for 20 years. It's not the easiest editor to learn. Midnight Commander (mc) is a cool console file manager that has an editor and I think there's a leafpad for OS2006.

The first thing we'll do is tell the 770 how to mount the partitions by adding a few lines to /etc/fstab. Open xterm (or ssh in from your PC) and "switch user" (su) to root by typing

Code:

sudo su -

note the space and dash after su.
Your prompt should end in ~# If not, you're not root. fix this before continuing.

Open /etc/fstab in your editor of choice and add the folowing 2 lines:

Code:

/dev/mmcblk0p2  /media/mmc2 ext2 rw,noauto      0 0
/dev/mmcblk0p3  swap    swap    defaults        0 0

Next we want to load the ext2 kernel module and mount the ext2 partition and activate the swap partition. Open /etc/init.d/minircS in your editor. near the top, right after the PATH= line add this line:

Code:

insmod /mnt/initfs/lib/modules/2.6.16-omap1/ext2.ko

Then at the end of the file, just before the exit 0 line, add:

Code:

swapon -a
mount /media/mmc2

Now to be nice, we want to unmount mmc2 and de-activate the swap when re-booting or shutting down so edit both /etc/init.d/minireboot and /etc/init.d/minishutdown. Find the line that starts: umount -r and add /media/mmc2 to that line and add swapoff -a so it looks like this:

Code:

echo "Unmounting filesystems... "
umount -r /media/mmc1 /media/mmc2 /mnt/initfs /
swapoff -a
echo "done."

reboot and that's it. You now have a 128MB swap, a big FAT32 partition at /media/mmc1 and a nice big ext2 partition at /media/mmc2.
