I just got N810 after 2 years of using N770 and couldn't be happier. Yesterday got 8GB SD card and decided to set up dual boot using 2GB internal SD as a second bootable partition. I used instructions in the KDE thread but did a slight variation of these as I did not want to partition internal SD and instead made it one ext2 partition. I had to make a slight change in bootmenu.sh so it is loading from the right partition, and it now boots from 2Gb SD, but my 8GB external card is not mounted at all.
When I boot from flash I get:
/dev/mmcblk0p1 on /media/mmc2 type ext2
/dev/mmcblk1p1 on /media/mmc1 type vfat
When I boot from SD I get:
/dev/mmcblk0p1 on /media/mmc2 type ext2
/dev/mmcblk1p1 on / type ext2
All attempts to mount external SD manually were unsuccessful. I realize that most likely I need to make some changes in bootmenu.sh and re-flash, but for the life of me cannot figure out what - shell scripting is not my forte...

Please help!

TIA
