I have found a lot of answers on this excellent forum, but need one more.

I am trying to either extend the root file system of my 770 to my RS-MMC card or to boot from it. I have done this successfully in the past. I am using 2007 HE Mk II, as I did in the past.

I have partitioned and formatted my 2gb card into a VFAT, an EXT3, another EXT3, and a final VFAT partition. I also tried VFAT, EXT2, EXT2, + VFAT. But no matter what I try, I can only mount the first and fourth partitions. I partitioned with sfdisk from the 770 (it is the only partitioner I can find). I formatted the linux partitions with mke2fs.

I have even manually added the necessary entries to /etc/fstab. But they do not change the fact that the system does not recognize /dev/mmcblk0p2 and /dev/mmcblk0p3 as valid devices when I go to mount. Also, the fstab file does not retain my changes after a reboot (I guess becuase it is read only). I made the change with echo -e "...">>/etc/fstab.

What I find very confusing, is if the system does not recognize the 2nd and 3rd partitions, why does it recognize the 4th partition as /dev/mmcblk0p4 and not as /dev/mmcblk0p2? And why can I format the partitions without incident if they are not valid?

I have read hundreds of posts, how-to's, and manual pages and am getting very frustrated.

Help!
