Hi,
I did the same on my TS7260 some weeks back. Check out:
http://tech.groups.yahoo.com/group/ts-7000/message/5312
It might be close enough if you get the correct files from the FTP site.
I don't think adding a SD card socket will help unless you have the
PLD updated to drive it, and in any case, the code you ran is, I
suspect, for the SD card driver update for the TS7400 and won't work
properly on your TS7250.
hope you get it going
