[Freegis-list] need your help, how to set up save your own database in GIS KNOPPIX CD?

[=?gb2312?B?uLUgwek=?=]

hi, all
I have some problem with using GIS-KNOPPIX.
I try to creat a new Location, a new mapset and a new database of my own 
with GIS-Knoppix.
I can creat the new Location and a new mapset follow the tutorial. the path 
where the new location is: /var/lib/grassdata/ 
But the problem is when I shut down and restart the live CD, my location 
and mapset disappeared.

so how I can save my project?

another question:I have the orthophoto, shp.shx.and dbf. format data.
Shall I put them in the subdirectory of Mapset?
The problem is the system always remind me that the file is not available.

Really need your help. If you know the answer, pls kindly tell me.

Best Regard,
Lynn
