Hi! I am a rookie in this community and I'm not a linux expert. However I am glad to give you my help. Step By step boot video change for N900: 1- go to the repository menu of N900 2- Install ssh server on N900 3- ssh on installation will ask you for a password (choose one) 4- go to your main PC and download a free ssh client with a graphic interface (it's much easier to use for a newbie) like winscp. 5- in your N900 launch xterminal and type: sudo gainroot 6- in x terminal type then: ifconfig 7- ifconfig will show you r ip address (of course you MUST be connected to a wireless lan with your N900 ) 8- open winscp and login to this ip address. login:root password: your passord 9- go tho /usr/share/hildon-welcom/media and copy the boot video you want. 10- ho to /etc/hildon-welcom.d/ and copy default.conf to ypur PC 11-open in your PC default.conf with notepad and modify it with the name of the new video 12- save without changing name of the file 13- replace the file .conf in N900 14- disconnect and restart N900. That's it... I hope to have been useful Corto Maltese
