is my source.list file out of date.......

Dear Folks,

My source.list file looks like this:

#
# deb cdrom:[Debian GNU/Linux 5.0.7 _Lenny_ - Official amd64 NETINST
Binary-1 20101128-00:59]/ lenny main

#deb cdrom:[Debian GNU/Linux 5.0.7 _Lenny_ - Official amd64 NETINST
Binary-1 20101128-00:59]/ lenny main

deb http://ftp.uk.debian.org/debian/ squeeze main contrib non-free
deb-src http://ftp.uk.debian.org/debian/ squeeze main

deb http://security.debian.org/ squeeze/updates main
#deb-src http://security.debian.org/ lenny/updates main

deb http://volatile.debian.org/debian-volatile squeeze/volatile main
deb-src http://volatile.debian.org/debian-volatile squeeze/volatile main

Is the debian-volatile repository redundant now?   If it is would I
just delete it or could I put something else in there.

I am running Debian Squeeze on an AMD 64 machine.

I recently took the hard drive out of the old AMD64 box and stuck in a
new box with a newer motherboard in it.    The OS still runs but I
probably freaked it a bit.  Firestarter seems not to work now.

Suggestions on getting it used to what I did welcome.

The new motherboard is a GA-A55M-S2V model and an AMD A 3400 chip.

Regards

Michael Fothergill
