renumbering channels without using a PC

for various reasons too boring to go into, I now have a PC with no serial port, hence my inability to hook up to The Box. I want to renumber the channels so that they match the official published numbers, ie BBC1 on 101 and so on. Can't figure it out on the remote, any help much appreciated.

thanx people,,

Not possible on a Standard Starview/The Box. The new Box Super can do this.
