- They are routinely reloaded with different software from onboard storage
- (tape, I think), but I don't think there is any remote-upload capability.
- In an emergency, the astronauts can input patches manually -- NASA insisted

- having the patch routine pop up a little flag saying "your warranty is void"
- when it was used :-)) -- but that's not suitable for routine use.
