[ubuntu-uk] no start up screen

[norman]

When I switch my computer on the first thing I expect to see is a screen
about Intel and from which, if I so wish, I can access the bios set up.
Since installing Edubuntu this does not happen. All I get is a blank
screen plus an error message complaining about the video support. This
eventually changes to the usual signing on screen and there are no more
complaints. When I boot using Windows XP I get the Intel screen as
expected.

I know that Edubuntu performs as it should and there are no complaints
but I do like things to be correct. What can I do to try to identify the
problem and then put it right?
