Ok, installed and up and running.

Just a couple of questions

1) What file do I need to edit to change the default OS from Linux to XP?

2) And I assume I need to edit something in the same file to add an option that allows me to go to a prompt rather than starting xwindows?

Edited to add a 3rd question

3) What partitions of what size should I have created when installing it? The installation instructions were a bit vague, although it seems to work ok so I must have done something right.
