typing dos at the prompt should bring up the ntldr (if you have it), otherwise boot into nt. hitting the <tab> key should show you a list of what you can type.

if your nic isn't configured correctly, it takes a loooong time for this to timeout. go make lunch and come back, it should be done by then.
