Dell sent me a bootable sorta-DOS that displays a Windows95 splash screen.
Right now, that's what's on the server monitor. I can rconj into it and see
all the usual screens, but no combination of Alt+Esc, Ctrl+Esc, etc., works
to get me a normal looking screen.

One time, this happened and I thought the box was frozen but eventually (in
~10 minutes) it went away. This time, it's been there for hours.

Please suggest either ways to get the screen to change, ways to prevent the
splash screen for W95 from showing at all when the server starts, or ways to
obtain and install an alternative boot OS.

Thanks in advance very much.
