Yes, this is how Dell's wonderful serial consoles work.  I have a DRAC
which is a dedicated card to handle remote server management including
remote console access, and I still can't see the BIOS messages once they
go over one screenful...

I've been wondering how hard it would be to write my own console
redirection code to fix this (not using VT100), but I don't think I'd be
able to load it early enough in the boot process to capture the BIOS.
Not unless I could stick my code in the video BIOS or something.  I'd
need help from someone at Dell for that though.  Hint hint. :-)

Don't use a serial console ;-)
