Installation Difficulties

[eng at donut.ugcs.caltech.edu]

I've been having trouble getting the installation of 5.3R on
a Dell Precision 730 to work.
 

I booted from the mini-install iso.  The kernel loaded... no
console.  Quick check on google, I see that Marcel reports
that there is no VGA console.

I hook up a VT510 (emulating VT100) set 9600 N81... and
nothing.

What am I missing?  How do I get to the installer?
