AlphaServer 2100 500MP-5

I have one of these giant rackmount beasts.  I had an earlier 5.x running 
on it, but it won't seem to boot a 5.4 install CD.  It reads it, starts to 
boot (Screen goes black, and for a fleeting moment I see kernel stuff). 
Then I get:

halted CPU 0
halt code = 7
machine check while in PAL mode
PC = 14060

I have no idea how to check the kernel console to see the panic, if it did 
indeed panic, as it has VGA on it.

Any advice, or information on how to go about debugging this would be 
helpful.
