PROBLEM: Kernel panics on bootup

[Chris Snyder]

I can't get my Intergraph dual-P133 to boot.  The model number, 
according to the back of the case, is JHIF60H70.  Here's the error 
messages that are being displayed:

  <0>Kernel panic: Attempted to kill init!

(note: I typed these in by hand, on a teeny notebook keyboard.  If 
anything seems outrageous, let me know, and I'll verify it)
Kernel version is 2.4.18.  I noticed that it doesn't notice that there's 
an SMP motherboard - perhaps that has something to do with it?  This 
system has 256 MB EDO RAM (72 pin), a Mylex DAC960 RAID controller, a 
built-in SCSI controller (not sure what chipset, but supported by 
generic SCSI), and a tulip-based net card.  I'm attempting to boot it 
off of a SCSI Zip drive connected to the built-in SCSI (no bootable CD 
support).  This system was previously running NT4 SMP with no problems 
(well, other than the normal NT problems<g>).  Thanks in advance.
