Is there a way where I can take the current snapshot and replace

boot with regard to where they pull the boot information from.
Whether it's off of the CD, or whether you use a file when you
create the iso to tell the CD how to boot. My thought is that I can
replace the silo version with the older one, or I can use lilo
maybe. Thanks for any help,

You've probably already tried it. You wrote in the first message
that you attempted an installation stable release of Debian (woody),
which contains the older SILO version. I have never build a bootable
Debian CD myself, but there is a debian-cd package which should help
you with it.
I tried tracing the execution path in the offending function, hoping
to spot some floating-point instructions which are causing the hang.
It turned out to be much harder than I've anticipated, so no
positive results were achieved. One way which might give us the
exact location of the failure is the information from the registers
on PROM console. Once the machine hangs (after issuing "FP Disabled"
message), press Stop-A to get back to PROM. If we are lucky, it will
be smart enough to store the values of the registers, including the
address of the last instruction executed. What I need is the output
of the commands .registers and ctrace from there (I hope you are on
the serial console). One important thing: you have to do it with
some installation media which I can access for debugging (since the
addresses are going to be image-specific). I recommend downloading
one of the RC2 iso images, for example the RC2 businesscard iso
image from
