Re: Installation Failing Sun V100

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

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
http://cdimage.debian.org/pub/cdimage-testing/sarge_d-i/sparc/rc2/sarge-sparc-businesscard.iso
