Mike,
Thanks for the response. This is a stock install. I have a concern
that you may be able to address. Under z/OS we run an assembler program with
a B312 (LOAD AND TEST (long BFP)), which runs OK, ie no S0C1 RSN 000001. If
the 700 series has no support for BFP then how are we getting this result.

Subject: Re: Problem installing SLES8 under zVM 4.4 on an Amdahl 700
series pr ocessor
Michael,
we've had a quick look at this, it is obviously having problems running
the /linuxrc script where it is preparing a new root directory prior to
'switching' to it via the pivot_root system call.
These errors seem to be 'S0C1/PIC001' invalid opcode, looking at the
User Code data printed out the first thing that strikes us is the B3 and
ED opcodes, these are both Binary Floating Point
(IEEE).
The 700 series doesn't have a hardware IEEE unit but emulation is
provided by the Linux Kernel if the CONFIG_MATHEMU ifdef has been
defined during the kernel build.
We don't know if this is a 'stock' install kernel or if you have the
choice of kernels during the install phase, either way it looks like you
don't have emulation support for IEEE enabled.
Questions/comments ?
Regards
Mike Moss
