I just attempted to update the OBP on an Ultra-2 system (actually a Sparc-20
with an Ultra-2 motherboard upgrade) and now it refuses to boot. The old
version was:
OBP 3.7.8 1998/03/26 19:13 POST 3.3.1 1997/07/09
I downloaded Patch ID# 104169-08 and attempted to install:
OBP 3.25.0 199/12/03 11:35 POST 3.3.8 1998/11/16
Everything seemed to go smoothly (no errors were reported during erasing,
programming, and verification) until the first reset. The last thing I saw
displayed on the screen was:
Programming was successful.
Resetting ...
Next I am staring at a dark screen. The monitor led is is flashing every few
seconds, as if there is no video signal. Nothing seems to work. Typing in
the blind does not seem to have any effect. Power cycling seems to produce
the same conditions.
I dug out a NULL modem cable, set up a terminal session on serial port A
and cycled the power. After a few seconds, I received the following Fatal
Reset message and nothing further:
Fatal Reset
SC Control 0000.0000.0200.0000
SysIO status 0000.0000.0100.0000

SysIO CE AFSR 00ff.ffe0.0000.0000
CPU AFSR 0000.0001.a0f7.0048
SDBH AFSR 0000.0000.0000.0000
SDBL AFSR 0000.0000.0000.0000
On subsequent reboot attempts, the same info is displayed. Only the CPU AFSR
seems to change.
What does all this mean? And how can I fix it?
Thanks for any insights or assistance,
Tom Taylor
