Need old flash PROM for Ultra 5?

2007-12-24 20:18:00

Application of a flash PROM update (patch 106121-14, latest) on an Ultra
Sparc 5 is preventing the system from booting off burned CDs. At the OK
prompt I get one of two messages: (1) "The file just loaded does not
appear to be executable." or (2) "Fast Access MMU miss". I tried
installing a fresh boot block but it persisted in these errors. The
strange part is that it only affects CDs I burned which previously
worked. Unfortunately this is exactly the time I need to use one of
those CDs.

So I would like to back out my PROM flash. Only problem is Sun does not
provide my original PROM 3.15v2 in version 14 of the flash patch. (I
already tried going back as far as the patch offers, 3.25v0.) Where can
I locate an old flash PROM update so that I can go back to OBP 3.15v2? I
think I need patch "106121-05" or "106121-07" or earlier but it is
nowhere online and Sun doesn't provide any info in SunSolve about
backing out PROM updates.

Please Help.

Thanks,

Fred
