First of all many of the people who responded said that the U60's cannot
run on 2.5.1 11/97. That is incorrect. I run all of my U60's on that release.
The solution was given to me by Joe Kwan ( jkwan@Radar-Sci.Jpl.Nasa.Gov ),
Mike.Salehi@usa.xerox.com, mark baldwin ( mbaldwin@makesys.com )
who pointed out to me that there is a suppliment CD that is shipped
with all Suns whose CPUs are faster that 419 MHz. I mounted the CD
and followed the instructions on how to update my jumpstart image
and it worked perfectly.
The most interesting response that I got was from Mark Hargrave
(hargrme@wisdom.maf.nasa.gov ) who gave me a list of bootprom commands that
will actually slow down the CPU's to 404 MHz:
At the "OK" prompt, do the following:
also hidden
d# 404 at-speed
.speed (this should show the new CPU speed)
You can then try the jumpstart.
Once the system is rebooted, the clock speed goes back to 440 MHz.
I never had a chance to try this out.
Thanks for everyone's help !!
Dave
