   Good to know. I seem to remember reading ( somewhere at sun.com? I'm not
   sure ) that CPU modules >300MHz(?) wouldn't work on the first (few)
   batch(es) of U5/U10 boards. So this change ( if at all ) apparently
   doesn't coincide with the graphic chip upgrade.


i have a u10/300 that won't take a /333 /360 or /400 module.
it goes into a cycling RED state at the prom at power up.

i am not sure i've checked it has latest firmware though.
