*if* your PROM version supports the CPU it's a simple module swap.
If typing 'versions' in the Command Monitor gives you a date in
~1995 I think you are on the safe side. I guess earlier PROM
versions should also support the R4400 at 175 MHz. 200 MHz was
supported since July 1994, but it was also released a bit earlier.
